Natalizumab (Tysabri®)Free drug ELISA Kit

Assay Genie’s free-drug ELISA kit is designed for quantitative analysis of natalizumab (Tysabri®) in serum and plasma. It uses a solid-phase, colorimetric sandwich ELISA with an HRP-conjugated probe and TMB chromogen substrate. The resulting colour is proportional to the amount of natalizumab in the sample or standard, and results can be determined directly using the standard curve.

The stated required volume is 10 µL, with a total time of 70 Minutes. The detection limit is 30 ng/mL, spike recovery is 85-115%, and the stated shelf life is 1 year.
