Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.

PostSynaptic Density (PSD) refers to a dense region of submembranous cytoskeleton found most prominently in postsynaptic membranes of the CNS.  Possible functions for the PSD include regulation and aggregation of receptors,  structural stabilization of the synaptic junction, and transduction of signals from membrane receptors.  Some of the proteins associated with the PSD are fodrin, tubulin, calmodulin, CaM Kinase II, PSD-95, and PSD-93.  PSD-95 (SAP90) is a protein that interacts with the NMDA receptor NMDAR2B, neuronal NOS  (nNOS or bNOS), and other proteins.  PSD-95 contains one SH3 domain in its carboxy-terminal domain, as well as three conserved repeat regions called GLGF or PDZ domains.  nNOS, which is concentrated in synaptic junctions, also contains a PZD domain.  PSD-95 and nNOS interact via their respective PZD domains, which may mediate the binding of nNOS to skeletal muscle syntrophin.

This antibody is routinely tested by western blot analysis.  Other applications were tested in BD Biosciences Pharmingen during antibody development only or reported in the literature.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
