Form : |
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. |
Bio-activity : |
Measured in a serum-free cell proliferation assay using MCF‑7 human breast cancer cells.The ED50 for this effect is typically 0.2-1 µg/mL. |
Molecular Mass : |
The recombinant human Insulin consists of 63 amino acids and predicts a molecular mass of 7.1 KDa. It migrates as an approximately 6 KDa band in SDS-PAGE under reducing conditions. |
Proteinlength : |
Phe25-Lys53 & Gly90-Asn110 |
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. |
