Confocal immunofluorescent analysis of mouse kidney (left) and rat retina (right) using Gephyrin (D4J4R) Rabbit mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).Learn more about how we get our images.
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.

Gephyrin (D4J4R) Rabbit mAb recognizes endogenous levels of total Gephyrin protein.
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser268 of human Gephyrin protein.
The neurotransmitters GABA and glycine activate ligand-gated chloride channels and thus mediate fast synaptic inhibition. Gephyrin is a postsynaptic, scaffolding protein anchoring type A GABA and glycine receptors to the cytoskeleton. In addition to gephyrin’s function clustering synaptic neurotransmitter receptors, it plays an essential role in the biosynthesis of the molybdenum cofactor (MoCo). Molybdenum cofactor chelates and activates sulfite oxidase, an enzyme crucial for survival (1). GSK-3β and Erk1/2 phosphorylate gephyrin at residue Ser270 and Ser268, respectively. These post-translational modifications alter the clustering of gephyrin, effecting the amplitude and frequency of GABAergic inhibitory currents (2,3). Researchers are analyzing the role of abnormal gephyrin clustering and function in major neurological, neuro-developmental and psychiatric disorders (1).
