NR-49424 is a recombinant form of the early secretory antigenic target protein, ESAT-6. The protein sequence consists of amino acid residues 1 to 103 including a hexa-histidine tag at the C-terminus. The recombinant protein was expressed in Escherichia coli BL21 (DE3) pLysS cells and purified by immobilized-metal affinity chromatography. ESAT-6 has a theoretical molecular weight of approximately 11 kDa.

Note: This protein is provided as a reference standard and should be ordered with the corresponding plasmid (pMRLB.7; NR-50170).

Each vial contains approximately 1 mg of lyophilized ESAT-6 in 10 mM ammonium bicarbonate.

Note: NR-49424 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.
