>Meso Scale Discovery Electrochemiluminescence (MSD) Service
Meso Scale Discovery Electrochemiluminescence (MSD) uses sandwich ELISA method coupled with electrochemiluminescence (ECL) detection and plate array technology to provide highly sensitive and multiplexed detection of analytes in a complex biological matrix. MSD can be used for analyzing biomarkers especially most kinds of cytokines and chemokines, perform PK/PD analysis, and carry out ADA immunogenicity testing in a broad range of sample types such as blood, serum, and tissue, etc.
MSD uses Sandwich ELISA method coupled with Electrochemiluminescence detection for multiplexed detection
QuickPlex SQ 120
Utilizing the MSD QuickPlex SQ120 allows ACROBiosystems to perform MSD’s proprietary assays containing multi-array technology. This provides significantly increased sensitivity and dynamic range over standard ELISA with the added benefit of multiplexing. Fast, yet continuous, non-destructive reads produce consistent assay data with low sample volume requirements and minimal reagent consumption.

Fig.3 Anti-Ritux*mab antibodies bridging MSD for anti-drug antibody (ADA) assay development. Added the mix solution (biotinylated Ritux*mab at 5 µg/mL, SULFO-Ritux*mab at 5 µg/mL and increasing concentrations of Ant-Ritux*mabAntibodies (Cat.NO.RIB-Y36, 100% human serum). Detection wasperformed using MSD Assay with a sensitivity of 0.97 ng/mL.
