Method for extracting genome DNA of poultry
InactiveCN101768588ANo obvious tailingHigh purityMicrobiological testing/measurementDNA preparationBiologyBlood preservation
The invention discloses a method for extracting genome DNA of poultry, applied to large-scale collection, separation and purification of genome DNA of poultry in the actual production. Based on the condition that the poultry blood corpuscle contains a karyon, the method for extracting genome DNA of poultry in the invention proposes a principal that the DNA genome can be extracted once the poultry blood is taken out, completely saving the steps of anticoagulation and blood preservation; the method also proposes that blood is taken from the plantar vein, realizing simple and efficient blood sample collection and less stimulation to the poultry, and furthest avoiding reduction of egg and meal yield because of blood taking. The blood sample not more than 20mul in each poultry is taken on spot and then directly put into a 1.5ml centrifugal tube and mixed with the 700mul of poultry blood lysate in the centrifugal tube, put into an ice-cube box and taken back to the laboratory for DNA extraction; the whole process is secure and reliable, and biological security danger caused by massive poultry blood transport is reduced. Aiming at the problem that protein pollution easily occurs in the poultry blood extraction process, the method of the invention proposes that the DNA is extracted according to the original phenol method, but the saturated phenol is treated for two times and centrifuged at four degrees, thus the protein pollution is extremely reduced, the purification of the extracted DNA is much improved, and the subsequent molecular detection is much facilitated.
