Function

Mixed specificity lectin with anti-HIV activity. Binds to HIV envelope glycoproteins, including exterior membrane glycoprotein gp120, and inhibits viral entry into cells. Binding to gp120 is dependent on gp120 being glycosylated, and is inhibited by mannose, glucose and N-acetylglucosamine.

Product Specifications

Recombinant Griffithsia sp. Griffithsin (X31S) is a recombinant protein from Griffithsia sp. (strain Q66D336) (Red alga), expressed in E.coli, covering amino acids 1-121aa(X31S), with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 20.2kDa, purity Greater than 85% as determined by SDS-PAGE..
