One-step RT-PCR procedure without initial RNA extraction step is tested for laser microdissected tissue sample. Unfixed cryosections of liver and kidney tissue of male SD rats were cut using laser microdissection system and directly used as templates for RT-PCR study. To check the sensitivity, 5, 25, 125, and 625 hepatocytes were cut and put in PCR-tube. After DNase treatment and cDNA synthesis...

Real-time quantitative PCR (qRT-PCR) is one of the important methods for investigating the changes in mRNA expression levels in cells and tissues. Selection of the proper reference genes is very important when calibrating the results of real-time quantitative PCR. Studies on the selection of reference genes in goat tissues are limited, despite the economic importance of their meat and dairy pro...

Bonamia ostreae is an intrahaemocytic protozoan affecting Ostrea edulis. The parasite multiplies within haemocytes without being degraded and involves changes in cellular activities. Studies aiming at better understanding host response to a pathogen at the transcriptome levels are frequently based on the use of real time PCR assays, which require some reference genes. However, very few sequence...

objectives: human cytomegalovirus (cmv) is a major life-threatening pathogen for hematopoietic stem cell transplant recipients. specific tests are used for the diagnosis and monitoring of cmv infection in transplant patients. this study evaluates the performance of pp65 antigenemia and qualitative pcr assays for monitoring cmv in such patients. methods: we analyzed 179 clinical samples from 41...

viruses are the most common causes of aseptic meningitis. early detection, treatment and management of viral meningitis are priority. this study aimed to evaluate common viral meningitis in children referred to taleghani pediatrics hospital in gorgan, south east of caspian sea, iran. in this descriptive study csf and blood samples were taken from 40 children with negative bacterial culture who ...

Quantitative real-time PCR (qRT-PCR) is the most classical technique in the field of gene expression study. This method requires an appropriate reference gene to normalize mRNA levels. In this study, the expression stability of four frequently-used reference genes in epididymal white adipose tissue (eWAT), inguinal beige adipose tissue (iBeAT) and brown adipose tissue (BAT) from obese and lean ...
