Rabbit IL-21 DIY ELISA Kit

Built for researchers measuring endogenous Interleukin-21 in rabbit specimens, this Assay Genie kit pairs matched capture and detection antibodies with precoated microplate strips, lyophilized standards, and the substrate, wash, and stop reagents needed to generate a full standard curve. The assay is read at 450 nm with background correction at 570 nm and reports a detection range of 15.6 to 1000 pg/mL, with sensitivity around 5 pg/mL. Each well uses a 100 uL sample volume, allowing serum, plasma, or cell culture supernatant to be titrated against a recombinant rabbit IL-21 standard. The DIY configuration supplies reagents for up to 10 plates, letting labs scale longitudinal or cohort studies without reordering consumables. Reconstituted standards and diluted samples are loaded directly after the provided assay buffer, and the colorimetric endpoint is captured on any standard plate reader. Researchers studying B-cell maturation, T-follicular helper activity, or mucosal immunity in rabbit models will appreciate the species-matched reagents and the broad dynamic range that supports both low-level and inflammatory-state IL-21 measurements.
