NR-14820 is no longer available.  Mycobacterium tuberculosis, Strain CDC1551, Gamma-Irradiated Whole Cells is now available as NR-49099.

Mycobacterium tuberculosis (M. tuberculosis), strain CDC1551, was grown to late-log phase in glycerol-alanine-salts medium and inactivated by exposure to 2.4 mRads of ionizing gamma irradiation using a 137Cs source. Confirmation of inactivation was performed by Alamar Blue assay. A dose of 2.4 mRads of gamma irradiation kills M. tuberculosis to a 1020 degree of certainty while maintaining 93% to 95% of the biological activity of the enzymes. The bacilli are harvested by filtration and washed with PBS pH 7.4.

Each vial contains approximately 10 g of NR-14820 provided as a cell culture pellet.
