Human IL-4 ELISA Kit

From Antibodies.com, this sandwich ELISA kit is designed for the quantitative determination of human IL-4 in serum. The colorimetric assay runs in 4 hours and reaches a sensitivity of less than 0.48 pg/ml, with a working standard range of 7.81 to 500 pg/ml. IL-4 in standards and samples is captured on a pre-coated microplate, detected with a biotinylated antibody, and visualised using an HRP-streptavidin conjugate and TMB substrate, with absorbance measured at 450 nm. The kit is specific for IL-4, with no reported cross-reactivity with other analogs or variants, and is supplied with an easy-to-follow protocol.
