Abstract:We describe a reliable and semi-automated method for Killer-cell Immunoglobulin-like Receptor (KIR) 3DL1/S1 genotyping using DNA recovered from frozen plasma. The primers and protocol were first validated using two independent genomic DNA reference panels. To confirm the approach using plasma-derived DNA, total nucleic acids were extracted from 69 paired frozen PBMC and plasma specimens representing all common KIR3DL1/S1 genotypes (3DS1/3DS1, 3DS1/3DL1 and 3DL1/3DL1, including rare allele 3DL1*054), and analyz… Show more
