Large envelope, HBV-D (Cell-Free, His)

The large envelope protein has two conformations: “external” (Le-HBsAg) and “internal” (Li-HBsAg) . In its external state, it mediates viral attachment, initiates infection, determines species specificity, and promotes viral particle internalization via caveolin-mediated endocytosis. Large envelope Protein, HBV-D (Cell-Free, His) is the recombinant Virus-derived Large envelope protein, expressed by E. coli Cell-free , with N-10*His labeled tag.
