Mouse anti Huntingtin antibody, clone HDC8A4 reacts with an epitope corresponding to the HDC region (2703 - 2911 amino acids) of the huntingtin protein.

Mouse anti Huntingtin antibody, clone HDC8A4 detects a ~350 kDa band on western blots but also detects smaller degradation products of huntingtin. Clone HDC8A4 recognizes both denatured and native huntingtin in human brain.

The combined use of Mouse anti Huntingtin antibody, clone HDC8A4 (MCA2051) and HDB4E10 (MCA2050) demonstrate that huntingtin is enriched in neuronal cells in the brain.
