NR-14841 is a preparation of the TX-114 soluble proteins of Mycobacterium tuberculosis, strain H37Rv.

The culture was grown to late-log phase in glycerol-alanine-salts medium, washed with PBS and inactivated by gamma-irradiation. Cells were broken by French press in 4% triton X-114, partitioned at 37°C and centrifuged. The upper aqueous layer was removed and the process was repeated twice to extract the triton layer. The final triton layer was precipitated in acetone to remove the triton, and the resulting pellet was phenol-extracted, and then dialyzed in water. The protein content of the final product was then quantified using the BCA protein assay.

Each vial contains approximately 1 mg of NR-14841 in water provided as a frozen pellet.
