General description

Huntington disease (HD) is a hereditary, progressive, neurodegenerative ailment characterized by personality changes, motor impairment and subcortical dementia. The molecular basis of the disease involves the expansion of the trinucleotide CAG, coding for polyglutamine in the first exon of a chromosome four gene (4p16.3), which normally produces a widely expressed 3136 a.a. (~350 kDa) protein huntingtin with unclear function. The protein is found in the perinuclear region along with microtubules, and in the centrosomal region along with gamma-tubulin. Huntingtin is necessary for neuronal survival and is involved in synaptic vesicle trafficking, microtubule binding and may also have a role in apoptosis. In the HD condition, neuronal cells with the mutant form of huntingtin possess intranuclear aggregations of the N-terminal fragment, causing damaging inclusions in perinuclear locations and striatal neuron cell death. Wild-type huntington and anti-huntingtin reduce aggregation and cellular toxicity of the mutant huntingtin form in mammalian cell models of HD. Huntingtin is known to interact with GAPDH, HAP-1, SP1 and TAFII130.


Huntingtin Protein. No detectable cross reactivity to other proteins by Western blot.


Epitope: a.a. 181-810
Huntingtin fragment from a.a. 181 to 810 as a fusion protein.


Anti-Huntingtin Protein Antibody, a.a. 181-810, clone 1HU-4C8 is an antibody against Huntingtin Protein for use in ELISA, IC, IH(P), IP & WB.
A 1:500-1:5,000 dilution of a previous lot was used on ELISA.

A 1:500-1:5,000 dilution from a previous lot was used on frozen and microwave oven treated paraffin sections (human tissue).

1:500-1:5,000 on a previous lot was used on transfected cells.

A 1:500-1:5,000 dilution of a previous lot was used on immunoprecipitation.

Western blot:
1:500-1:5,000. Should detect a band migrating at approximately 350-400 kDa by Western blot (Nature Genetics 10:104-110.).

Optimal working dilutions must be determined by the end user.
