NR-10049 is a recombinant form of the toxoid of Staphylococcal Enterotoxin B (SEB) with genetic mutations which render the protein non-toxic. NR-10049 contains a hexa-histidine tag near the N-terminus. The recombinant protein was expressed in Escherichia coli and purified by nickel affinity chromatography. NR-10049 has a theoretical molecular weight of approximately 30 kilodaltons.

The amino acid sequence of SEB from Staphylococcus aureus subsp. aureus, strain COL has been determined (GenPept: AAW37877). The crystal structure of SEB has been solved to 1.48 Å (PDB: 3SEB).

Each vial of NR-10049 contains approximately 1 mg of SEB toxoid in phosphate buffered saline (pH 7.4).

NR-10049 reacts with rabbit polyclonal antibody to SEB using western blot analysis.
