Embodiment 1

[0105] This example gives an example of HLA-A, -B, -C absolute high-resolution sequencing typing of 300 cases of Shenzhen patients requiring hematopoietic stem cell transplantation and their donor samples.

[0106] Selected 300 samples of known HLA-A, -B, -C serotypes, and carried out sequencing typing with the corresponding group-specific PCR amplification primers and sequencing primers of the present invention to verify the implementation effect of the present invention .

[0107]For each sample, first, according to its HLA serology, select corresponding group-specific PCR amplification primers as described in the first aspect of the application to perform PCR on the full-length sequences of HLA-A, -B, and -C of the sample Amplification reaction, amplification reaction conditions: All amplification reactions are set with the same reaction system, the composition is as follows:

[0108]

[0109] After the PCR reaction system is set up, all reactions are amplified synchron...

Abstract

The invention relates to biomedicines and immunological genetics and particularly relates to a group-specific amplification primer, sequence-based typing method and a kit for HLA genes. Sequences of a PCR amplification primer are selected from sequences represented by SEQ ID NO.1-28, sequences represented by SEQ ID NO.29-64 and sequences represented by SEQ ID NO.65-94. By designing the group-specific amplification primer by carrying out serum classification on the HLA genes, all allelic genes including HLA-A, -B and -C can be subjected to sequence-based typing; by carrying out amplification sequence on full-length sequences of genes HLA-A, -B and -C, the ambiguity can be effectively solved, an absolute high score is achieved, and data is relatively accurate and reliable.

Description

technical field [0001] The invention relates to biomedicine and immunogenetics, in particular to a group-specific amplification primer for HLA genes, a sequencing typing method and a kit. Background technique [0002] Human leukocyte antigen system (HLA) is the most diverse and important immunogenetic system in the human genome. Its diversity determines the body's resistance to infectious diseases, autoimmune diseases, genetic diseases and various tumors. In clinical application, the matching degree of its gene polymorphism between donor and recipient directly determines the survival rate of hematopoietic stem cell transplantation and organ transplantation patients. [0003] In the field of HLA tissue typing industry, there are currently three major shortcomings in the products in the domestic and foreign markets: First, most of the products only type for some exons of HLA genes, such as only for HLA-I genes (including The exons 2, 3, and 4 of HLA-A, -B, and -C) are tested ...
