Catalog No.
HCV-205

Description :

Artificial mosaic polypeptide composite constructed from diagnostically relevant antigenic regions derived from the NS4 region of different HCV genotypes. The protein contains the fragments of the NS4 immunodominant region derived from 11 HCV genotypes. Hepatitis C Virus NS4 proteins are purified by proprietary chromatographic techniques.

Purification method:

Purified by proprietary chromatographic technique.

Purity:

Recombinant HCV NS4 is >95% pure as determined by 10% PAGE (coomassie staining) and RP-HPLC.

Formulation:

1mg/ml in 25mM Tris-HCl, 1mM EDTA, 1,5M urea and 50% glycerol.

Storage:

Recombinant HCV NS4 is shipped at ambient temperature. Upon arrival, Store at -20C.

Stability:

Recombinant HCV NS4 is stable 5 years frozen, One month in solution at room temperature.

Specificity:

Immunoreactive with sera of HCV-infected individuals.

Application:

Recombinant HCV NS4 Antigen may be used in ELISA and Western blots, excellent for detection of HCV with minimal specificity problems.

Usage:

This material is offered by ProSpec-TechnoGene for research, laboratory or further evaluation purposes.
