Onchocerca volvulus OV16 protein, GST Tag

The OV16 antigen, localizes to the hypodermis, cuticle, and uterus of female O. volvulus is regarded as a highly sensitive and specific antigen for detection of IgG4 in people with prior exposure to onchocerciasis. It has an open reading frame that encodes a 152- amino acid polypeptide containing a 16-amino acid putative signal peptide. Enzyme-linked Immunosorbent Assay serological testing of OV-16 antigen is a diagnostic tool for determining effective elimination of the parasite.

This protein carries a GST tag at the N-terminus. The protein has a calculated MW of 46.8 kDa. The protein migrates as 45 kDa under reducing (R) condition (SDS-PAGE) .

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.
