What Does DAS Stand For?
DAS stands for Double Antibody Sandwich
DAS, or Double Antibody Sandwich, is an immunoassay technique commonly used in laboratory diagnostics and research to detect specific antigens in a sample. This method involves the use of two distinct antibodies that capture the target antigen between them, enhancing specificity and sensitivity. The first antibody is immobilized on a solid surface and binds to the antigen, while the second antibody, tagged with a detectable marker, binds to another site on the antigen. This sandwich formation allows for effective quantification and analysis of the antigen, making DAS a valuable tool in various biomedical applications.
