| Product Name: |
Recombinant Human IL4 protein, GMP Grade |
| Product Overview: |
Recombinant Human IL4 protein GMP Grade(NP_000580) was expressed in E. coli. |
| Source: |
E. coli |
| Species: |
Human |
| Form: |
Lyophilized from sterile 50 mM Tris, 300 mM NaCl, pH 7.0, 5 % trehalose, 5 % mannitol and 0.01% Tween80. |
| Bio-activity: |
Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. The ED50 for this effect is 0.05-0.2 ng/mL. The specific activity of recombinant human IL-4 is approximately 1.4 x 10^4 IU/μg, which is calibrated against human IL-4 WHO International Standard (NIBSC code: 88/656). |
| Molecular Mass: |
The GMP recombinant human IL4 consisting of 130 amino acids and migrates with an apparent molecular mass of 15 kDa as predicted. |
| Endotoxin: |
Less than 0.01 EU per μg determined by the LAL method. |
| Purity: |
Greater than 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. |
