General description

Abnormal stretch of triplet CAG (or CAA) codon produces a homomeric repeat of glutamine residues beyond the critical threshold and will lead to neurodegenerative disease. Monoclonal mouse anti-polyglutamine antibody can be used to detect poly Q protein expression and in western blot. Monoclonal anti-polyglutamines antibody reacts specifically to homomeric polyglutamines independent of the species.

Immunogen

GST-human Huntingtin (N-terminal fragment of 171 amino acids containing 65Q).

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)
Monoclonal anti-polyglutamines antibody may be used for ELISA, immunoblot and slot blot. It can also be used in immunoprecipitation and immunocytochemistry.

Physical form

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