NR-14830 is a preparation of the cell wall fraction of Mycobacterium tuberculosis (M. tuberculosis), strain HN878, and contains proteins and non-protein compounds such as mAGP.

The culture was grown to late-log phase in glycerol-alanine-salts medium, washed with PBS pH 7.4, and inactivated by gamma irradiation. The bacilli were suspended at a concentration of 2 g/mL in PBS containing 8 mM EDTA, DNase, RNase, and a proteinase inhibitor tablet, and broken in a French Press pressure cell at 4°C. Unbroken cells were removed by low speed (3,000 x g) centrifugation. The cell wall was isolated by centrifugation at 27,000 x g for one hour and washed two times in PBS. The final cell wall pellet was suspended and dialyzed in 10 mM ammonium bicarbonate. The protein content was determined using the BCA protein assay.

Each vial of NR-14830 contains approximately 1 mg of cell wall fraction from M. tuberculosis, strain HN878 provided in 10 mM ammonium bicarbonate.
