Accurate affinity profiling of a SARS-CoV-2 antibody in serum

30 Sept 2021

The ability to accurately characterize the immune response against SARS-CoV-2 is of vital importance in managing the current COVID-19 pandemic. Measuring antibody affinity under physiologically relevant conditions in complex mixtures like serum remains challenging but is critically important to furthering our understanding of the immune response and protection window in patients and vaccinated individuals. Using Microfluidic Diffusional Sizing (MDS), we have characterized an anti-spike S1 antibody by measuring its binding affinity to the receptor binding domain (RBD) of the SARS-CoV-2 spike protein directly in serum.

BiosensorsBiosensors are devices used to detect an analyte using biological molecules specific to the analyte coupled to a detector. Biosensor instruments may be photometric, typically using surface plasma resonance (SPR), electrochemical or QCM (quartz crystal microbalance) biosensors. Biosensors should be selective, portable, robust and sensitive and have a fast response time. Systems may be manual or automated and usually have associated software.AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.CoronavirusCoronaviruses are a large family of viruses that can cause illnesses ranging from the common cold to more severe diseases like COVID-19.
