Release of e antigen from a Dane particle-rich preparation of hepatitis B virus.
Tween 80 treatment of a Dana particle-rich pellet obtained from sera of a carrier with a hepatitis type B infection resulted in the release of e antigen.
متن کاملDemonstration of hepatitis B e antigen (HBeAg) in association with intact Dane particles.
Mild detergent treatment (0.1% Sarkosyl-0.1% beta-mercaptoethanol) of Dane particle-rich fraction from human serum resulted in the release of core particles together with HBe antigen activity when examined by the reversed passive haemagglutination method. Furthermore, when the core particles isolated by the above procedure were exposed to stronger detergent (1% Sarkosyl-0.1% beta-mercaptoethano...
متن کاملEXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE
The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...
متن کاملPlatelet aggregation by hepatitis B surface antigen-antibody complexes.
Platelet aggregation indicating antigen-antibody complex formation was observed when hepatitis B surface (HBs) antigen and antibody were mixed. Platelet aggregation titers were determined for serum specimens found positive by radioimmunoassay for either HBs antigen or HBs antibody. From these determinations, incidence of HBs antigen-antibody complexes was found to be higher in HBs antigen seraa...
متن کاملHepatitis B virus surface antigen (HBsAg) and antibody (anti-HBs) forming immune complexes in fulminant hepatitis.
This paper reports an unusual pattern of serological HBV markers and the presence of HBsAg/anti-HBs immune complexes in serum samples from two patients with fulminant hepatitis from the Brazilian Western Amazon Basin. The diagnosis was made by both serologic tests and demonstration of antigen/antibody complexes by transmission electron microscopy. Concurrent Delta virus superinfection is also d...
