Rabbit IL-4 PharmaGenie ELISA Kit (SBRS1256)

The Assay Genie Rabbit IL-4 PharmaGenie ELISA Kit enables quantitative measurement of interleukin-4 (IL-4) in rabbit biological samples. IL-4 is a pleiotropic cytokine central to Th2 lymphocyte differentiation, B-cell class switching to IgE, and the orchestration of allergic and anti-parasitic immune responses, making this kit valuable for immunological research, vaccine development studies, and allergy model investigations.

This two-antibody capture immunoassay uses pre-coated microplate wells and a standard curve to deliver reproducible results across cell culture supernatants, plasma, and serum samples. Researchers typically use 100 µL of sample per well, with an assay detection range of 15.6 to 1000 pg/mL and a sensitivity below 10 pg/mL.

Reagents are shipped refrigerated and should be stored at 2-8°C until first use, after which standards and detection antibody should be aliquoted and frozen to limit freeze-thaw cycles and preserve activity across the full shelf life of the kit.
