General description

Anti-Huntingtin (N-terminal) is produced in rabbit using as immunogen a synthetic peptide corresponding to human huntingtin, conjugated to KLH.

Application

Anti-Huntingtin (N-terminal) antibody has been used:
  • in magnetic bead-assisted immunopurification
  • in western blotting
  • in immunofluorescent staining
  • in immunoblotting

Biochem/physiol Actions

Huntingtin (Htt) is essential for embryonic development and neurogenesis. Htt associates with various cell organelles like the nucleus, endoplasmic reticulum and Golgi complex. It is also found in neurites and synapses where it associates with vesicular structures and microtubules, suggesting that it may play a role in intracellular vesicular trafficking, calcium homeostasis, neuronal survival, morphogenesis and transcriptional regulation. Aberrant expansion of glutamine repeats (polyQ) in the N-terminal region of huntingtin (htt) causes Huntington′s disease (HD) which is an autosomal dominant neurodegenerative disorder.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Huntington's disease (HD) is a monogenic disorder caused by an aberrant expansion of CAG repeats in the huntingtin gene (HTT). Pathogenesis is associated with expression of the mutant (mHTT) protein in the CNS, with its levels most likely related to
