Polyclonal Goat Affinity Purified E
Hepatitis B surface antigen (HBsAg) is a serological marker on the surface of hepatitis B virus. It is a group of morphologically heterogeneous complex macromolecular structures found in the serum of patients with hepatitis B virus infection. Electron microscopy reveals three forms of HBsAg, 20nm spherical particles, tubular structures of variable lengths and a diameter of 20nm, and 40nm spherical "Dane" particles which are the hepatitis B virus. Purified HBsAg has a density of 1.20-1.21 g/ml. HBsAg usually contain protein, carbohydrate, and lipid. HBsAg particles carry the common determinant, a, as well as d or y and w or r subtype determinants, and are classified into the four major subtypes, adw, adr, ayw and ayr. Rare sera contain HBsAg particles with all four subtype determinants (adywr).
