Abstract

The invention provides cell lysis solution for extracting animal DNA, a kit containing the lysis solution and a method for extracting animal DNA by using the kit. The cell lysis solution provided by the invention comprises Tris-base at a concentration of 20 to 30g / L, ethylene diamine tetraacetic acid (EDTA) at a concentration of 0.5 to 1.0g / L, sodium dodecyl sulfonate (SDS) at a concentration of 20 to 30g / L, NaCl at a concentration of 5 to 10g / L, urea at a concentration of 100 to 150g / L and the balance of sterile water, and the pH value of the cell lysis solution is regulated by NaOH to 8.0 to 9.0. When the animal DNA extraction kit provided by the invention is used, the extraction time is reduced by at least half hour compared with that in the prior art, the use of chloroform with strong toxic odor is avoided, the damage to the health of operators in an operation process is relieved, and the extracted DNA is high in yield and purity. The method provided by the invention is quick, simple, convenient, efficient and very repeatable. In the invention, the result is very stable, the success rate is high, extraction cost is reduced and large-scale extraction of DNA is easy.

Description

technical field [0001] The invention relates to the technical field of DNA extraction, in particular to a cell lysate, a kit and a method for animal DNA extraction. Background technique [0002] Since Watson and Crick proposed the DNA double helix model in the 1950s, molecular biology has achieved unprecedented development in breadth and depth. Our research on the molecular field has penetrated into various aspects such as biology, medicine, genetics and zoology. The extraction of genomic DNA is the most basic technology in molecular biology research and the guarantee for the success of follow-up experiments (see "Chicken Genome A Comparative Study of Different DNA Extraction Methods", Ma Xinhong et al.; Journal of Jiangxi Agricultural University, 2010.32(001): p.181-184). At the same time, the use of live blood collection and then DNA extraction from the blood can conduct polymorphism research and early selection of genomic DNA without killing animals, which is a very good...
