The AMPIPROBE^® HCV assay kit is a quantitative reverse transcription polymerase chain reaction (RT-qPCR) assay for the quantitative detection of human hepatitis C virus (HCV) RNA in plasma or serum. The proprietary primer mix included in the kit is specific for HCV genotypes 1 through 6. The kit includes titered high, medium, and low HCV controls which enable virus quantitation in IU/mL. In addition, the kit contains an extraction control to ensure proper sample nucleic acid extraction.

Enzo's AMPIPROBE^® technology incorporates probe detection technology in primer design. It employs a combination of fluorescent reporter-labeled primers and quencher-labeled primers to amplify DNA, akin to traditional PCR. When free in solution, fluorescent primers generate a signal. However, as the primers are incorporated into amplified DNA, the quencher and the fluorophore are brought within close proximity and exhibit Forster resonance energy transfer (FRET). This causes a logarithmic decay of signal with respect to the number of amplification cycles of DNA. Once the signal decays to a defined threshold, a value is generated with respect to the corresponding cycle. The threshold cycle is indicative of the amount of target RNA or DNA in the sample.

Scientific Background:	HCV is a single-stranded, positive sense RNA virus with a genome of approximately 9,500 nucleotides coding for 3,000 amino acids. HCV exists as six closely related, yet distinct genotypes. HCV infects about 4 million individuals in the US and about 170 million individuals worldwide. Acute HCV infection will most often progress to chronic infection. If left untreated, the disease may progress to liver fibrosis, cirrhosis, decompensated liver disease, and death. In addition, 25% of all cirrhotic patients will also develop hepatocellular carcinoma. Quantifying HCV RNA is a well-established method for measuring baseline viral loads and response to treatment. HCV RNA can be detected in plasma or serum by extraction and amplification of nucleic acid. The AMPIPROBE^® HCV assay kit uses a novel probe system to accurately quantify HCV RNA.
