The Mouse Interleukin-3 (Ms IL-3) ELISA quantitates Ms IL-3 in mouse serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Ms IL-3.
Principle of the method
The Mouse IL-3 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, binding to the target on a different epitope from the capture antibody. A conjugated enzyme has been incorporated into the assay. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.
Interleukin 3 (IL-3), also called Mast Cell Growth Factor (MCGF), Multi-Colony Stimulating Factor (multi-CSF), or Eosinophil-CSF (E-CSF), is produced by activated T cells, mast cells and eosinophils. IL-3 is a hematopoietic growth factor that stimulates colony formation of erythroid, megakaryocyte, neutrophil, eosinophil, basophil, mast cell and monocytic lineages. Most of these functions are enhanced or dependent on co-stimulation with other cytokines. Human and mouse IL-3 share only 29% sequence identity at the amino acid level. The bioactivity of IL-3 is highly species specific. For example, human IL-3 has no activity on mouse cells. IL-3 is a potent growth promoting cytokine. IL-3 is capable of supporting the proliferation of a broad range of hematopoietic cell types, and is involved in a variety of cell activities such as cell growth, differentiation and apoptosis. IL-3 has been shown to also possess neurotrophic activity, and it may be associated with neurologic disorders.
