Small molecule-selective channel required for the uptake of nutrients across the outer mycomembrane. Transports glycerol and glucose. Involved in sensitivity to M.tuberculosis growth inhibitory agrichemical 3,3-bis-di (methylsulfonyl) propionamide (3bMP1) . Transports maltose and lactose disaccharides. Involved in sensitivity to bactericidal thio-disaccharide T-6 compound (1,6-anhydro-3-deoxy-4-S- (2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl) -D-glycero-hexopyranos-2-ulose) . Transports extracellular trehalose, a component of the cell envelope, and trehalose analog, 6-azido trehalose (6-TreAz), which has antimycobacterial activity.

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
