NR-44101 is a preparation of mycobactin (MBT) derived from irradiated Mycobacterium tuberculosis (M. tuberculosis), strain H37Rv. Mycobactin, an iron-binding siderophore, is located in the cell wall where it facilitates the transport of iron to the interior of the cell. Mycobactin may also function as a growth factor in low-iron environments and has demonstrated a possible role in microbial virulence.

Each vial contains approximately 100 µg of dried mycobactin from M. tuberculosis, strain H37Rv.

Note: Mycobactin is soluble in chloroform:methanol (2:1). Chloroform or DMSO can also be used depending on the downstream application.
