manufacturing new hepatitis b virus vaccines, specifically by the use of nanoparticles, is of high global interest. in this paper, a new biocompatible and biodegradable structure of nano-sized hepatitis b virus’ surface antigen (hbsag) was generated by conjugation with dendrimers, a low cost biodegradable and biocompatible polymer. the physicochemical properties of the conjugate were characteri...

Bacterial conjugation, the transfer of single stranded plasmid DNA from donor to recipient cell, is mediated through the type IV secretion system. We performed conjugation assays using a transmissible artificial plasmid as reporter. With this assay, conjugation in Agrobacterium fabrum was modulated by the phytochromes Agp1 and Agp2, photoreceptors that are most sensitive in the red region of vi...

Manufacturing new Hepatitis B virus vaccines, specifically by the use of nanoparticles, is of high global interest. In this paper, a new biocompatible and biodegradable structure of nano-sized hepatitis B virus’ surface antigen (HBsAg) was generated by conjugation with dendrimers, a low cost biodegradable and biocompatible polymer. The physicochemical properties of the conjugate were characteri...

UNLABELLED Conjugation in bacteria is the contact-dependent transfer of DNA from one cell to another via donor-encoded conjugation machinery. It is a major type of horizontal gene transfer between bacteria. Conjugation of the integrative and conjugative element ICEBs1 into Bacillus subtilis is affected by the composition of phospholipids in the cell membranes of the donor and recipient. We foun...
