Application Note

Quantification of ADAMTS13 Activity by FRET Assay and Kinetic Data Analysis Using MyAssays Desktop on the VICTOR Nivo


In this application note, the VICTOR® Nivo multimode plate reader is used in combination with MyAssays® Desktop Software to perform kinetic assays and analyze data in a straightforward and efficient manner.

ADAMTS13 is a biomarker of thrombotic thrombocytopenic purpura (TTP), a rare disease that can be controlled by plasma exchange which is supposed to supply ADAMTS13 to patients and/or to remove neutralizing autoantibodies against ADAMTS13.

VICTOR Nivo was used to measure the activity of the enzyme ADAMTS13 in plasma samples, using the commercial substrate “FRETS-VWF73”. As variant of the original protocol, PerkinElmer half-area plates were used to save reagent and sample (assay volumes reduced by half as compared to the original protocol).
