NR-14860 is a preparation of α-crystallin derived from the whole cell lysate of irradiated Mycobacterium tuberculosis (M. tuberculosis), strain H37Rv. M. tuberculosis whole cell lysate was extracted with 0.1% n-octylthioglucoside and fractionated by isoelectric focusing. Fractions containing 16 kDa proteins were cleaned by size exclusion chromatography and dialyzed against 10 mM ammonium bicarbonate.

Each vial contains approximately 100 µg of lyophilized α-crystallin in 10 mM ammonium bicarbonate.

Note: NR-14860 is soluble in 100 mM to 500mM aqueous buffered salt solutions, such as phosphate buffered saline. A 10 mM ammonium bicarbonate solution can also be used.
