Anti-Glutamic Acid Decarboxylase-67 Antibody
Glutamic Acid Decarboxylase-67 (GAD 67)
Human Glutamic Acid Decarboxylase (GAD-67), [EC 184.108.40.206] 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 12 months (provided they remain sterile). Do not freeze these antibodies unless you want to store them for longer periods of time. Note, however, that each time an antibody preparation is frozen, about half of its binding activity is lost.
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.
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.
