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 کاملHepatitis Be antigen and antibody in hepatitis B surface antigen positive blood donors.
In a study of 105 asymptomatic HBsAg positive blood donors, 9 (8.6%) were found to have HBeAg, 38 (36.2%) anti-HBe, and the remaining 58 (55.2%) neither marker detectable by gel diffusion. There was no correlation between HBeAg/anti-HBe status and HBsAg sub-types, Glm allotypes, the presence of anti-Gm, red cell antibodies, or rheumatoid factor. Rheumatoid factor activity could be removed from ...
متن کاملA study of the reference of pronoun ‘this’ in “All praise is due to Allah who guided us to this and we would not have found the way had it not been that Allah had guided us”
We encounter with some pronouns in the Holy Quran that are with no reference. Of course this makes mind search for their reference with regard to the verses’ meaning and intention, otherwise it views as subjective interpretation of Quranic text. One of these cases is the pronoun ‘this’ in (7: 43) in which anyone who is in Paradise says: “All praise is due to Allah who gu...
متن کاملKinetics of Hepatitis B Surface Antigen Level in Chronic Hepatitis B Patients who Achieved Hepatitis B Surface Antigen Loss during Pegylated Interferon Alpha-2a Treatment
BACKGROUND Hepatitis B surface antigen (HBsAg) loss/seroconversion is considered to be the ideal endpoint of antiviral therapy and the ultimate treatment goal in chronic hepatitis B (CHB). This study aimed to assess the patterns of HBsAg kinetics in CHB patients who achieved HBsAg loss during the treatment of pegylated interferon (PEG-IFN) α-2a. METHODS A total of 150 patients were enrolled, ...
متن کاملA cellular protein which binds hepatitis B virus but not hepatitis B surface antigen.
The envelope of hepatitis B virus (HBV) consists of three related proteins known as the large (L), middle (M) and small (S) hepatitis B surface antigens (HBsAg). L-HBsAg has a 108-119 amino acid extension at the N terminus compared with M-HBsAg and contains the preS1 sequence of the HBV envelope. Previous research has identified this region as the likely virus attachment protein which is though...
