Anti-PSD95 (phospho S295) antibody (ab16495)


  • Product nameAnti-PSD95 (phospho S295) antibody
    See all PSD95 primary antibodies
  • Description
    Rabbit polyclonal to PSD95 (phospho S295)
  • SpecificityPSD95 has a predicted band size of 95kDa, however in western blot gels it tends to run at a larger band size (~105kDa), this is thought to be due to post-translational modification (possibly palmitoylation) of PSD95 proteins.
  • Tested applicationsSuitable for: IHC-FoFr, WBmore details
  • Species reactivity
    Reacts with: Mouse, Rat
    Predicted to work with: Human
  • Immunogen

    Synthetic peptide conjugated to KLH derived from within residues 250 - 350 of Mouse PSD95, phosphorylated at S295.

    (Peptide available as ab17222.)

  • Positive control
    • mouse hippocampus



Our Abpromise guarantee covers the use of ab16495 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-FoFr 1/300.
WB Use a concentration of 0.3 - 3 µg/ml. Detects a band of approximately 105 kDa (predicted molecular weight: 95 kDa).


  • FunctionInteracts with the cytoplasmic tail of NMDA receptor subunits and shaker-type potassium channels. Required for synaptic plasticity associated with NMDA receptor signaling. Overexpression or depletion of DLG4 changes the ratio of excitatory to inhibitory synapses in hippocampal neurons. May reduce the amplitude of ASIC3 acid-evoked currents by retaining the channel intracellularly. May regulate the intracellular trafficking of ADR1B.
  • Tissue specificityBrain.
  • Sequence similaritiesBelongs to the MAGUK family.
    Contains 1 guanylate kinase-like domain.
    Contains 3 PDZ (DHR) domains.
    Contains 1 SH3 domain.
  • DomainThe PDZ domain 3 mediates interaction with ADR1B.
    The L27 domain near the N-terminus of isoform 2 is required for HGS/HRS-dependent targeting to postsynaptic density.
  • Post-translational
    Palmitoylation of isoform 1 is required for targeting to postsynaptic density.
  • Cellular localizationCell membrane. Cell junction, synapse, postsynaptic cell membrane, postsynaptic density. Cell projection, axon. Cell junction, synapse. High levels in postsynaptic density of neurons in the forebrain. Also in presynaptic region of inhibitory synapses formed by cerebellar basket cells on axon hillocks of Purkinje cells.

Anti-PSD95 (phospho S295) antibody images

  • Lane 1 - Input lane, 25-50µg mouse forebrain brain lysate probed with ab16495 PSD95 (phospho S295) antibody (1µg/ml)

    Lane 2 - IP lane, ~500µg mouse forebrain brain lysate probed with ab16495 PSD95 (phospho S295) antibody (1µg/ml)

    The IP lane (2) shows an enrichment of PSD95 (phospho S295) at the expected band size (~105kDa).

  • Immunohistochemistical detection of PSD95 (phospho S295) using antibody ab16495 on PFA perfusion-fixed mouse brain sections (30 microns). Primary antibody ab16495 was diluted at 1/300 and incubated for 18 hours @ 20°C in PBS + 0.3 % Triton X100. Secondary antibody: goat anti-rabbit Alexa Fluor 488 (1/1000). The image show immunostaining obtained in the mouse cerebellum using this antibody using direct fluorescence. The antibody stained granular cerebellar cells. Image [A] shows the staining obtained using the antibody, whereas image [B] is the staining captured with the same setup of acquisition for the negative control (lack of primary antibody). The arrows show the location of purkinje cells.
