It is a hydrolysis probe which bear a reporter dye, often fluorescein (FAM) at its 5’ end and a quencher tetramethylrhodamine (TAMRA), attached to the 3’ end of the oligonucleotide. Advantages of qRT-PCR 1. The principle and application of new PCR Technologies. PCR or Polymerase Chain Reaction is a technique used in molecular biology to create several copies of a certain DNA segment. The polymerase chain reaction can be used to amplify both double and single stranded DNA. Variations of PCR Single Cell PCR It is now possible to amplify and examine minute quantities of rare genetic material, the limit of this exploration being the single cell. In microbiology and molecular biology, for example, PCR is used in research laboratories in DNA cloning procedures, Southern blotting, DNA sequencing, recombinant DNA technology, to name but a few. It is technically difficult to amplify targets >5000 bp long. PCR helps in varied applications dealing with infectious diseases through means like: detecting infections earlier, screening the donated blood directly for the virus, testing of the newborns against any existing virus and immediate quantifying of the effects of any therapy. Edited by: Ali Samadikuchaksaraei. Because both strands are copied during PCR, there is an exponential increase of the number of copies of the gene. HE polymerase chain reaction (PCR) is a power- ful technique allowing the enzymatic amplifica- tion of specific regions of DNA without utilizing con- ventional cloning procedures. PCR applications (e.g. Rapid cycling times (1 hour). The ease with which it can be done, the relatively low cost, and it’s unique combination of specificity and sensitivity coupled with great flexibility has led to a true revolution in genetics.
