• Cat.No.: CSTA-226H
• Product Overview: Recombinant Human CSTA (P01040) (Ile 2-Phe 98) was expressed in E. coli with a polyhistide tag at the N-terminus.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Ile2-Phe98
• Form: Lyophilized from sterile 50mM Tris, 1mM EDTA, pH 7.8. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant human CSTA consisting of 108 amino acids and has a calculated molecular mass of 12.4 KDa. It migrates as an approximately 14 kDa band in SDS-PAGE under reducing conditions.
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
