Description : | Interleukin-3 (IL-3) is an interleukin, a type of biological signal (cytokine) which is encoded by the IL-3 gene located on chromosome 5 and produced primarily by activated T cells beside human thymic epithelial cells, activated murine mast cells, murine keratinocytes and neurons/astrocytes. The protein acts in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. The human IL-3 reported to be a monomer, as it is known, contains 133 amino acids residues which is a single non-glycosylated polypeptide. Specifically, human and murine IL-3 share low homology and it does not show activity on murine cells. |

Purity : | >96% by SDS-PAGE and HPLC analysis. |
Storage : | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution. |
Reconstitution : | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤-20 centigrade. Further dilutions should be made in appropriate buffered solutions. |

Q&As (16)
Ask a questionIn vitro, IL-3 can induce differentiation and proliferation of myeloid lineage cells and is distinguished from GM-CSF by the relative increase in production of platelets, basophils, and mast cells.
Although effective, IL-3 appears to present no therapeutic advantages compared to G-CSF and GM-CSF, and in direct comparison studies, IL-3 led to a considerably higher rate of adverse events than either of the other cytokines.
mice deficient in both bc and IL-3 show the same phenotype as the bc-deficient mice, conclusively demonstrating that, for the most part, the GM-CSF/IL3/IL5 family is not essential for steady-state production of myeloid cells
Unlike in humans, murine IL-3 has a second b chain receptor, bcIL3, which bears 91% homology to the bc chain.
Knockout mice were also reported with surprisingly limited phenotypes. Despite the ability of the three cytokines to stimulate hematopoiesis, mice functionally deficient in all three cytokinesdisplay normal circulating levels of granulocytes, monocytes, and basophils.
non-hematopoietic (e.g., epithelial cells, and fibroblasts) cell subsets can also produce il-3.
Such as allergic inflammation and parasitic infestation.
IL-3 can regulate the survival of basophil granulocytes and cytokine production through autocrine, so as to achieve the purpose of treating allergic diseases.

E.g., lymphocytes,epithelial cells, and fibroblasts
Yes, there are some completed clinical trials on IL3 results, but the specific results need to refer to the relevant research papers.
This protein can promote stem cell proliferation and differentiation during hematopoietic process, thus increasing the production of different types of blood cells.
In general, the IL3 has relatively few side effects, but some unpleasant symptoms such as fever, headache and nausea may occur.
IL3 can regulate the body's immune response and the function of immune cells, and plays an important role in immune regulation.
IL3 generally have good solubility and stability, making them easier to handle during drug preparation and storage.
The study of IL3 is ongoing, including its application in the development of therapeutic drugs, as well as in combination therapy with other immune molecules.
