IL3, Murine 2 ug


IL3, Murine

(Recombinant Murine Interleukin 3 IL-3, Mast-cell Growth Factor, MCGF, Multi-CSF, P-cell Stimulating Factor)

Purity: >98% by SDS-PAGE and HPLC analyses

Source: Escherichia coli

Interleukin 3 is a pleiotropic factor produced primarily by activated T cells that can stimulate the proliferation and differentiation of pluripotent hematopoietic stem cells as well as various lineage committed progenitors. In addition, IL3 also affects the functional activity of mature mast cells, basophils, eosinophils and macrophages. Because of its multiple functions and targets, it was originally studied under different names; including mast cell growth factor, P-cell stimulating factor, burst promoting activity, multicolony stimulating factor, thy-1 inducing factor and WEHI-3 growth factor. In addition to activated T cells, other cell types can also produce IL3; such as human thymic epithelial cells, activated murine mast cells, murine keratinocytes and neurons/astrocytes. At the amino acid sequence level, mature human and murine IL3 share only 29% sequence identity. Consistent with this lack of homology, IL3 activity is highly species-specific and human IL3 does not show activity on murine cells..

rMuIL3 General Information
Amino Acid Sequence (140 aa):

The sample should be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Reconstituted solutions are stable for up to one week at 2-8°C. Stock solutions should be aliquoted and stored at -80°C. Further dilutions should be made in appropriate buffered solutions containing BSA or serum, and 1 µg/ml heparin sulfate.

The lyophilized sample is stable at 2-8°C, but should be kept desiccated at -20°C for long term storage. The reconstituted sample can be apportioned into working aliquots and stored -80°C for maximal stability. Avoid repeated freeze/thaw cycles.
