hep-1

HEP-1 (Human ezrin peptide (324-337)) is an orally active peptide with anti-HIV properties, shown to enhance antibody titers after hepatitis B vaccination. Its potential in viral infection treatment warrants further investigation [1].

Collagen type IV alpha1 (531-543) is a protein that in humans is encoded by the COL4A1 gene on chromosome 13. It is ubiquitously expressed in many tissues and cell types. COL4A1 is a subunit of type IV collagen and plays a role in angiogenesis.

Hepatitis B Virus Receptor Binding Fragment (hepatitis B peptide 4980), a synthetic peptide analog, specifically binds to Hep G2 cells and is a potential immunogen expected to induce protective antibodies through the attachment blockade pathway of virus neutralization [1] [2].
