|Cat. No. :
|Product Overview :
||Recombinant Ag85B His-Tag fusion protein produced in E.Coli is a single, non-glycosylated polypeptide chain having a molecular mass of 30 kDa.
||Antigen 85B Mycobacterium Tuberculosis- is the most abundant protein exposed by M. Tuberculosis, as well as a potent immunoprotective antigen and a leading drug target. Ag85 induces strong T-cell proliferation and IFN-g secretion in most healthy individuals exposed to M. tuberculosis, in BCG-vaccinated mice and humans, whereas the antibody against Ag85 are more prevalent in active tuberculosis patients with decreased cellular immune response.
|Physical Appearance :
||Sterile Filtered lyophilized powder
||Greater than 90.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
||The protein was lyophilized with no additives.
||It is recommended to reconstitute the lyophilized Antigen-85B in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
||Ag85B although stable room temperature for 4 weeks, should be stored desiccated below -18℃. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
||Antigen 85B; Mycobacterium Tuberculosis major secretory protein Antigen 85B.
