conjugate purification, per manufacturer’s protocol (Sulfo-Tag® labeling kit, MSD, Cat. No. R91CN-1). MAbs are designated by the corresponding hybridoma clone numbers, prefixed by designation of the conjugate, for example b-1795 for biotinylated mAb (b-mAb) 1795 and Ru-1443 for Ru(bpy) 3-conjugated mAb 1443. 2.6. ELISA Conditions Ultimately, all biopharmaceuticals are immunogenic and may induce anti-drug antibodies (ADA). This can impact patient safety and drug efficacy, and therefore specific and sensitive ADA detection is a key element of drug development programs, and a regulatory requirement. Oct 12, 2017 · The capture and detection reagents for the ADA assays were generated by conjugating the monoclonal antibody therapeutics to biotin (Sulfo-NHS-LC-Biotin, Thermo Scientific, MA, USA) or ruthenium (Sulfo-TAG-NHS ester, MSD, MD, USA) according to the manufacturers’ instructions.

BioAgilytix leverages the Meso Scale Discovery Electrochemiluminescence (MSD-ECL) platform and its plate-based electrochemical luminescence technology to provide reliable, high quality data for a diverse variety of biological assay used for the development of biologics and cell and gene therapies.

Dec 13, 2017 · The ruthenium within the MSD SULFO TAG drives a redox reaction with the tripropylamine in the MSD Read Buffer T with surfactant and emits light that is detected by the cooled CCD camera within the ...

After washing the plates, goat anti-human IgG SULFO-TAG antibody (Meso Scale Discovery, Gaithersburg, MD) in dilution buffer (0.375–1.25 μg/ml) was added (50 μL/well) to the plates. Plates were gently shaken at room temperature for one hour. ruthenium cation in conjunction with carbon electrode arrays held within microtiter plate footprints. A capture antibody is first non-specifically adsorbed onto the carbon surface of the plate and after analyte capture, a detection antibody labeled with the MSD SULFO-TAG ruthenium-based reagent (the electrochemilumi-

MSD TAG-NHS-Ester, or Ruthenium (II) tris-bipyridine, N-hydroxysuccinimide is an amine-reactive label often used for detection in assays formatted with MSD technol- Meso Scale Discovery The antibodies used in MSD detection are modified to have a Sulfo-tag ™ label which catalyze a chemical reaction only activated while reading a plate. This technology is most attractive to clinical settings because it is fast and noninvasive biochemical assay.

MSD Sulfo-Tag was determined by measuring the absorbance at 455 nm of the labeled protein conjugate and dividing the result by the extinction coefficient of the label (15,400 M1 cm ). To calculate the MSD Sulfo-Tag label/protein ratio, the concentration of MSD Sulfo-Tag was divided by the protein concen-tration determined by the BCA assay.
