Form/Format
Supplied as a lyophilized powder without additives. Reconstitute in sterile ddH2O to 100ug/ml, which can then be further diluted to other aqueous solutions.
Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Asp-Thr-His-Arg.
Biological Activity
Murine IL-3 is fully biologically active when compared to standard. The ED50 as determined by the dose-dependent stimulation of murine M-NFS-60 cells is < 0.05 ng/ml, corresponding to a Specific Activity of 2 x 107 IU/mg.
Protein Content
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.154 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of Murine IL-3 as a Reference Standard.

Preparation and Storage
Lyophilized powder may be stored at 4 degree C for short-term only. Reconstitute to nominal volume by adding sterile dH2O, 0.1% BSA or HSA and store at -20 degree C. Reconstituted product is stable for 12 months at -20 degree C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.

NCBI Description
The protein encoded by this gene 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. [provided by RefSeq]
Uniprot Description
Function: Granulocyte/macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages.This CSF induces granulocytes, macrophages, mast cells, stem cells, erythroid cells, eosinophils and megakaryocytes.
Subunit structure: Monomer.
Subcellular location: Secreted.
Tissue specificity: Activated T-cells, mast cells, natural killer cells.
Sequence similarities: Belongs to the IL-3 family.

Product Notes
The IL3 il3 (Catalog #AAA650633) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: The sequence of the first five N-terminal amino acids was determined and was found to be Met-Asp-Th r-His-Arg. It is sometimes possible for the material contained within the vial of "Interleukin 3, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
