The real-time polymerase chain reaction (RT-PCR), also called quantitative real-time polymerase chain reaction (QRT-PCR) or kinetic polymerase chain reaction (kPCR), is a technique used to simultaneously quantify and amplify a DNA molecule. It is used to determine whether a specific DNA sequence is present in the sample; and if it is present, the number of copies in the sample. It is the real-t...

during 2009-10, real time rt-pcr and conventional rt-pcr techniques used for detecting btvs rna in 310 blood samples. for real time and gel based rt-pcr segment-1 and segment-10 selected as conserve genes to search any btv strains. using these methods, 58 (%18.7) and 14 (%4.5) positive samples were detected among the clinically suspected sheep. sensitivity of both molecular techniques evalua...
