| Form : |
Lyophilized from sterile 20mM MOPS,150mM NaCl, 0.05% CHAPS, PH7.0Please 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 : |
1. Measured by its binding ability in a functional ELISA. Immobilized human IL27-His at 10 μg/ml (100 μl/well) can bind human IL27RA-Fc, The EC50 of human IL27RA-Fc is 0.2-0.46 μg/ml.2. Measured in antiviral assays using HepG2 cells infected with vesicular stomatitisvirus(VSV). The ED50 for this effect is typically 23-92 ng/mL. |
| Molecular Mass : |
The recombinant human IL27 complex (IL27B & IL27A) consists of 450 amino acids after removal of the signal peptide and has a calculated molecular mass of 56 KDa as estimated in SDS-PAGE under reducing conditions. |
| Proteinlength : |
Met1-Lys229&Phe29-Pro243 |
| Endotoxin : |
< 1.0 EU per μg of the 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. |
