Typically, a minimum of 3-6 amino acids is used to generate an antibody. Peptides that are 10-20 amino acids long are considered ideal for antibody preparation, while those used for structure/function studies can vary in length. In the literature, the N-terminal fragments of Huntingtin in the cortex have been fully characterized. The second protease-susceptible domain, known as the “B” domain, is expected to be located farther from the N-terminal and in proximity to the region corresponding to residues 181–810. This sequence is utilized to validate the specificity of the antibody.

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.

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