What is type specificity ? Specific vs. non specific

Antibodies are specific.

Ahh There are many epitopes present on the surface of the antigen.

Also called epitope. Each epitope binds to one antibody, so an antigen can bind multiple antibodies at the same time, but an antibody binds only one antigen.

By cultivating the patient's own anti-cancer cells in vitro and then infusing them back into the patient's body, the purpose of scientific anti-cancer is achieved. With the help of biological agents, it is cultivated and injected into the human body, and the most efficient specific immune cells DC, CIK, T and NK cells in the human body work together to mobilize the defense mechanism of the patient's body, so as to regulate the biological response of the patient's body, kill cancer cells, activate immune cells, and kill the remaining tiny cancer cells in the body, so as to achieve the purpose of starting the tumor from the root. Specific and unique ** mode, what cells are missing in the patient's body, what cells are cultured, more targeted.

1.Paired, groups of objects must correspond to each other. For example, a key, a lock, a key, the existence of a specific corresponding lock.

For example, the mutual discrimination and selective binding reaction between enzyme-substrate, antigen-antibody, and ligand-receptor is the conformational correspondence between the corresponding reactants from the perspective of stereostructure. Enzyme specificity refers to the ability of an enzyme to distinguish between two or more different substrates, and bind to one of the most conformationally appropriate substrates to catalyze the chemical reaction of the substrate, showing that the enzyme has strict selectivity for its substrate. This phenomenon can be explained by the theory of induced wedges, which induces allosterism of enzyme proteins when the enzyme is in close proximity to the substrate.

On this basis, the enzyme reacts with the substrate complementary wedge. X-ray diffraction analysis showed that the enzyme had a significant conformational change when binding to the substrate.

2.The numerical size of a certain index nature that distinguishes the observed object from its ** group.

Plant variety specificity: It means that the new plant variety for which the variety right is applied should be clearly distinguished from the plant variety known before the application was submitted.

DNA Match Specificity: Refers to the obvious difference between the DNA to be tested and the comparator.

The second point of the meaning is proposed based on the explanation of sensitivity and specificity (medical statistics).

In the medical system, any diagnostic index has two most basic characteristics, namely sensitivity and specificity, the so-called sensitivity refers to the probability of not missing the diagnosis (false negative) when diagnosing the disease, and the so-called specificity refers to the probability of the index not being misdiagnosed (false positive) when diagnosing a disease.

Specificity refers to the purpose of scientific anti-cancer by cultivating the patient's own anti-cancer cells in vitro and then infusing them back into the patient's body. Unique** pattern of specificity: what cells are missing in the patient's body, what cells are cultured, more targeted.

Non-specific immunity is something that a person is born with, and specific immunity needs to go through a process to acquire. Inflammation is an innate ability. Innate immunity can respond rapidly to various invading segment-round pathogenic microorganisms, and also plays an important role in the initiation and effector process of specific immunity.

The main differences between specific and non-specific immunity are as follows:

First, the characteristics are different.

1. Specificity: specificity (or specificity); have immune memory; There are positive and negative reactions; There are a variety of cells involved; Song Burn has the characteristics of an individual.

2. Non-specific: wide range of action; Quick response; There is relative stability; hereditary; It is the basis for the development of specific immunity.

Second, the functions are different.

1. Specificity: What is obtained after birth can only have a defensive effect on a specific pathogen.

2. Non-specificity: Non-specific immunity is the basis of specific immunity, and the immune substances produced by specific immunity can enhance the role of non-specific immunity.

Third, the method of obtaining is different.

1. Specificity: It is the ability of the human body to resist infection through acquired infection (cured or asymptomatic infection) or artificial vaccination (vaccines, Yexun vaccines, toxoids, immunoglobulins, etc.).

2. Non-specific: people are born with it.

"High or low specificity" is a medical or biochemical term often used to describe the accuracy or sensitivity of a certain biomolecular detection method. Specifically, specificity indicates how well a detection method can distinguish and how accurate it is to detect the target molecule. In biomolecule detection, the target molecule may have similar structures and characteristics to other biomolecules, so the specificity of the detection method can determine its accuracy and reliability.

When the specificity of the test is high, it means that it can accurately identify the target molecule and the non-target molecule will not be detected, which often leads to more accurate and reliable detection results. Conversely, if the specificity of the detection method is not high, the circular calendar may lead to false positives or false negatives, which can affect the accuracy and reliability of the test results.

Therefore, when choosing a biomolecular detection method, many factors need to be considered, including specificity, sensitivity, reliability, accuracy, etc., to ensure that the selected method can achieve the expected detection effect.
