NR-19345, Mycobacterium leprae Monodeglycosylated PGL-I, is no longer available.

NR-19345 was produced by acid hydrolysis using 0.3 N HCl at 100°C for two hours, which leads to formation of multiple products and some unhydrolyzed PGL-I. Preparative TLC in ether:acetone (9:1, v/v) with scraping of individual bands and elution of specific components from silica gives monodeglycosylated PGL-I.

Each vial contains approximately 250 µg of dried monodyglycosolated PGL-I pooled from up to three different strains of M. leprae. Please refer to the Certificate of Analysis for information regarding the specific strains used in the production of each lot.

Note: Monodyglycosolated PGL-I is soluble in 2:1 chloroform methanol or 100% methanol or ethanol. NR-19345 is not soluble in aqueous buffers.
