Immunoassay Service

An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes). The molecule detected by the immunoassay is often referred to as an "analyte" and is in many cases a protein, although it may be other kinds of molecules, of different sizes and types, as long as the proper antibodies that have the required properties for the assay are developed. Analytes in biological liquids such as serum or urine are frequently measured using immunoassays for medical and research purposes. CD BioSciences provides professional immunoassay service services to meet the specific needs of different customers. If you have any needs in this regard, please feel free to contact us.


Immunoassays rely on the ability of antibodies to recognize and bind specific macromolecules in a possibly complex mixture of macromolecules. In immunology, the specific macromolecule that binds to the antibody is called the antigen, and the area on the antigen that binds to the antibody is called the epitope. In some cases, immunoassays may use an antigen to detect the presence of antibodies that recognize the antigen in the solution. In other words, in some immunoassays, the analyte may be an antibody rather than an antigen. In addition to the binding of antibodies to their antigens, another key feature of all immunoassays is the means of generating a measurable signal in response to binding.
