Reagents include:Coated and uncoated microplatesBlocking buffersDiluents and wash buffersSubstratesPrimary and secondary antibodies Matched antibody pairsUse our broad primary antibody portfolio to design your own ELISA. An important consideration in designing a sandwich ELISA is that the capture and detection antibodies must recognize two different nonoverlapping epitopes. When the antigen binds to the capture antibody, the epitope recognized by the detection antibody must not be obscured or altered. Capture and detection antibodies that do not interfere with one another and can bind simultaneously are called matched pairs and are suitable for developing a sandwich ELISA.Use our Antigen Search tool to find antibodies to compatible binding regions. With our unique search experience, you can quickly identify the most suitable antibodies from our broad catalog.Search for antibodies or find out more at thermofisher.com/antibodiesFind your optimal set of ELISA reagents using the ELISA BuilderELISA Builder makes it easy to find the best solution for developing your own ELISA assay.
