IL-3 Protein, Human (HEK293, His)

Cat. No.: HY-P70765
Handling Instructions

IL-3 Protein, Human (HEK293, His) is a multipotent hematopoietic growth factor that can control blood formation. IL-3 Protein, Human (HEK293, His) is a recombinant human interleukin-3 (rhIL-3) expressed in HEK 293 cells with a His tag. rhIL-3 is also a weak inflammatory mediator. rhIL-3 can be used to improve states of hematopoietic failure[1].

AA Sequence



Greater than 95% as determined by reducing SDS-PAGE.

Biological Activity
The cell proliferation assay using TF-1 human erythroleukemic cells has an ED50 value of 0.3-1.5 ng/mL.

Lyophilized powder.


Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.


It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

Storage & Stability

Stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.


Room temperature in continental US;may vary elsewhere.


IL-3 has growth- and differentiation inducing potential on cells of the erythroid, granulocyte-macrophage (GM), megacaryocyte, and mast-cell lineage in vitro.
In addition IL-3 enhances the function of mature myeloid effector cells by stimulating monocyte- and eosinophil-mediated phagocytosis and antibody-dependent cellular cytotoxicity (ADCC), monocyte M-CSF receptor expression, tumor necrosis factor (TNF) and M-CSF synthesis, and basophil production of intracellular histamine and its release in response to complement factor C5a.
Thus, IL-3 may serve as a recruitment factor for activated inflammatory cells in states of increased demand, rather than being a major regulatory element in steady-state hematopoiesis[1].
