ELISA and matched antibody pair kits

​Reliable and optimized matched antibody pairs anchor our ELISA kits. Our matched antibody pairs are recombinant, monoclonal antibodies that are developed and optimized for use in relevant sample types like plasma and serum for reliable performance where you need it. Matched antibody pairs are used in our SimpleStep ELISA kits for results that can be confidently reproduced over the course of the study, between researchers and across different ELISA-based assays.
