Store unopened kits at 2–8°C. Do not freeze pre-coated plates. Once opened, use remaining strips within 1 month when stored in the sealed pouch with desiccant at 2–8°C.

In most cases, yes — but concentrations may differ between matrices. We recommend running a pilot comparison if switching sample types. Check the product datasheet for validated sample types and recommended MRD.

Read at 450 nm with a reference wavelength of 630 nm (for TMB substrate). Read within 15 minutes of adding stop solution. Use a 4-parameter logistic (4PL) curve fit for standard curve calculation.

Sandwich ELISA uses two non-overlapping epitopes for high-sensitivity detection of proteins and cytokines (signal increases with concentration). Competitive ELISA works for small molecules or single-epitope targets (signal decreases with concentration).

All kits are Research Use Only (RUO) unless explicitly labeled otherwise. For IVD-grade requirements or custom assay development, contact our team.

Yes. Every kit ships with a lot-specific CoA including standard curve, sensitivity (LoD/LoQ), linearity, spike-recovery (80–120%), and precision data (intra-assay CV <8%, inter-assay CV <10%). Downloadable on each product page.
