          PSD-95 Antibody (51-6900) in ICC/IF

          Immunofluorescent analysis of PSD-95 (green) and MAP2 (red) on rat primary cortical neurons cultured for 28 days in the B-27 Plus Neuronal Culture System (Product # A3653401). At day 28 the cells were fixed with 4% paraformaldehyde for 15 min, permeabilized with 0.1% triton X-100 for 30min, and blocked with 1% BSA for 30 min at room temperature. Cells were stained with anti-PSD95 antibody (Product # 51-6900) at a dilution of 1:200, and anti-MAP2 (Product # 13-1500) at a dilution of 1:400, in 1% BSA staining buffer, overnight at 4C, and the...

          Product Specific Information

          This antibody recognizes the 95 kDa PSD-95 protein. Cross-reactivity with an unknown protein at ~50 kDa has been observed in western blots with rat brain homogenates. Western blots with mouse brain homogenates did not show such a band.

          Positive reactivity of this antibody was confirmed on western blots of rat brain homogenates and lysates of PSD-95- transfected HEK293 (human embryonic kidney) cells.

          Target Information

          Post Synaptic Density 95 kDa (PSD-95), also known as synapse associated protein 90 kDa (SAP90), is one of a family of membrane-associated proteins found in the postsynaptic density in forebrain neurons and certain presynaptic structures in the cerebellum. Like other members of the family, PSD-95 has three 90 amino acid repeats called PDZ domains followed by an SH3 domain and a yeast guanylate kinase homology (GuK) domain. PSD-95 is believed to participate in the clustering of certain proteins, including NMDA receptors, Shaker-type potassium channels at the synaptic membrane in central nervous system (CNS) neurons. There are two principal modes of interaction between PSD-95 and other proteins. NMDA receptors and shaker-type potassium channels both share C-terminal sequence homology consisting of a threonine/serine-X-valine-COOH (T/SXV) motif. Other neuronal proteins that share this motif (beta 1 adrenergic receptor, some serotonin receptors, some sodium channel subunits, and additional potassium channel subunits), and some of these proteins may interact with PSD-95 by binding to its PDZ domains. Neuronal nitric oxide synthase (nNOS), which lacks the T/SXV motif but which has its own PDZ domain, has been shown to associate with PSD-95 in vitro through a pseudo-homotypic PDZ-PDZ interaction.
