Description

Interleukin-4 Rat Recombinant produced in E. coli is a single, non-glycosylated polypeptide chain containing 125 amino acids and having a molecular mass of 14kDa. The IL-4 is purified by proprietary chromatographic techniques.

Storage & Handling

Lyophilized Interleukin-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL4 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
