Antibody Pairing-Custom ELISA Development Service


KMD Bioscience can provide you with project-specific antibody screening and matching services based on GMP guidelines.


Antibody Pairing Service-ELISA Enzyme Kit Development:


ELISA (Enzyme-Linked Immunosorbent Assay) is a medium- and high-throughput screening technology based on solid-phase carriers. It is widely used to qualitatively and quantitatively detect the content of peptides, proteins, antibodies and hormones in samples. In an ELISA assay, the antibody or antigen is pre-bound to the ELISA plate (96-well plate) and labeled with horseradish peroxidase (HRP), alkaline phospholipase (AP) or other chemiluminescent groups. The antibody or antigen is subjected to a color reaction. As shown in Figure 1, there are four main ELISA methods: Sandwich ELISA, Competitive ELISA (detection of antigen), Indirect ELISA (assay antibody) or Competitive ELISA (detection of small molecule compound), and the latter three are more commonly used.

The development of the ELISA (enzyme-linked immunoassay) kit mainly involves the screening of antibody pairs. The performance of the antibody, and the difference in recognition sites directly determine the quality of the ELISA kit. After antibody pairing, the work to be verified includes the detection sensitivity, linear range, repeatability, specificity and thermal stability.
