MSD Assays – Rapid & Sensitive

With the MESO QuickPlex SQ 120 instrument, PBL can develop and validate single or multiplex MSD-ECLA assays for a range of analytes in complex sample matrices such as serum, plasma, urine, sputum and cell culture mixtures. The MSD platform can help develop assays with minute sample amounts and low variability between multiple sample runs.  MSD assays can be used for a variety of applications – from immunogenicity to pharmacokinetics (PK), pharmacodynamics (PD), biomarker analysis and even lot release testing. We are able to conduct assays on samples from rodents, non-human primates and humans under non-GLP, GLP and GMP conditions.

Technology behind MSD

The rapid read-times and sensitivity of MSD assays are powered by a combination of electrochemiluminescence (ECL) and MSD’s proprietary MULTI-ARRAY and MULTI-SPOT technology. Electrochemiluminescence assays (ECLA) use labels called SULFO-TAGs. When electricity is applied to high voltage carbon electrodes located at the bottom of MULTI-ARRAY and MULTI-SPOT plates, the SULFO-TAGs are stimulated and emit light.

MSD Services

The bioanalytical team at PBL has extensive experience in method development and validation for both preclinical and clinical trials using several techniques including ELISA. We bring the same expertise to MSD’s ECL assays. With MSD’s QuickPlex, the PBL team can help clients develop ECLA assays with increased dynamic range and sensitivity while using less sample amount and reagents. We can also develop multiplex assays on this instrument. Based on your project needs, we can choose from a wide variety of commercially available assay kits (V-PLEX, U-PLEX, R-PLEX), components and reagents to develop the most suitable assay for you.
