NR-49435 is a recombinant form of the secreted immunogenic protein Mpt64 (also referred to as mpb64) from Mycobacterium tuberculosis. The recombinant protein consists of the native protein sequence in addition to a hexa-histidine tag. Mpt64 was expressed in Escherichia coli and purified using standard chromatographic techniques followed by endotoxin removal procedures. Note: This protein is provided as a reference standard and should be ordered with the corresponding plasmid (pMRLB.12; NR-13273). Each vial of NR-49435 lot 70043621 contains approximately 275 ?g of lyophilized Mpt64 in 10 mM ammonium bicarbonate. Each vial of lot 70006290 contains approximately 1 mg of lyophilized Mpt64 in 10 mM ammonium bicarbonate. Note: NR-49435 is soluble in 100 mM to 500 mM aqueous buffered salt solutions, such as phosphate buffered saline. A 10 mM ammonium bicarbonate solution can also be used.
