Recombinant Human TCN2, His tagged

• Cat.No.: TCN2-429H
• Product Overview: Recombinant Human TCN2 (NP_000346.2) (Met 1-Trp 427), fused with a C-terminal polyhistidine tag, was produced in CHO Stable Cells.

Specification

• Species: Human
• Source: CHO
• Tag: His
• Protein Length: 1-427 a.a.
• Predicted N Terminal: Glu 19
• Form: Lyophilized from sterile PBS, pH 7.4.Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization.
• Molecular Mass: The secreted recombinant human TCN2 comprises 418 amino acids with a predicted molecular mass of 46.7 kDa. It migrates with the molecular weight of approximately 44 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 eu per μg of the protein as determined by the LAL method.
• Purity: >90 % as determined by SDS-PAGE
• Stability: Samples are stable for up to twelve months from date of receipt at -70oC.
• Storage: Store it under sterile conditions at -20oC~-70oC. 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. Centrifuge the vial at 4℃ before opening to recover the entire contents.
