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).
Recombinant HCV core protein genotype 1b produced in E.Coli, comprised of the large core peptide containing 169 a.a., fused to a 6xHis tag at C-terminus, having a total Mw of 25.4kDa and pI of 11.02. Recombinant HCV core protein genotype 1b was purified by proprietary chromatographic techniques.
Sterile filtered solution containing Phosphate saline buffer, 50mM arginine and 1M urea.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
