Abstract

The invention relates to the technical field of biology, in particular to a kit capable of being applied to high-throughput extraction of genome DNA from an animal tissue and an extraction method thereof. The kit capable of being applied to the high-throughput extraction of the genome DNA from the animal tissue comprises lysate buffer, binding buffer, a washing solution I, a washing solution II, eluant, protease K and magnetic beads, the composite effect of reagents is utilized to fully digest, split, damage cells for removing proteins to obtain high-purity DNA. Compared with a kit sold in themarket, the kit capable of being applied to the high-throughput extraction of the genome DNA from the animal tissue has the advantages that the pyrolyzing rate is quick, the extraction purity is high, the extraction volume is large, the used reagents are safe, stable and efficient, the kit is especially suitable for high-throughput automated production, so that the extraction efficiency of the genome DNA is greatly improved, the error is reduced, and the extraction is more accurate.

Description

Technical field: [0001] The invention relates to the technical field of molecular biology, in particular to a kit and an extraction method applicable to high-throughput extraction of genomic DNA from animal tissues. Background technique: [0002] Donkey skin is the dry skin or fresh skin of equine animal donkey (Equus asinus L.), which is the raw material for preparing traditional Chinese medicine donkey-hide gelatin. Donkey-hide gelatin is the treasure of health care in China and has a long history. The Han "Shen Nong's Materia Medica" is listed as the top grade, and the Ming "Compendium of Materia Medica" is listed as the best nourishing product, the product of flesh and blood, the most nourishing, and has been used as a beauty product for women in all dynasties. Donkey-hide gelatin has the functions of nourishing qi and blood, enhancing physical fitness, strengthening the heart and lungs, strengthening muscles and bones, and beautifying the skin. In recent years, with t...
