Product Overview
This rabbit polyclonal antibody detects huntingtin-associated protein 1 (gene HAP1) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 75.5 kDa, and the supplier reports an observed band at about 80 kDa.
Huntingtin-associated protein 1 (HAP1) is a neuronal protein that binds huntingtin, and this interaction is strengthened by the expanded polyglutamine tract found in Huntington disease. HAP1 links cargo to microtubule motor proteins and supports vesicle and receptor trafficking in neurons. It is studied in intracellular transport, neurodevelopment and Huntington disease.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places huntingtin-associated protein 1 in the cytoplasm, cell projection, presynapse and lysosome. Tissue expression noted by UniProt (human): Predominantly expressed in brain. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
