Trastuzumab (Herceptin, Herclon) ELISA Kit

Assay Genie’s colorimetric ELISA kit is intended for therapeutic drug monitoring and the quantitative determination of free trastuzumab in serum and plasma. It uses a solid-phase sandwich enzyme immunoassay with a horse radish peroxidase-conjugated probe and tetramethylbenzidine (TMB) substrate; the colour developed is proportional to the amount of trastuzumab in the sample or standard.

The stated detection limit is "2 ng/mL", with recovery of "85-115%" and a required volume of "10 µl". The manufacturer describes the assay as a simple-protocol kit developed for quantitative analysis at high specificity.
