The rapid duck gender identification kit body consists of a kit body, a liner of the kit body, and a specific primer mixture ZWp, an amplification buffer solution, a DNA marker and agarose which are respectively arranged in each hole cavity of the liner. According to the kit body, a PCR (Polymerase Chain Reaction)-agarose electrophoresis technology is adopted to detect the fragment sizes of PCR products, and the gender of an individual is identified according to the fragment sizes and quantity of the PCR products. The rapid duck gender identification kit body has the advantages of high accuracy, rapidness and low cost.
Description
Technical field
The utility model belongs to biological technical field, and a kind of test kit that carries out fast the sex identification of duck is provided, and this test kit is used for PCR-agarose electrophoresis technology.
Background technology
The sex of poultry is determined by W karyomit(e) and Z chromosome, poultry female gene type is the ZW type, and male genotype is the ZZ type, and the probability that Z or W pass to filial generation is the same, be 1/2nd, its mode of inheritance is followed the Mendelian law of independent assortment and the law of independent assortment.Up to the present, find to have minority to be distributed in gene on bird Z and the W karyomit(e), they do not appear at false euchromosome district, but all are to occur with W and the single copy of Z, and exist with the form of the non-restructuring part of two types in sex chromosome.
That have characteristic feature most is CHD1Z--CHD1W(chromodomain helicase DNA binding protein 1) gene, research thinks that their in all birds (except ratites) are chain with W or Z respectively.Because some introns are different from sequence size among the CHD1W at gene C HDIZ, use the conservative property primer, just can pass through PCR-agarose electrophoresis technology, clip size and quantity according to the PCR product, judge male genotype (ZZ type, a large PCR product fragment) and female gene type (ZW type, small one and large one two PCR product fragments).These two kinds of genes are independently evolved, and use the Direct PCR technical Analysis, for research birds (except ratite) molecule sex determination provides approach.Along with going deep into that the subjects such as fetology, developmental biology and molecular biology of duck are studied, the evaluation of duck embryonic early sex becomes a problem in science.Through the retrieval to existing domestic and foreign literature and patent, so far there are no the research report of the duck CHD of family gene complete sequence and molecular sex identification.
The utility model content
The purpose of this utility model is in order to provide a kind of rational in infrastructure, cheap gene type test kit to duck sex Molecular Identification.
The purpose of this utility model is achieved through the following technical solutions, the quick identification reagent box of a kind of duck sex box body, described test kit is by box body, liner in the box body, the Auele Specific Primer mixture ZWp that inserts respectively in each vestibule of liner, amplification buffer, DNA marker and agarose form.
Wherein the ZWp details are as follows:
Primer mixture ZWp represents that primer information is as follows for the upstream and downstream primer mixture of CHD gene PCR amplification:
