Generally will be between 10mg-1mg g leaves.
The yield root experimental method (there are many extraction methods) has a lot to do with it, and the higher the requirement and the purer the yield, the lower the yield.

Summary. Pro-<>
We are glad to answer the question of extracting macromolecular DNA from plant leaves and verifying the experimental results: the CTAB method is a quick and easy method to extract total DNA from plants: first grind fresh leaves in liquid nitrogen, break up their cells, then add CTAB separation buffer to dissolve the DNA, and then remove the protein by chloroform-isoamyl alcohol extraction, and finally obtain DNA.
Validation is: Phosphorus determination method: It is an accurate quantification of the nucleic acid (DNA and RNA) content in the sample.
The nucleic acids in the sample are digested with a strong acid (sulfuric acid or perchloric acid) into inorganic phosphorus, and the resulting inorganic phosphoric acid is titrated with a phosphorus determination reagent. The phosphorus determination reagent is an acidic ammonium molybdate solution, which can be quantitatively combined with inorganic phosphoric acid to form a phosphomolybdate complex, which can be reduced into blue molybdenum blue by reducing agents such as ascorbic acid, and has maximum light absorption at 660mm.
Macromolecular DNA was extracted from plant leaves and the results were validated.
I would like to know how to test the results of the experiment.

In the process <>of DNA extraction and preparation, nucleic acids are extremely unstable, and many factors can destroy their complete structure: Chemical factors, the structure of nucleic acids is relatively stable between pH values, and the pH value will denature and degrade nucleic acids outside this range, so the preparation process should avoid excessive acid and alkaline. Physical factors, the DNA molecular chain is very long, it is a double helix structure, and it has a certain flexibility.
It also has a certain degree of rigidity, so strong mechanical action such as vigorous agitation will cause DNA molecules to break, which is not conducive to collection, and should be avoided.

Bolinco is the new fast.
Plant genome.
DNA extraction kits.
The improved CTAB plant DNA extract (adding a variety of polysaccharides and polyphenols to remove components according to plant characteristics) rapidly lysed cells and inactivated intracellular nucleases, and after chloroform extraction, polysaccharides, polyphenols and proteins were removed by centrifugation, and the supernatant was centrifuged with isopropanol centrifugation.
Precipitation of genomic DNA and further removal of various others.
Impurities, genomic DNA is then selectively adsorbed to the silica-based membrane in the spin column in a state of high detached salts, and then through a series of rapid rinsing and centrifugation steps, the polysaccharides, polyphenols, and cells are further absorbed.
Metabolites, proteins and other impurities are removed, and finally low-salt elution.
The buffer elutes the genomic DNA from the silicon-based plasma membrane.
Kit Features:
The silicon matrix membranes in the centrifugal adsorption column are all imported and specially made.
Adsorption membranes, between columns.
The difference in adsorption capacity is minimal and reproducible.
Good. Overcome domestic production.
Disadvantages of unstable membrane quality in kits.
There is no need to use toxic ones.
Phenol, chloroform and other reagents.
Fast, simple, single.
Sample handling can generally be completed within 1 hour.
The density of water is grams of cubic centimeters, and 1 cubic centimeter is equal to 1 milliliter, so the volume of 1 gram of water is 1 milliliter!
It is actually called "Xinyi Flower", and the pharmacy is 5 yuan taels. What is 10-15 yuan grams, it is generally sold during travel. If you beat it into powder and weigh it again, a few hundred grams will cost thousands of yuan.
Seven years after the birth of a small or medium-sized dog, or five years after the birth of a large dog, it is already slowly entering old age. In order for the dog to survive happily, the dog owner should do something for him. In terms of the health of the dog, how to calculate the life expectancy of the dog: >>>More
As its name suggests, the Guanyin lotus is a relatively common variety of succulents. There are many kinds of Guanyin lotus, different sizes, it is a very good choice to make potted plants, and it looks simple and elegant in the study, living room, and office, and is full of poetry and picturesqueness. Guanyin prefers a humid environment and avoids direct sunlight, but it should not leave a lot of stagnant water in the basin. >>>More
