Recombinant Human TOP1 protein(Lys191-Phe765), His-tagged

• Cat.No.: TOP1-1078H
• Product Overview: Recombinant Human TOP1 (NP_003277.1) (Lys191-Phe765) was expressed in Insect Cells with a polyhistidine tag at the N-terminus.

Specification

• Species: Human
• Source: Insect Cells
• Tag: His
• Protein Length: Lys191-Phe765
• Form: Lyophilized from sterile 20 mM Tris, 200 mM NaCl, 20 % glycerol, pH 7.5. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant human TOP1 consists of 594 amino acids and predicts a molecular mass of 70.4 kDa.
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 90 % 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.
