Formulation	Lyophilized from sterile 20mM Tris, 500mM Nacl, 10% glycerol, pH 7.4. 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background	Sorcin was originally identified in multidrug-resistant cells. It is a alcium-binding protein. Sorcin modulates excitation-contraction coupling in the heart, contributes to calcium homeostasis in the heart sarcoplasmic reticulum. Sorcin is overexpressed in the multi-drug resistant chinese hamster ovary cell line CHRC5 and a variety of multidrug-resistant tumor cell lines, but overexpression is not a sufficient or necessary condition for the acquisition of the multidrug-resistant phenotype.
