NR-14848 is a preparation of lipoarabinomannan (LAM), also referred to as mannosylated lipoarabinomannan (ManLAM), derived from the cell wall of irradiated Mycobacterium tuberculosis, strain H37Rv. LAM possesses many biological activities including immunogenicity, induction of TNF and the release of other cytokines, and inhibition of antigen processing. The nonreducing termini of H37Rv LAM are extensively capped with mannose.

Each vial contains approximately 500 µg of lyophilized purified LAM from Mycobacterium tuberculosis, strain H37Rv. Lyophilized products may aggregate as a loose powder near the lid. Please take precautionary measures (such as tapping the bottom of the tube on the lab bench) to reduce escape of the reagent when opening the vial to reconstitute contents.

Note: LAM can be reconstituted in water. A 100 mM to 500 mM aqueous buffered salt solution, such as phosphate buffered saline, may also be used.
