KIR3DL2 genotyping kit and KIR3DL2 genotyping method

Abstract

The invention discloses a KIR3DL2 genotyping kit and a KIR3DL2 genotyping method. The KIR3DL2 genotyping kit comprises an amplification primer 1, an amplification primer 2, an amplification primer 3, an amplification primer 4, an amplification primer 5, an amplification primer 6, a sequencing primer 1, a sequencing primer 2, a sequencing primer 3, a sequencing primer 4, a sequencing primer 5, a sequencing primer 6, a sequencing primer 7, a sequencing primer 8, a sequencing primer 9, a sequencing primer 10, a sequencing primer 11, a sequencing primer 12, a sequencing primer 13, a sequencing primer 14, a sequencing primer 15 and a sequencing primer 16. The KIR3DL2 gene is subjected to PCR amplification by virtue of multiple amplification primers, the amplified PCR product is subjected to sequencing amplification by virtue of multiple sequencing primers, and then the sequencing amplification product is sequenced, so that a new allelotype which is difficult to identify by virtue of other methods is found, and high-resolution typing of the KIR3DL2 gene is realized.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a KIR3DL2 genotyping kit and a typing method. Background technique [0002] Natural killer cells (Natural Killer cells, NK cells) in the human body through cytokines and cytotoxicity, resist infection and kill malignant cells, play an important role in innate immunity and acquired immunity. Killer cell Immunoglobulin-like Receptor (KIR) is a group of immunoglobulin-like superfamily members mainly expressed on the surface of NK cells and some T cells, which can specifically recognize human major histocompatibility Sex complex MHC-I molecules (Human Leukocyte Antigen I, HLA-I), mediate and regulate the killing function of NK cells and some effector T cells. More and more evidences from clinical transplantation and animal experiments suggest that the heterogeneous response of NK cells triggered by KIR incompatibility between donor and recipient is beneficial to the prognosis of allogen...
