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 کاملPitfall of hepatitis B surface antigen testing in a kidney transplant recipient presenting hepatitis B reactivation.
Diagnosis of hepatitis B virus (HBV) infection based on hepatitis B surface antigen (HBsAg) detection can be hampered in the setting of HBV reactivation in immunocompromized patients with prior serology indicating past cured infection, and can be associated with severe or fulminant and fatal hepatitis. We present a case of HBV reactivation in a renal transplant patient in whom HBsAg failed to b...
متن کاملCommunity-based hepatitis B screening: what works?
INTRODUCTION Chronic hepatitis B (CHB) affects over 350 million people worldwide and can lead to life-threatening complications, including liver failure and hepatocellular cancer (HCC). Modern antiviral therapies could stem the rising tide of hepatitis B-related HCC, provided that individuals and populations at risk can be reliably identified through hepatitis B screening and appropriately link...
متن کاملSurface protein mutations in chronic hepatitis B patients who received hepatitis B vaccine therapy
Objective (s):The aim of this study was to determine the correlation between vaccine therapy and appearance of mutations in hepatitis B surface antigen (HBsAg)-positive chronic hepatitis B virus (HBV) patients. Materials and Methods: 16 patients received the HBV vaccine and another 16 individuals from the control group did not. The surface gene was amplified and directly sequenced from samples...
متن کاملELISA for Quantitative Determination of Hepatitis B Virus Surface Antigen
Several studies have reported a good correlation between levels of serum hepatitis B virus surface antigen (HBsAg) and covalently closed circular DNA (cccDNA) before and after antiviral therapy. As a result, the quantification of HBsAg levels has attracted much attention in recent years as an important approach to evaluate viral activity. In this study, mAbs against HBsAg were generated and 9 m...
