What does the KQ value of porcine orchid ear antibody mean, and how much is it qualified

The kq value is the s p value.

Just multiply more by 100. For example, the detection of PRRS virus antibodies in porcine serum using the Pre-Biotech ELISA kit (indirect ELSIA method) was used only when the positive control OD630 nM and the negative control were used.

OD630 nm was held and the kq value was calculated. kq = (sample OD630 nm positive control OD630 nm average.

100, when KQ 20, judged to be antibody positive, KQ 20, judged to be antibody negative.

Two points should be noted: (1) The kit must meet the specified conditions under the conditions of the measured values of the negative and positive controls before the kq value of the sample to be tested can be calculated, otherwise the results are meaningless. (2) Any testing products produced by any company, even for different testing objects, the judgment method and basis may be different, there is no absolute right or wrong, it is best to combine a variety of testing methods, multiple tests and then draw conclusions.

For example, if the measured value of positive control serum OD630 is equal to, the measured value of negative control serum OD630 is equal to, and the OD630 of a serum sample to be tested is equal to, the antibody of the serum sample to be tested can be determined to be positive according to "20". However, when considering that the OD630= of the serum sample to be tested is smaller than that of the negative control, the judgment made may be incorrect, i.e., the serum sample to be tested is likely to be antibody negative.

The KQ value of porcine orchid ear antibody refers to a method for the detection of PRRS virus antibodies in pig serum, and its formula is as follows: KQ = (sample OD630 nm positive control OD630 nm average) 100.

According to the regulations, when the KQ 20 is judged, it is judged to be positive for antibodies, that is, qualified; When the KQ < 20, it is judged that the antibody is negative, that is, it is unqualified.

If the KQ value is 20, it is judged to be PRRS.

positive for viral antibodies;

If the KQ value is < 20, it is judged to be negative for PRRS virus antibody.

Science and engineering majors refer to majors that study both science and engineering. Science and engineering is a vast field that includes physics, chemistry, biology, engineering, astronomy, mathematics and the various applications and combinations of the previous six categories. Science and engineering are, in fact, a combination of nature, science, and technology.

Science is an important discipline in Chinese university education, which refers to the study of the basic laws of the motion of natural matter. Together with literature, engineering, education, history, etc., it forms the discipline system of higher education in China.

The content of science research is extensive, and undergraduate majors usually include: Mathematics and Applied Mathematics, Information and Computing Science, Physics, Applied Physics, Chemistry, Applied Chemistry, Biological Sciences, Biotechnology, Astronomy, Geology, Geochemistry, Geographic Sciences, Resources, Environment and Urban and Rural Planning and Management, Geographic Information Systems, Geophysics, Atmospheric Sciences, Applied Meteorology, Marine Science, Marine Technology, Theoretical and Applied Mechanics, Optics, Materials Physics, Materials Chemistry, Environmental Science, Ecology, Psychology, Applied Psychology, Statistics, etc.

Engineering (discipline**:08) refers to the general term of engineering disciplines. Including instrumentation, energy and power, electrical information, transportation, marine engineering, light industry and textile, aerospace, mechanics, biological engineering, agricultural engineering, forestry engineering, public security technology, plant production, geology and minerals, materials, machinery, food, civil engineering, water conservancy surveying and mapping, environment and safety, chemical and pharmaceutical, etc.

That is, you will graduate with a Bachelor of Science or a Bachelor of Engineering.

It's your Bachelor of Science or Bachelor of Engineering.

There is information on how to improve your science and engineering background in the library, you can take a look. Figure it out for yourself.,It's hard to explain the specifics.。。。 You can only understand it, and make up the ...... of the lesson

Science and engineering girls are more suitable for the following majors:

1. Economics and Finance: such as International Economics and Finance, Accounting, Finance, Public Finance, etc. If you are engaged in finance, you can go to a bank, accounting office, public institution as an accountant, etc.

2. Language majors: foreign languages, including minor languages. English, Korean, Japanese, French, German, etc., are becoming more and more popular with China's internationalization.

Foreign language classes have a wide range of employment, and you can go to colleges and universities and tutoring institutions to teach. You can also go to foreign companies and multinational companies to translate. Especially for simultaneous translation, the salary is very high, and the science girls are clear and careful, especially suitable for learning.

Especially for simultaneous translation, the salary is very high, and the science girls are clear and careful, especially suitable for learning.

3. News and broadcasting majors: journalism, advertising, radio and television journalism, publishing, etc. Female students in science are very suitable for studying this major, because girls are born with particularly strong language skills, and their thinking in science has more employment advantages.

Compared with traditional journalism, radio and television studies have greatly expanded to the field of "speaking" beyond the scope of "writing", and it emphasizes more on broadcasting in front of the stage and program production behind the scenes. Therefore, while "writing", students should also practice a "three-inch tongue".

4. Applied Psychology: In today's society, there is great pressure of competition, various problems have arisen, and people's psychological problems have been paid more and more attention. This major is suitable for the psychological characteristics of science girls, and it is easy to learn deeply.

The program covers almost all applied sciences, such as education, industry, business, medicine, military and other fields. Due to the lack of psychology in the history of the development of domestic disciplines, there is a great shortage of professionals, especially senior professionals. However, since most of this major is located in normal colleges, most of the undergraduate graduates choose to work in primary and secondary schools, both now and in the future.

5. Major in law, including law, intellectual property, etc. Law students are not only eloquent and quick in thinking, but also have a strong ability to deal with problems. With the establishment of the basic national policy of governing the country according to law, in the long run, the employment of graduates of the law major, as a "sunrise" major, has great prospects for development.

In addition, the awareness of rule of law and democracy in all sectors of society is increasing day by day, and the demand for legal professionals is growing rapidly.

Girls in science and engineering should not choose those very masculine majors, such as computers, civil engineering and machinery, this kind of major is not easy for girls to find a job after studying, and related jobs are not suitable for girls to do it will be very hard, science and engineering can choose medical normal schools, now psychology is more popular, pharmacy majors can also be, after graduation you can go to pharmaceutical companies, journalism and communication majors are also more suitable for girls with better writing, after graduation to go to newspapers and television stations, teachers are very suitable for girls to choose, The treatment is very good, there are winter and summer vacations, the work is not tired, the parents are very respectful, and there are financial majors, such as finance, etc., but this kind of major is generally not good for employment now, because it is more extensive and not specialized, unless you have a particularly good school, the choice of major also depends on the current situation of the country, just like sailing down the river, do not choose those industries that have declined and have no development prospects.

Choose the region first, then the school, and finally the major. The choice of the region is mainly for the future career development of the city, the choice of school and major can be put together, for example, if you are interested in being a teacher, you can choose a normal college, the same is true for the major. If you don't have a favorite major to choose from, then I recommend female students to study accounting, design, and engineering majors.

Finance major is better for female students, and they will work in a bank or **, financial department in the future, with a good working environment, high craft income, and a warm working environment in winter and cool in summer, which is more suitable for girls. In addition, it is not bad to be admitted to a normal college to become a teacher in the future, and it is also good for girls to have holidays and rest days!!

Female students in science and engineering can study finance, economics, teachers, and doctors, and it is easy to choose if you have a high score, but you can choose a narrow choice if you have a low score.

Choose a career you like, as long as you like to learn anything, regardless of whether you like it or not, it is recommended to learn a job that is easy to find, such as business management, etc.

Female engineering students, chemistry majors are better, such as new energy majors, medicinal chemistry, clinical medicine, nursing, and such majors have very good employment prospects.

I think that as a science and engineering subject, there are only majors that are not suitable for girls, and there are no majors that are suitable for women, and I hope you understand what I mean

It is more reliable to combine your college entrance examination score and the admission score line of the school over the years to fill in the application. It's quite popular to study teacher training now, you can consider it.

It doesn't matter what major a science and engineering girl is. Don't have a patriarchal mentality. Majors that can be studied by boys can be studied by girls.

In the past two days, the most I listened to the lectures was the knowledge of chemistry and chemical engineering, and the girls in science and engineering majored in chemistry.

It doesn't matter what you major, as long as you like it, if the boy can learn well, the girl will definitely be able to learn well. Believe in yourself and keep it up! It doesn't matter what you major, as long as you like it, if the boy can learn well, the girl will definitely be able to learn well.

First of all, you should learn what you like, and you may be well paid in the future if you choose an unpopular major, but you must also learn well enough.

All majors are female doctors! It mainly depends on what major you want to study, and this is mainly your own idea! You must be interested in the major you are applying for, and you must like the major you are reading, otherwise it will be bad if you are tired of reading.

Personally, I think the best thing for girls is medicine. Of course, if you are interested in a certain major, then you might as well apply for the major you are interested in. It's best to do what you can get into the major you love.

In college, the concept of liberal arts and sciences has been diluted, and the major is decided based on one's hobbies, and there is no best, only the most suitable one.

There are many majors suitable for girls, such as teachers, doctors, accountants, nursing, computers, auditing, statistics, management, etc.

Depending on what you like, doctors, science and engineering teachers, accountants, are all suitable for girls.

Each major has its own advantages and disadvantages, and there is no distinction between men and women. Besides, the major is the best, what is the use if you don't study hard. The key is that you choose a major that you like. Then it is the king to study hard.

Judging from the current situation, in fact, it is very good to choose to learn computers, and you basically don't have to worry about finding a job when you come out, and some can also start your own business.
