Technical Data
Glutamate Decarboxylase 65 (GAD65)
Gamma-Aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the brain. Glutamic acid decarboxylase (GAD; E.C. catalyzes the decarboxylation of glutamate to produce GABA-the rate limiting step in the synthesis of GABA. The two major isoform of GAD, GAD67 (MW 67kD) and GAD65 (MW 65kD) are derived from distinct genes and differ in their subcellular distribution. GAD67 is 594 aa single chain polypeptide encoded by human chromosome 2 gene, whereas GAD65 is am amphiphilic and membrane anchored protein (585 aa, chromosome 10). GAD isoform shares ~65% homology. GAD is also a major autoantigen associated with SMS (stiff-man syndrome).

Suitable for use in ELISA, Immunoprecipitation and Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000- 1:5000. ~65kD band in rat brain.
ELISA: 1:10,000-1:100,000 using 50-100ng UCP2 control peptide/well.
