Matched antibody pair kits and reagents deliver consistent, specific, and sensitive results.
Batch-to-batch consistency: only recombinant monoclonal antibodies are used in our matched antibody pairs.
Specificity: antibody pairs are screened in plasma and serum to ensure specificity in complex samples.
Sensitivity: benchmarked against commercially available antibody pairs to ensure equivalent or superior performance compared with the competition.
Matched antibody pair kits include a titrated capture and biotinylated detector antibody pair and a calibrated protein standard. Kits are available in two sizes, with enough reagents for either 2 or 10 x 96-well plates using a standard sandwich ELISA.
Figure 1. The human IL-1Ra matched antibody pair kit (ab210888) is 10-fold more sensitive than a rabbit polyclonal antibody pair when measuring human IL-1Ra standard protein using a sandwich ELISA.
