Product Details

Reactivity Species
Host Species
Purified Recombinant Human IL-3 (Accession # Q6GS87)
This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.3 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present.
Storage and Handling
The lyophilized antibody can be stored desiccated at -20°C to -70°C for up to twelve months. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid repeated freeze thaw cycles. No detectable loss of activity was observed after six months.

Applications and Recommended Usage?
Quality Tested by Leinco
Western Blotting: To detect Human IL-3 this monoclonal antibody can be used at a concentration of 1-2 µg/ml. This monoclonal antibody should be used in conjunction with compatible second-step reagents such as PN:M114 and a chromogenic substrate such as PN:T343. The detection limit for Human IL-3 is 5 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:I-185.
Other Applications Reported In Literature ?
Neutralization: This antibody is useful for neutralization of Human IL-3 bioactivity. The antibody dose required to neutralize 50% (ND50) of the biological activity of Human IL-3 (at 1.25 ng/ml) is 0.03 - 0.08 µg/ml.
Immunocytochemistry: Suitable for use at concentration of 8-25 µg/mL.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.


Clone 4806 recognizes an epitope on human IL-3.
IL-3 is a 17 kD pleiotropic cytokine and a member of a family of growth factors that sustains both the proliferation and the development of hematopoietic precursors. It also displays neurotrophic activity and is thought to be associated with neurologic disorders. Signal transmission is assured by high affinity binding to the IL-3 receptor (IL3RA). The receptor contains α and β subunits. IL-3 shares the β subunit with IL-5 and GM-CSF which explains their biological functional similarities. The IL-3/receptor complex induces JAK2/STAT5 cell signalization pathway and it can stimulate both the activation of gene expression and the suppression of apoptosis via transcription factor c‑myc and the Ras pathway, respectively. IL-3 fuels the differentiation of multipotent hematopoietic stem cells into myeloid progenitor cells or lymphoid progenitor cells (when in conjunction with IL-7). Together with other cytokines, including EPO, GM-CSF, and IL-6, IL-3 can stimulate proliferation of all cells in the myeloid lineage. The constitutive expression of IL-3 in some leukemia cell lines (as opposed to selective T-cell expression in response to specific impulses or antigens) is thought to fuel the development of the disease. Post-chemotherapy IL-3 application can promote regeneration of granulocytes and platelets. Furthermore, during high-dose chemotherapy, the combination of IL-3, GM-CSF and stem cell factor increases peripheral blood stem cells. IL-3 is thought to have therapeutic potential in lymphohematopoietic disorders and solid cancers.
