Reagent kit for sifting carrier of bovine uridine monophosphate ribozyme deletion disease

Abstract

The invention discloses a reagent box of screening the carrier of missing uridine monophosphate ribozyme of ox. The reagent box comprises a PCR primer pair and an endonuclease AvaI. The PCR primer pair comprises a primer pair comprising a deoxyribonucleotide with the sequence 1 in the sequence table and a deoxyribonucleotide with the sequence 2 in the sequence table. In the detection method of DUMPS heterozygote on herb based on genome DNA, the PCR-RFLP method is utilized to directly classify the genotype of Holstein cow, the method is not affected by animal age, sex and gene expression time, no radioactivity is used, no collection of comparison sample is required, and not only the determination work is reduced, but also the determination accuracy is promoted. Using the method to screen the carrier of missing uridine monophosphate ribozyme does not need special instrument and is favorable for the requirement of the conventional laboratory detection.

Description

technical field [0001] The invention relates to a kit for screening bovine nuclease deficiency carriers. Background technique [0002] Holstein dairy cow is a dairy cow variety widely used all over the world. After a high degree of breeding and good feeding management, its production performance has been continuously improved, and it is playing an increasingly important role in human life. In recent years, due to the continuous selection of breeding and matching, the inbreeding between dairy cows has been increasing. At present, most of the Holstein cattle in the world can be traced back to a few particularly excellent breeding bulls in North America. In my country, a large number of imported breeding cattle, embryos and frozen semen increase the risk of rapid spread of genetic defects. Therefore, it is necessary to gradually establish a sound detection and prevention and control system. [0003] Genetic defects refer to structural or functional changes in the genetic mater...

Problems solved by technology

By comparing the bovine UMPS gene with human and Dictyostelium discoideum (Dictyostelium) sequences, it was found that the possible region of the catalytic active center was highly conserved (Michel Jacquet et al, 1988, Sequence analysis of the DdPYR5-6gene coding for UMP synthase in Dictyostelium discoideum and comparison with orotate phosphoribosyl transferases and OMP decarboxylases, Mol. Gen Genet, 1988, 211: 441-445), but the middle region belonging to the connecting peptide is poorly conserved
