Monophosphoryl Lipid A from Salmonella minnesota R595
Monophosphoryl Lipid A (MPLA-SM) is extracted from lipopolysaccharide (LPS or endotoxin) produced by the Re mutant of a rough strain Salmonella minnesota R595.
MPLA-SM is provided as a clear, lyophilized lipidic film.
1 mg Monophosphoryl Lipid A (MPLA-SM)
MPLA-SM is shipped at room temperature.
Store at -20°C. Upon resuspension, prepare aliquots of MPLA and store at -20°C.
Product is stable 6 months at -20°C.
Avoid repeated freeze-thaw cycles.
Description
MPLA-SM is a potent activator of TLR4 with negligible TLR2 activity. MPLA-SM was extracted from LPS using treatment with acid and heat followed by chromatography. Preparations of natural MPLA, such as MPLA-SM, contain a mixture of 5, 6, and 7 acyl lipid A [1].
Note: Due to the intrinsic structural complexity of lipid A, some batch-to-batch variation may occur.
