Description
This recombinant M.tb esxB protein is an E.coli expressed protein (Full Length of Mature Protein) with N-terminal 6xHis tag and its purity is 90%+ determined by SDS-PAGE. With the appropriate cDNA and PCR methods, esxB expression plasmids can be rapidly produced. which must undergo denaturation and folding cycle, can be recovered with more modest yields. Hence, using small-scale fermentations and laboratory-scale processing equipment, esxB proteins (or subdomains thereof) can usually be produced in sufficient quantities to initiate most studies including detailed structural determinations.which must undergo denaturation and folding cycle, can be recovered with more modest yields.

esxB, also called CFP-10, is a Mycobacterium tuberculosis secreted antigen that contributes to viral virulence and pathogenicity. CFP-10 and ESAT-6 forms a 1:1 heterodimeric complex that plays a critical role in the pathogenesis of tuberculosis (TB). Amanda Welin et al. has shown that the ESAT-6/CFP-10 complex induces a transient release of Ca2+ from intracellular stores in human neutrophils. CFP-10 rather than ESAT-6 was responsible for triggering the Ca2+ response, in a pertussis toxin-sensitive manner, implying the participation of a GPCR.
