Affinity purified goat-derived antibody to peridinin chlorophyll protein complex (PerCP). Antibody is highly specific to PerCP with minimal (less than 2%) cross-reactivity observed. Detects tandem dyes such as PerCP-Cy5.5. As a polyclonal antibody, it binds to multiple epitopes on PerCP making it superior to monoclonals. It is designed for the detection of PerCP in immunohistochemistry (IHC) applications.
