GMP Recombinant Human IL4 Protein

Cat.No.: IL4-112HG
Product Overview: Recombinant Human IL4, His25-Ser153, was produced in E. coli using non-animal reagents in an animal-free facility under cGMP guidelines.
Source: E. coli
Species: Human
Form: Lyophilized from a 0.2 μm filtered solution in PBS.
Bio-activity: Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The ED50 for this effect is 0.05-0.2 ng/mL.
The specific activity of recombinant human IL-4 is approximately 2.9 x 10^4 IU/μg, which is calibrated against human IL-4 WHO International Standard (NIBSC code: 88/656).
Molecular Mass: Predicted Molecular Mass: 15.1 kDa
SDS-PAGE: 14 kDa, reducing conditions
N-terminal Sequence Analysis: Met-His25-Lys-(Cys)-Asp-Ile-Thr-Leu-Gln-Glu
Endotoxin: <0.10 EU per 1 μg of the protein by the LAL method.
Purity: >97%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Storage: Avoid repeated freeze-thaw cycles.
12 months, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution: Reconstitute at 100-200 μg/mL in PBS.
