Anti-PCP4 Antibody

PCP4 (Purkinje Cell Protein 4), also known as PEP-19, is a small calmodulin-binding protein enriched in cerebellar Purkinje cells and certain neuronal populations, where it modulates calcium- and calmodulin-dependent signaling and is widely used as a marker in neuroanatomical studies. This rabbit polyclonal antibody from Antibodies.com is raised against PCP4 and supplied as an unconjugated reagent in a 100 µL vial, validated for Western blot (WB) and immunohistochemistry (IHC) workflows. Reactivity has been confirmed against human and mouse samples, supporting cross-species studies of cerebellar development, motor learning paradigms, and altered PCP4 expression in neural tissue. For optimal stability, aliquot on arrival, store at -20 °C, and protect from repeated freeze-thaw cycles. Recommended for research use only, the reagent provides a specific detection tool for laboratories investigating Purkinje cell biology, neurodegenerative disease models, and the broader role of calmodulin-binding proteins in neuronal signaling.
