Abstract

The invention relates to an excellent skiing sportsman enriched cDNA (complementary Deoxyribonucleic Acid) library and a construction method thereof. A high-quality excellent skiing sportsman enriched cDNA library with high titer, high recombination rate and large insertion fragment range is obtained by performing total RNA (Ribonucleic Acid) extraction, double-chain cDNA synthesis, digestion using protease K, Sfi1 enzyme digestion, connection into a vector and package of lambda phage. The invention belongs to the field of interdiscipline of sports science, human resource methodology, cell biology and molecular biology.

Description

technical field [0001] The present invention relates to a cDNA library and its construction method. Specifically, the blood samples of several excellent ice and snow athletes are used to extract total RNA, mix total RNA, synthesize double-stranded cDNA, digest with proteinase K, digest with Sfi1 and connect to a carrier, The packaging of λ phage finally obtained the enriched cDNA library of excellent ice and snow athletes. Background technique [0002] Human genetic resources are irreplaceable resources for human beings to conduct their own exploration and research. Human genetic resources refer to the genetic material representing human genes. In today's world, the people who can best represent human's own physical fitness genes are excellent athletes in various sports. As a part of human genetic resources, sports genetic resources are precious wealth of human beings. However, due to the limitation that sports genetic resources only exist in individual athletes, if we do n...
