Analysis of KIR3DL1 expression levels on92 cases of normal donors for hematopoietic stem cells transplant

Objective To study KIR3DL1 expression level on NK cell surface of normal donors for hematopoietic stem cell transplantation(HSCT).Methods Ninety-two donors were performed by using of KIR genotyping,HLA high resolution genotyping and KIR3DL1 expression level using sequence-based testing(SBT),PCR-sequence specific primer(SSP)and flow cytometry methods.Results In 92 donors,the frequencies of KIR-A/A,Bx1。
