Recombinant Human Interleukin 3 (Colony-Stimulating Factor, Multiple)

• Cat.No.: IL3-275H
• Product Overview: Recombinant Human Interleukin-3 produced inSaccharomycescerevisiae is a single, glycosylated polypeptide chain containing 133 amino acids and having a molecular mass of 15000 Dalton. The recombinant human IL-3 migrates as a broad band between 15 and 22 kDa in SDS-PAGE due to post-translation modifications, in particular glycosylation.

Specification

• Species: Human
• Source: S.Cerevisiae
• Tag: Non
• Description: IL3 is a potent growth promoting cytokine. This cytokine is capable of supporting the proliferation of a broad range of hematopoietic cell types. It is involved in a variety of cell activities such as cell growth, differentiation and apoptosis. This cytokine has been shown to also possess neurotrophic activity, and it may be associated with neurologic disorders.

• Physical Appearance: Sterile Filtered white lyophilized (freeze-dried) powder.
• Formulation: Lyophilized from a concentrated (1mg/ml) solution in water containing 20mM Phosphate buffer pH-6.3.
• Purity: Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
• Solubility: 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.
• Biological Activity: The ED50 of IL-3 is typically 0.1- 0.4 ng/ml as measured in a cell proliferation assay using the human growth factor dependent TF-1 cell line.
• Stability: Lyophilized Interleukin-3 although 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.
