Active Recombinant Human GH1 protein

Specification :
| Source : E. coli | Species : Human | Tag : N/A | 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 by its ability to promote proliferation of INS-1 cells.The ED50 for this effect is 0.2-1 ng/mL. | Molecular Mass : The recombinant human GH1 consists 191 amino acids and predicts a molecular mass of 22.1 kDa. | Protein Length : Phe27-Phe217 | 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°CStore 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.
