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