Biological Activity
Description
IL-4 Protein, Porcine (CHO) is the prime anti-infalmmatory cytokine involves in cell proliferation, various gene expression and avert apoptosis in IL-4 expressing cells.
Background
The effect of IL-4 signaling is mediated through the IL-4 receptor alpha chain (IL-4Rα). Upon binding to its ligand, IL-4Rα dimerizes either with the common gamma chain (γc) to produce the type-1 signaling complex located mainly on hematopoietic cells, or with the IL-13 receptor alpha 1 (IL-13Rα1) to produce the type-2 complex, which is expressed also on non-hematopoietic cells[1].
Verified Bioactivity
The ED50 is <0.25 ng/mL as measured by TF-1 human erythroleukemic cells, corresponding to a specific activity of >4.0 × 106 units/mg.

Product Properties
Lyophilized powder
Lyophilized from a 0.22 μm filtered solution of PBS.
<0.2 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
