DNA based HLA typing is fast replacing conventional Microlymphocytotoxicity based method, which has been regarded as the gold standard. Many laboratories in Mumbai have already switched over to molecular methods, as the results are far superior. This study was undertaken to compare the results of generic molecular typing by sequence specific primers (SSP) with that by serology in our laboratory...

Molecular techniques such as spa typing and multilocus sequence typing use DNA sequence data for differentiating Staphylococcus aureus isolates. Although spa typing is capable of detecting both genetic micro- and macrovariation, it has less discriminatory power than the more labor-intensive pulsed-field gel electrophoresis (PFGE) and costly genomic DNA microarray analyses. This limitation hinde...

introduction: considering the role of hla matching in transplant outcome, the quality of hla-dr typing is clearly an important issue.in recent years serologic methods have been replaced with dna based typing methods.the main objective of this study was to compare hla-dr typing data obtained from existing serologic method with that obtained by the new pcr-ssp method. material and methods: fifty-...

We have developed a new procedure (Vir typing) for typing Streptococcus pyogenes, by amplifying the entire 5- to 7-kb variable vir regulon by long PCR. The amplified DNA is then cleaved with HaeIII and visualized by ethidium bromide fluorescence after agarose gel electrophoresis. A simple procedure for preparing DNA of sufficiently high quality from 96 samples was employed simultaneously. This ...

Introduction DNA typing has become widely accepted for the characterization of forensic biological evidence. The current genetic markers used, i.e., predominately short tandem repeat (STR) loci and to a lesser extent mitochondrial DNA (mtDNA), offer high levels of discrimination. In addition, the polymerase chain reaction (PCR) (1), the cornerstone of forensic DNA typing, provides a sensitivity...
