ELISA refers to the qualitative and quantitative detection method of combining an antigen or antibody to a solid-phase carrier and using an antigen antibody combined with specificity. ELISA includes sandwich method, indirect method, competition method, etc. Among them, the sandwich ELISA method is of great interest to researchers. Sandwich ELISA method requires antibodies to have high affinity, specificity and sensitivity for antigens.

Antibody pairs refers to two different antibodies generated against the same target, but with different binding regions or epitopes, including capture antibody and detection antibody. Differential epitope recognition allows for simultaneous binding of both antibodies to the same target, making Sandwich ELISAs possible. Antibody pairs are powerful tools used to quantify target analyte from complex samples across a myriad of fields, which are applied in ELISA, Western Blotting, Lateral Flow, TIA, and protein-protein interaction. The choice of antibody pairs varies between the platforms. For Lateral Flow, antibodies pairs must show high specificity for a particular epitope on the target and low cross-reactivity. 

Biotyscience offers thousands of antibody pairs, including human testing materials, animal testing materials and other molecular testing materials. Our products all provide quality inspection reports, for your later experiment escort.
