Affinity purified goat-derived antibody to phycoerythrin (PE). Antibody is highly specific to PE with minimal (less than 2%) cross-reactivity observed. Detects tandem dyes such as PE-Cy5 and PE-Cy7. As a polyclonal antibody, it binds to multiple epitopes on PE making it superior to monoclonals. It is designed for the detection of PE in immunohistochemistry (IHC) applications.
