HCV has a high rate of replication with approximately one trillion particles produced each day in an infected individual. Due to lack of proofreading by the HCV RNA polymerase, the HCV has an exceptionally high mutation rate, a factor that may help it elude the host's immune response. Hepatitis C virus is classified into six genotypes(1-6) with several subtypes within each genotype. The preponderance and distribution of HCV genotypes varies globally. Genotype is clinically important in determining potential response to interferon-based therapy and the required duration of such therapy. Genotypes 1 and 4 are less responsive to interferon-based treatment than are the other genotypes (2, 3, 5 and 6).
The E.coli derived recombinant Biotin Labeled protein contains the HCV core nucleocapsid immunodominant regions, amino acids 2-119, having an MW of 22kDa. The protein is fused to a beta-galactosidase (114 kDa) at the N-terminus.
20mM Tris-HCl pH 8 and 8M urea.
HCV Core although stable at 4°C for 1 week, should be stored below -18°C.
Please prevent freeze thaw cycles.
Antigen in ELISA and Western blots, excellent antigen for detection of HCV with minimal specificity problems.
