|IL-3, MCGF, MGC79398, MGC79399, MULTI-CSF|
|A DNA sequence encoding the human IL3 (NP_000579.2) (Met 1-Phe 152) was expressed, fused with a polyhistidine tag at the C-terminus.|
|In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.|
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
|> 95 % as determined by SDS-PAGE|
|1. Measured in a cell proliferation assay using TF1 human erythroleukemic cells (Kitamura, T. et al. 1989 J. Cell Physiol. 140: 323.)
. The ED50 for this effect is typically 0.3-1.5 ng/ml
2. Measured by its binding ability in a functional ELISA . Immobilized human IL3 at 20 μg/ml (100 μl/well) can bind human IL3Ra with a linear ranger of 0.064-1.6 μg/ml. Immobilized human IL3 at 20 μg/ml (100 μl/well) can bind biotinylated human IL3Ra with a linear ranger of 0.32-1.6 μg/ml.
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant human IL3 consists of 143 amino acids and predicts a molecular mass of 16.5 kDa. It migrates as an approximately 19 kDa band in SDS-PAGE under reducing conditions.|
|Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.4|
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
IL3 (interleukin 3), also known as IL-3, is a potent growth promoting cytokine which belongs to the IL-3 family. IL3/IL-3 also belongs to the group of interleukins. Interleukins are produced by a wide variety of body cells. The function of the immune system depends in a large part on interleukins, and rare deficiencies of a number of them have been described, all featuring autoimmune diseases or immune deficiency. The majority of interleukins are synthesized by helper CD4+ T lymphocytes, as well as through monocytes, macrophages, and endothelial cells. They promote the development and differentiation of T, B, and hematopoietic cells. IL3/IL-3 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. IL3/IL-3 has been shown to also possess neurotrophic activity, and it may be associated with neurologic disorders.
