Store at: -80°C or colder
Contributor: BEI Resources or NIH - TB Vaccine Testing and Research Materials Contract
Comments:
NR-31384 is no longer available.  HspX, Recombinant Protein Reference Standard from Mycobacterium tuberculosis, is now available as NR-49428.

NR-31384 is a recombinant form of the heat shock protein HspX (also referred to as a-crystalline) from Mycobacterium tuberculosis. The recombinant protein consists of the native protein sequence in addition to a hexa-histidine tag. HspX 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.15; NR-13274).

Each vial contains approximately 1 mg of lyophilized NR-31384 in 10 mM ammonium bicarbonate.

Note: NR-31384 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.
