Product Summary for Mouse IL-3 Quantikine ELISA Kit

The Quantikine Mouse IL-3 Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse IL-3 in cell culture supernates and mouse serum. It contains E. coli-expressed recombinant mouse IL-3 and antibodies raised against recombinant mouse IL-3. This Immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse IL-3 showed dose curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring mouse IL-3.

Background: IL-3

Interleukin-3 (IL-3) is a secreted cytokine that stimulates the proliferation and differentiation of pluripotent hematopoietic stem cells and various lineage-committed progenitors. It also regulates the activation of mature mast cells, basophils, eosinophils, and macrophages. It is produced by activated T cells, thymic epithelial cells, activated mast cells, keratinocytes, neurons, and astrocytes. IL-3 signals through a receptor complex that contains IL-3 R alpha/CD123 and the common beta chain which is also a component of the receptors for IL-5 and GM-CSF. Receptors for IL-3 are present on bone marrow progenitors, macrophages, mast cells, eosinophils, megakaryocytes, basophils, and various myeloid leukemic cells. Human IL-3 does not show activity on mouse cells.
