Recombinant Human SPINK4 protein(Met1-Cys86), His-tagged

• Cat.No.: SPINK4-770H
• Product Overview: Recombinant Human SPINK4 (NP_055286.1) (Met 1-Cys 86) was expressed in HEK293, fused with a polyhistidine tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Met1-Cys86
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant human SPINK4 consists of 71 amino acids and has a predicted molecular mass of 8 kDa. It migrates as an approximately 10 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 97 % 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.
