Assays for hepatitis B surface antigen (HBsAg) are the most frequently used tests to detect HBV infection. Vaccination for HBV can produce transiently detectable levels of HBsAg in patients.

Use the purifier to isolate the hepatitis B antigen produced by the yeast cells. The vaccine, once administered, will stimulate the immune system to attack the antigen (i.e., the protein coat).

Spontaneous loss of hepatitis B e antigen (HBeAg) followed by seroconversion to anti-HBe usually coincides with normalization of serum alanine aminotransferase (ALT) levels, reduction in HBV DNA ...
