Product details:
Human IL-5 Receptor alpha ELISA kit (ab283549) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Human IL-5 Receptor alpha protein in human serum, plasma and cell culture supernatant samples. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human IL-5 Receptor alpha with 20.55 pg/mL sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Human IL-5 Receptor alpha is a heterodimeric cytokine receptor. Binding of IL-5 activates the beta subunit. It is expressed on eosinophils and basophils and is a target of the drug benralizumab, which leads to almost complete depletion of eosinophils. Benralizumab treatment has been demonstrated in clinical trials to reduce asthma reactions.

IL-5RA also known as the interleukin-5 receptor alpha chain or IL-5 receptor is a protein with a critical role in the immune system. It is also referred to as CD125 or CaL40. The protein has an approximate mass of 52 kDa and is expressed mainly on eosinophils and basophils which are types of white blood cells involved in immune responses. The IL-5RA forms a part of the IL-5 receptor complex which also includes a beta chain responsible for signal transduction.
Biological function summary
IL-5RA plays an important role in the growth differentiation and activation of eosinophils. The protein forms part of the IL-5 receptor complex which binds to the cytokine IL-5 initiating a signaling cascade that results in these processes. Through its interaction with IL-5 IL-5RA influences the survival and function of eosinophils cells critical for responses against parasitic infections and in allergic reactions.
Pathways
IL-5RA is fundamental in the JAK-STAT signaling pathway. This pathway is significant as it facilitates the transduction of extracellular cytokine signals into cellular responses impacting the growth and activity of eosinophils. The IL-5 receptor complex is associated with other cytokine receptors through this pathway involving proteins such as JAK2 and STAT5 which play essential roles in the activation of downstream signaling events and cellular responses.
IL-5RA is linked with asthma and eosinophilic esophagitis conditions characterized by an abnormal proliferation and activation of eosinophils. In asthma for example the increased activity of IL-5RA leads to elevated levels of eosinophils contributing to airway inflammation and hyperresponsiveness. IL-5RA also connects with other proteins like IL-5 itself serving as a therapeutic target in treatments aimed at regulating excessive eosinophil activity in these disorders.
