Glutamic Acid Decarboxylase-67 (GAD 67)
Human Glutamic Acid Decarboxylase (GAD-67), [EC 220.127.116.11] is a 66,987 dalton protein (594 amino acids) selectively expressed in a subpopulation of GABAergic neurons of the CNS. It catalyzes the decarboxylation of glutamic acid, forming the inhibitory neurotransmitter beta-amino butyric acid (GABA). It is also know as GAD-1.

Store at 4°C in the dark. Under these conditions, the antibodies should have a shelf life of at least twelve months, provided they remain sterile. For longer term storage, aliquot and freeze to avoid freeze-thaw of the antibody.
Chickens were immunized with a synthetic peptide / keyhole limpet hemocyanin (KLH) conjugate. This synthetic peptide corresponded to a region near the Cterminus of this gene product, and was 100% conserved between the human (Q99259, NCBI), mouse (P48318, NCBI) and rat (NP_058703, NCBI) gene products. After repeated injections into the hens, immune eggs were collected, and the IgY fractions were purified from the yolks. These IgY fractions were then affinity-purified using a peptide column, the concentrations of the eluate adjusted to 100 µg/mL, and the preparation was filter-sterilized through a 0.45 µm filter.
Phosphate-buffered (10 mM) isotonic (0.9%, w/v) saline (“PBS," pH 7.2) with sodium azide (0.02%, w/v) added as a preservative.
This antibody preparation was analyzed by immunohisto-chemistry (at a concentration of 1 µg/mL) using fluorescein-labeled goat anti-chicken IgY (1:500 dilution, Aves Labs Cat.# F-1005) as the secondary reagent.
These antibodies are to be used as research laboratory reagents and are not for use as diagnostic or therapeutic reagents in humans.
