Used to measure interleukin-5 (IL-5) levels in biological samples from sheep, this ELISA research kit enables accurate quantification of IL-5 in serum, plasma, and cell culture supernatants. It is widely applied in immunological studies to investigate Th2-type immune responses, particularly in parasitic infections such as helminths, where IL-5 plays a key role in eosinophil activation and regulation. Researchers also use the kit to evaluate vaccine efficacy, study allergic inflammation, and assess immune modulation in veterinary and preclinical research settings. The assay supports high sensitivity and specificity, making it suitable for monitoring cytokine dynamics in experimental models involving sheep.
