Glycopeptide Composition of Hepatitis B Surface Antigen

open access: yesJournal of General Virology, 1980
Three major polypeptides of hepatitis B surface antigen (HBsAg), with mol. wt. 22,000 (p22), 27,000 (p27) and 68,000 (p68), were separated by preparative SDS-PAGE. These three peptides as well as intact HBsAg were found to have almost identical amino acid compositions and carbohydrate was detected in p27 and p68 by PAS staining. Papain treatment of p68

A new group of hepadnaviruses naturally infecting Orangutans (Pongo pygmaeus) [PDF]

open access: yes, 1999
A high prevalence (42.6%) of hepatitis B virus (HBV) infection was suspected in 195 formerly captive orangutans due to a large number of serum samples which cross-reacted with human HBV antigens.

Antiviral treatment alters the frequency of activating and inhibitory receptor-expressing natural killer cells in chronic Hepatitis B virus infected patients [PDF]

open access: yes, 2012
Natural killer (NK) cells play a critical role in innate antiviral immunity, but little is known about the impact of antiviral therapy on the frequency of NK cell subsets.

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Chemiluminescent Optical Fiber Immunosensor Combining Surface Modification and Signal Amplification for Ultrasensitive Determination of Hepatitis B Antigen

open access: yesSensors, 2020
Optical fiber based immunosensors are very attractive for biomarker detection. In order to improve the sensor response, we propose a promising strategy which combines porous-layer modification of the fiber surface and streptavidin-biotin-peroxidase nano ...

Carbohydrate Composition of Hepatitis B Surface Antigen

open access: yesJournal of General Virology, 1977
The content and composition of carbohydrate in hepatitis B surface antigen HBsAg) were clarified by gas chromatography. A value of 75-8 microgram carbohydrate per mg of protein was obtained. The main components were N-acetylglucosamine, mannose, galactose and sialic acid and the minor one was fucose. No N-acetyl-galactosamine was detected.
