The hepatitis B surface antigen (HBsAg) is most frequently used to screen for the presence of this infection. It is the first detectable viral antigen to appear during infection. However, early in an infection, this antigen may not be present and it may be undetectable later in the infection as it is being cleared by the host.
应用类型
ELISA
免疫原
HBsAg antibody was raised in mouse using highly purified hepatitis B surface antigen as the immunogen.
