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.

溶解建议
Sterile Filtered lyophilized powder. The protein was lyophilized with no additives. It is recommended to reconstitute the lyophilized Antigen-85B in sterile 18MΩ-cm H2O not less than 100ug/ml， which can then be further diluted to other aqueous solutions.
保存建议
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.
