Confocal immunofluorescent analysis of rat cerebellum at low (left) and high magnification (right) using GAD1 (A9A5X) Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
Confocal immunofluorescent analysis of rat retina (left) and pancreas (right) using GAD1 (A9A5X) Rabbit mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
Recommended Fluorochrome-conjugated Anti-Rabbit secondary antibodies:
NOTE: When using any primary or fluorochrome-conjugated secondary antibody for the first time, titrate the antibody to determine which dilution allows for the strongest specific signal with the least background for your sample.
Cover sections with 4% formaldehyde dilute in 1X PBS.
NOTE: Formaldehyde is toxic, use only in fume hood.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

GAD1 (A9A5X) Rabbit mAb recognizes endogenous levels of total GAD1 protein. This antibody cross-reacts with serum albumin.Species Reactivity:
RatSpecies predicted to react based on 100% sequence homology:
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala15 of human GAD1 protein.
The enzyme glutamate decarboxylase (GAD) is responsible for the synthesis of the essential neurotransmitter gamma-aminobutyric acid (GABA) from L-glutamic acid (1). GAD1 (GAD67) and GAD2 (GAD65) are expressed in nervous and endocrine systems (2) and are thought to be involved in synaptic transmission (3) and insulin secretion (4), respectively. Autoantibodies against GAD2 may serve as markers for type I diabetes (5). Many individuals suffering from an adult onset disorder known as Stiff Person Syndrome (SPS) also express autoantibodies to GAD2 (6).
GAD1 and GAD2 are encoded by separate genes and are coexpressed in most of the GABA-containing neurons (1, 7).
