一般說明
Gutamic acid decarboxylase (GAD; E.C. 4.1.1.15) is the enzyme responsible for the conversion of glutamic acid to gamma-aminobutyric acid (GABA), the major inhibitory transmitter in higher brain regions, and putative paracrine hormone in pancreatic islets. Two molecular forms of GAD (65kDa and 67kDa, 64% aa identity between forms) are highly conserved and both forms are expressed in the CNS, pancreatic islet cells, testis, oviduct and ovary. The isoforms are regionally distributed cytoplasmically in the brains of rats and mice (Sheikh, S. et al. 1999). GAD65 is an ampiphilic, membrane-anchored protein (585aa), encoded on human chromosome 10, and is responsible for vesicular GABA production. GAD67 is cytoplasmic (594aa.), encoded on chromosome 2, and seems to be responsible for significant cytoplasmic GABA production. GAD expression changes during neural development in rat spinal cord. GAD65 is expressed transiently in commissural axons around E13 but is down regulated the next day while GAD67 expression increases mostly in the somata of those neurons (Phelps, P. et al. 1999). In mature rat pancreas, GAD65 and GAD67 appear to be differentially localized, GAD65 primarily in insulin-containing beta cells and GAD67 in glucagon-containing (A) cells (Li, L. et al. 1995). GAD67 expression seems to be particularly plastic and can change in response to experimental manipulation (for example neuronal stimulation or transection) or disease progression and emergent disorders like schizophrenia (Volk et al., 2000). Colocalization of the two GAD isoforms also shows changes in GAD65/GAD67 distributions correlated with certain disease states such as IDDM and SMS.
特異性
Recognizes the lower molecular weight isoform of the two GAD isoforms identified in brain (Gottlieb, et al., 1986; Chang & Gottlieb, 1988). This monclonal antibody can be used for immunohistochemical localization in brain or pancreas. Anti-GAD has also been used to label purified GAD on Western blots (Chang & Gottlieb, 1988).
免疫原
Purified rat brain GAD.
應用
Anti-Glutamate Decarboxylase Antibody, 65 kDa isoform, clone GAD-6 is an antibody against Glutamate Decarboxylase for use in IH & WB.
Immunohistochemistry: (≤ 1 μg/ml) Optimal working dilutions must be determined by end user.
Immunohystochemical Staining Procedures
The following procedure was developed to localize GAD in rat brain sections of cerebellum. Perform all steps at room temperature unless otherwise indicated. Where normal serum is indicated, use normal serum from the same species as the source of the secondary antibody.This procedure represents suggested guidelines for the use of anti-GAD. Fixation regimen, antibody concentrations, and incubation conditions for a given experimental system should be determined empirically.
1. Perfuse rats with 100 mM phosphate buffer, pH 7.4, containing 1% paraformaldehyde, 0.34% L-lysine, and 0.05% sodium m-periodate (1% PLP).
2. Postfix brains in 1% PLP for 1-2 hours. Longer fixation times may reduce labeling intensity.
3. Transfer brains to 100 mM phosphate buffer containing 30% sucrose, and gently agitate on a shaker platform at +4°C for 48-60 hours.
4. Using a sliding microtome, cut 30 mm sections of frozen cerebellum. As the sections are cut, collect them in a vial of cold 100 mM phosphate buffer.
5. Incubate sections in phosphate-buffered saline (PBS) containing 1.5% normal serum and 0.2% TritonX-100 for 30 minutes.
6. On a shaker platform, incubate sections with anti-GAD (diluted in PBS containing 1.5% normal serum and 0.2% Triton X-100 to a final antibody concentration of 1 mg/ml) for 12-36 hours at +4°C.
7. On a shaker platform, rinse sections eight times, 10-15 minutes per rinse, in PBS.
8. Detect with a standard secondary antibody detection system (Hsu et al., 1981; Falini & Taylor, 1983; Harlow & Lane, 1988; Taylor, 1978).
9. Mount sections, dehydrate, and apply coverslips.
