EXPRESSION 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 کاملHuman combinatorial antibody libraries to hepatitis B surface antigen.
Human antibody Fab fragments that bind to hepatitis B surface antigen (HBsAg) were generated by using a recombinant phage surface-display expression system. Characterization of HBsAg-specific Fab fragments isolated from two vaccinated individuals reveals diversity in specificity of antigen binding and in the sequences of the complementarity-determining region. The sequence results show examples...

The preparations obtained by this method present the cells in random orientation, so that the profiles seen on electron microscopy fulfil the first criterion for morphometric analysis; quantitative studies can therefore be made of morphological changes that take place during the maturation of monocytes into macrophages. Reports have indicated that mononuclear phagocyte maturation is disordered ...
متن کاملIgE antibody against hepatitis B surface antigen in mice.
Hepatitis B surface antigen (HBs antigen) was examined for elicitation of IgE production by injection into mice. The Prausnitz-Küstner (PK)-type skin test in the rat was employed for detection of IgE antibody to HBs antigen, because no sufficient purified HBs antigen was available as the challenging antigen for the passive cutaneous anaphylaxis (PCA) test in rats. The positive PK test was consi...
متن کاملReactivation of hepatitis B virus with mutated hepatitis B surface antigen in a liver transplant recipient receiving a graft from an antibody to hepatitis B surface antigen– and antibody to hepatitis B core antigen–positive donor
BACKGROUND Fresh-frozen plasma (FFP) may contain antibodies to hepatitis B surface antigen (HBsAg, anti-HBs). These anti-HBs may lead to a misinterpretation of the actual hepatitis B immune status. Furthermore, they may not only confer protection against hepatitis B virus (HBV), but may also favor the selection of HBsAg mutants. CASE REPORT We report a case of de novo HBV infection in a HBV-n...
