ACROBiosystems Vibrio cholerae serotype O1 CTXB Protein, His Tag
Marque: ACROBiosystems CTB-V52E8-50UG
Informations supplémentaires : Poids : 0.00001kg
Description
Cholera enterotoxin subunit B (CTXB) is also known as cholera enterotoxin B chain, cholera enterotoxin gamma chain and choleragenoid. Vibrio cholerae O1 exists as two major serotypes, Inaba and Ogawa, which are associated with the O antigen of the lipopolysaccharide and are capable of unequal reciprocal interconversion. The B subunit pentameric ring directs the A subunit to its target by binding to the GM1 gangliosides present on the surface of the intestinal epithelial cells. CTXB can bind five GM1 gangliosides. Also, it has no toxic activity by itself.
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 13.5 kDa. The protein migrates as 18-22 kDa under reducing (R) condition (SDS-PAGE).Spécification
