Description of Porcine IL-4
Interleukin-4 Porcine Recombinant produced in E. Coli is a non-glycosylated monomer chain containing 110 amino acids and having a molecular mass of 12.7kDa.
The ED50, as determined by TF-1 cell proliferation is 0.504ng/ml corresponding to a specific activity which is 2.0 x 106 units/mg.
It is recommended to reconstitute the lyophilized IL-4 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized IL-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-4 should be stored at 4°C between 2-7 days and for future use below -18°C. Please avoid repeated freeze-thaw cycles.
