There are two forms of the enzyme glutamic-acid decarboxylase (GAD), a 65-kDa form (GAD65) and a 67-kDa form (GAD67) which are the result of the expression of different genes. Further splicing of GAD 67 produces one or two smaller variants, including GAD25 and GAD44. GAD67 and GAD65 are expressed in adult brain and the pancreas. The truncated forms GAD25 and GAD44 are expressed during embryonic development. Glutamic acid decarboxylase enzyme functions to catalyze the production of gamma-aminobutyric acid from L-glutamic acid.

Cross-reacts with GAD25, GAD44 and GAD65/GAD2
Each new lot of this antibody is tested to confirm that it recognizes a single immunoreactive band of expected molecular weight when used to probe brain lysate.
These antibodies are to be used as research laboratory reagents and are not for use as diagnostic or therapeutic reagents in humans.
