BACKGROUND The speed and sensitivity of real-time polymerase chain reaction (PCR) have made it a popular method for the detection of microbiological agents in both research and clinical specimens. For the detection and genotyping of herpes simplex virus (HSV) in clinical specimens, real-time PCR has proven to be faster, more sensitive and safer than earlier methods which included isolation of t...

influenza a virus is now considered to be widespread in poultry and has demonstrated the ability to infect humans in iran. for laboratory diagnosis of these respiratory viruses, it is essential to have rapid methods, able to detect viruses in early stages of the infection in clinical specimens. the real-time reverse-transcription polymerase chain reaction n (rrt-pcr) assay has been established ...

PURPOSE RT-PCR technique has showed a promising value as pre-screening method for detection of mRNA containing abnormal ALK sequences, but its sensitivity and specificity is still discussable. Previously, we determined the incidence of ALK rearrangement in CNS metastases of NSCLC using IHC and FISH methods. MATERIALS We evaluated ALK gene rearrangement using two-step RT-PCR method with EML4-A...

  Objective(s): Adeno-associated virus type 2 (AAV2) vectors are widely used for both experimental and clinical gene therapy. A recent research has shown that the performance of these vectors can be greatly improved by substitution of specific surface-exposed tyrosine residues with phenylalanines. In this study, a fast and simple method is presented to generate AAV2 vector helper plasmids encod...

A one-step denaturing gradient gel electrophoresis (DGGE) strategy for the rapid detection of mutations in the factor VIII gene of haemophilia A patients is described. All coding (except the middle part of exon 14) and flanking intronic regions of the gene corresponding to approximately 6.6 kb were amplified in 27 fragments using four PCR programs. Heteroduplex formation was performed for each ...
