Custom secondary detection probes for ELISA, Western blot, immunofluorescence, immunohistochemistry, flow cytometry, and related antibody-based workflows. Support includes fluorescent secondary detection probes, enzyme-labeled secondary detection probes, biotin- and streptavidin-based systems, and related detection formats designed to improve signal intensity, assay sensitivity, and workflow flexibility.
Secondary detection probes are used to bind primary antibodies and generate measurable signal in a wide range of immunoassays and imaging workflows. Compared with direct detection approaches, secondary detection systems often provide stronger signal, broader assay flexibility, and improved sensitivity because one labeled secondary probe can support multiple compatible primary antibodies.
Bio-Synthesis provides custom secondary detection probe solutions including fluorescent secondary detection probes, enzyme-labeled secondary detection probes, biotin and streptavidin-based systems, and additional detection formats selected based on host species, assay type, required sensitivity, and downstream detection platform.
