Description: Many biotin molecules can be conjugated to a secondary antibody with the additional advantage of streptavidin having a high affinity for biotin. Through this amplification step and having the streptavidin bound to labels such as HRP or fluorescent probes, proteins which are expressed at low levels are more likely to be detected. For most assays, the biotin-labeled secondary antibody is added first, sequentially followed by the streptavidin conjugated to a label e.g. HRP.
