Abstract:
The production of conjugate vaccines within an E. coli (Escherichia coli) host provides an inexhaustible supply without the need for culture of pathogenic organisms. The machinery for expression of glycan and acceptor protein, as well as the coupling enzyme, are all housed within the E. coli chassis, meaning that there are no additional steps required for individual purification and chemical conjugation of components. In addition, there are far fewer purification steps necessary to obtain a purified glycoconjugate for use in vaccine testing. Here we describe production and purification of a HIS-tagged Campylobacter jejuni AcrA protein conjugated to Streptococcus pneumoniae serotype 4 capsule.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
