Abstract

The invention relates to a yak molecular marker-assisted breeding technology in the technical field of animal biology and specifically relates to a yak meat tenderness candidate gene detection kit. The yak meat tenderness candidate gene PCR (polymerase chain reaction)-SSCP (single-strand conformation polymorphism) detection kit is characterized by comprising a PCR solution, DNA (deoxyribonucleic acid) standard samples of CAPN3*B and CAPN3*C, an SSCP detection reagent, deionized water, 10% of ammonium persulfate, a loading denaturation buffer solution, TEMED (N, N, N', N'-tetramethylethylenediamine) and 12% of non-denatured polyacrylamide gel, wherein Arc: Bis in the non-denatured polyacrylamide gel is 37.5: 1; the loading denaturation buffer solution comprises 98% of deionized formamide, 0.025% of bromophenol blue, 0.025% of xylene cyanol FF and 10mmol/L of EDTA (ethylenediamine tetraacetic acid) with pH value of 8.0. The yak meat tenderness candidate gene detection kit provided by the invention has the characteristics of high speed in molecular marker breeding of yak, high sensitivity, low cost and the like.

Description

technical field [0001] The invention relates to yak molecular marker assisted breeding technology in the field of animal biotechnology, in particular to a yak meat tenderness candidate gene allele detection kit and a detection method thereof. Background technique [0002] Calpain (CAPN) is a class of calcium-dependent cysteine ​​neutral proteolytic enzymes present in the cytoplasm of vertebrates, which is dependent on calpastatin (CAST) and calpain activator The proteolytic enzyme system based on calcium ion plays an important role in the maturation and tenderization of animal muscles after slaughter. Mammals have discovered 16 kinds of calpains, among which CAPN1, 2, 4, 5, 7, 10, 13, 14, 15 and 16 are widely expressed in animal tissues, while CAPN3, 6, 8, 9, 11 and 12 are specific calpain. [0003] The CAPN3 gene of common cattle is located on chromosome 10. There is a certain difference in the correlation between the SNPs of the CAPN3 gene of zebu and common cattle and t...
