Microplates Coating
Microplate coating involves the precise modification of the inert polystyrene surfaces within microplate wells to enable the stable and efficient immobilization of critical biological molecules. This foundational process is essential for a myriad of assays, including immunoassays and nucleic acid hybridization. While traditional methods often rely on passive adsorption, leading to limitations such as low binding capacity and non-specific interactions, advanced coating techniques employed significantly enhance surface functionality. These innovations ensure superior ligand immobilization, ultimately boosting assay sensitivity, specificity, and overall reproducibility.
