genotyping assay killer cell immunoglobulin-like receptor typing assay DNA was isolated from PBMCs from healthy donors.The single-nucleotide polymorphism (SNP) assay was performed on an HT7900 Sequence Detection System (Applied Biosystems) following the allelic discrimination assay protocol provided by the manufacturer. Primers for the assay were designed in such a way that they amplified all the alleles of a particular HLA type (HLA-B or HLA-C) as well as the amplicon containing the polymorphic region of interest. Two probes were designed with a single mismatch between them. Each probe bound only one group of alleles and was labeled with either 6FAM or VIC fluorescent dye at its 5_ end. The 3_ end of the probes contained a quencher. For KIR2DL1 functional allele typing, the probe was designed based on a single-nucleotide mismatch at amino acid position 245 in the mature protein. A universal primer was designed that could specifically amplify all the alleles of KIR2DL1.The SNP assay was run on the HT7900 using the same protocol as described for KIR ligand typing. Results showed that 20 individuals had only arginine at amino acid position 245 of KIR2DL1, 5 were heterozygous for arginine and cysteine, and 1 had only cysteine in that position.Thus, this approach was useful not only for the identification of functional groups of KIR alleles, but also for determining the presence of the KIR gene itself. A genotyping assay in which the alleles of genes encoding for killer cell immunoglobulin-like receptors are determined. PMID:21239231 Genotyping assays should ideally identify which part of the genome the information is about. We do not currently have a good way to do this. That information should be added later. killer cell immunoglobulin-like receptor typing assay ImmPort KIR typing metadata complete
