was awarded the Nobel prize in Chemistry along with Michael Smith for his work on PCR2. The PCR is commonly carried out in a reaction volume of 10-200 μl in small reaction tubes (0.2-0.5 ml volumes) in a thermal cycler. The thermal cycler heats and cools the reaction tubes to achieve the temperatures required at each step of the reaction. Many modern thermal cyclers make use of the Peltier effe...

In this short note, we present the results of a case study for monitoring the whole polymerase chain reaction (PCR) process (all steps) with a glass fiber fluorometer that was described in a former publication. To utilize this fluorometer, which was originally constructed for a PCR machine with three thermostating devices, a new thermostating device has been developed: the glass fiber matrix is...

Polymerase chain reaction (PCR) is an in vitro technique to synthesize large quantities of a given DNA molecule that separates the DNA into two complementary strands, uses a peltier heat pump to quickly heat and cool the DNA and uses the Taq polymerase for the synthesis of DNA. Taq is a bacterium that lives by volcanic sulfer jets at the bottom of the ocean where the temperature is very high. F...

background human papillomavirus (hpv) is associated with various benign and malignant lesions including genital condyloma and anogenital cancer. the presence of hpv-dna was studied in archival biopsies of high- and intermediate-risk lesions for cervical carcinoma in women referred to mirza hospital in tehran. patients and methods totally, 105 iranian archived biopsies collected during february ...
