چکیده
BACKGROUND Commercial kits of PCR method are widely used in HLA-B27 typing; however, their cost is relatively high. In this study, we evaluated the utility of an in-house PCR method by comparing it with that of a commercial kit. METHODS HLA-B27 typing was done in 188 patients by using two PCR methods, Absolute HLAB27 PCR kit (Biosewoom, Korea) and an in-house PCR method. The primers used in the in-house method were prepared by Bioneer (Korea). Both PCR tests were done by Gene Amp PCR System 9600 (Perkin-Elmer Centus Corp., USA). RESULTS The commercial kit and in-house PCR showed 100% concordance rate with each other in HLA-B27 typing. Of 188 patients tested 72 (38.3%) were positive and 116 (61.7%) were negative by the both tests. Of 62 patients with ankylosing spondylitis, 50 were positive (80.7%). CONCLUSIONS The in-house PCR is a reliable and cost-effective method and can replace or supplement commercial kits for HLA-B27 typing.

The Human Major Histocompatibility Complex (MHC) plays a crucial role in transplantation, transfusion, paternity test and assessment of susceptibility to some diseases associated with HLA-B27. Three of the most fashionable methods for determination of HLA antigens in clinical and research laboratories are microlymphocytotoxicity (MLCT), flowcytometry and polymerase chain reaction (PCR).

متن کاملComparison of a commercial real-time PCR assay, RealCycler® PJIR kit, progenie molecular, to an in-house real-time PCR assay for the diagnosis of Pneumocystis jirovecii infections.
We compared the RealCycler® PJIR kit (Progenie Molecular), available in Europe, to an in-house real-time PCR assay for the diagnosis of Pneumocystis jirovecii infections. Excellent agreement was found (concordance rate, 97.4%; Cohen's kappa, 0.918>0.8) showing that this commercial assay represents an alternative method for the diagnosis of P. jirovecii infections.
