Primary antibodies specifically bind to the protein or biomolecule of interest and are directly conjugated to a dye or an enzyme for detection or detected with a secondary antibody. Directly conjugated primary antibodies simplify assays by eliminating additional steps and reducing potential species cross-reactivities and non-specific binding.
Our in-house validated conjugated primary antibodies allow for greater flexibility in multicolor experiments such as flow cytometry and immunofluorescence. We offer bright conjugates for low abundance analytes and more subdued dyes for high abundance targets. SouthernBiotech offers an extensive portfolio of directly conjugated monoclonal and polyclonal primary antibodies to over 20 fluorescent and enzyme labels allowing for the customization of your assay.
