Quantitative Multiplex Real-Time Reverse Transcriptase-Polymerase Chain Reaction with Fluorescent Probe Detection of Killer Immunoglobulin-Like Receptors, KIR2DL4/3DL3.

ABSTRACT: (1) Background: KIR2DL4/KIR3DL3 are the framework genes present in all KIR haplotypes, with unique expression patterns being present only in women and CD56bright NK cells. KIR genes have a high degree of DNA sequence identity. Consequently, they are one of the most challenging genes for molecular detection-especially regarding expressions; (2) Methods: We developed an effective method to determine KIR3DL3/KIR2DL4 expressions based on a multiplex quantitative real-time Reverse transcription polymerase chain reaction (qRT-PCR )with fluorescent probes using NK92; (3) Results: Standardizations of the singleplex KIR2DL4 and KIR3DL3 were performed to evaluate the sensitivity and specificity for further development of the multiplex assay.
