S100 calcium binding protein B (S100B), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure, and performing cell based assays. It can also be used as an immunogen, as a protein standard, or in other research applications.

This recombinant protein was expressed from a DNA sequence encoding the human S100B (NP_006263.1) (Ser 2-Glu 92) fused to the Fc region of human IgG1 at the N-terminus.

Activity: Measured in a functional ELISA:
1. Measured by its ability to bind mouse S100A1.
2. Measured by its ability to bind TP53.

Formulation: Lyophilized in 100 mM Gly, 10 mM NaCl, 50 mM Tris, pH 7.5, 5% Mannitol, 5% Trehalose, 0.02% Tween-80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.

This protein is manufactured by SINO Biological.
