Human IL-3 Protein

产品信息(Product Info)

Recombinant Human IL-3 Protein is expressed from E.coli without tag. It contains Ala20-Phe152.[Accession | AAC08706]

分子量大小(Molecular Weight)

The protein has a predicted MW of 15.09 kDa same as Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.


Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


-20 to -80°C for 12 months as supplied from date of receipt.
-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Human IL-3 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


The purity of Human IL-3 is greater than 95% as determined by SEC-HPLC.

Cell Based Assay

Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. The ED50 for this effect is 0.1 - 0.3 ng/mL.


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. This CSF induces granulocytes, macrophages, mast cells, stem cells, erythroid cells, eosinophils and megakaryocytes.
