Human Recombinant IL-4 (from HEK293)

Protein/Peptide Type:
Recombinant
Source:
HEK293 cells
Species:
Human
Storage Conditions:
–20 °C
Endotoxin Content:
Less than 1.0 EU per μg by the LAL method.
Biological Activity:
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.; Measured by its binding ability in a functional ELISA. Immobilized Human IL-4 R alpha, His Tag (Cat. No. ILR-H5221) at 5 μg/mL (100 μL/well) can bind Biotinylated Human IL-4, Avitag,His Tag (Cat. No. IL4-H82E0) with a linear range of 1.95-15.6 ng/mL (QC tested).; Measured by its binding ability in a functional ELISA. Immobilized Human IL-4 R alpha, Fc Tag (Cat. No. ILR-H5253) at 5 μg/mL (100 μL/well)can bind Biotinylated Human IL-4, Avitag,His Tag (Cat. No. IL4-H82E0) with a linear range of 0.1-2 ng/mL (Routinely tested).; Biotinylated Human IL-4, Avitag,His Tag (Cat. No. IL4-H82E0) stimulates the proliferation of TF-1 human erythroleukemic cells. The ED50 for this effect is 1.19-2.64 ng/mL (Routinely tested).
