Interleukin-3 Rat Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 140 amino acids and having a molecular mass of 16 kDa. The IL-3 is purified by proprietary chromatographic techniques.
Interleukin-3 is a pleiotropic cytokine produced primarily by activated T cells. IL-3 is thoµght to function via specific cell surface receptors to stimulate the proliferation, differentiation and survival of haematopoietic cell lines. IL-3 has also been shown to affect the functional activity of a variety of other cell types including mast cells, eosinophils, megakaryocytes and basophils.
Sterile Filtered White lyophilized (freeze-dried) powder.
Lyophilized from a 1mg/ml solution without any additives.
It is recommended to reconstitute the lyophilized Interleukin 3 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Interleukin-3 althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL3 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.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ser-Asp-Arg-Gly.
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
The ED50= 3-10 ng/ml corresponding to a specific activity of 100,000-333,334IU/mg determined by the dose dependent proliferation of murine NFS-60 cells.
