PSD 95 is a component of postsynaptic densities in central synapses
Guinea pig monoclonal recombinant IgG
Cat. No.: 124 308
Amount: 50 µg
Price: $420.00
Cat. No. 124 308 50 µg purified recombinant IgG, lyophilized. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use.
Antibodies should be stored at +4°C when still lyophilized. Do not freeze!

Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Immunohistochemistry on glyoxal fixed (IHC-G) tissue. The tissue is perfused with saline and afterwards immersion fixed with a glyoxal solution. For details of the glyoxal solution, please refer to the remarks section. Immunoreactivity is usually revealed by fluorescence.

Clone Gp108E10
Subtype IgG2 (κ light chain)
Immunogen Recombinant protein corresponding to PDZ-domain of mouse PSD95 (UniProt Id: Q62108)
Reactivity Reacts with: rat (P31016), mouse (Q62108), chicken, human (P78352).
Other species not tested yet.
Specificity K.O. validated
Matching control protein/peptide 124-01P
Remarks

This antibody is a chimeric antibody based on the well known monoclonal mouse antibody clone 108E10. The constant regions of the heavy and light chains have been replaced by Guinea pig specific sequences. Therefore, the antibody can be used with standard anti-Guinea pig secondary reagents. The antibody has been expressed in mammalian cells.
IHC-G: Fixation with 9% glyoxal, 8% acetic acid, in ddH2O, pH 4.2-4.4, according to Konno et al. 2023 is recommended.

Background

PSD 95 (postsynaptic density protein 95 kDa, also called SAP 90: synapse associated protein of 90 kDa and DLG 4) is a component of postsynaptic densities in central synapses. It contains three PDZ domains. The first and second PDZ domain localizes NMDA receptors and K+ channels to synapses, the third binds to neuroligins which are neuronal cell adhesion molecules that interact with β-neurexins and form intercellular junctions. Thus different PDZ domains of PSD 95 might be specialized for distinct functions.
