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.

Expansion Microscopy (ExM) is a sample preparation and imaging method which employs a dense interconnected web of swellable polymer within a biological specimen. A significantly higher effective resolution can be achieved with a standard microscope setup. For additional experimental details, please refer to the Remarks section.

Remarks

This antibody is a chimeric construct consisting of the anti-PSD 95 single-domain antibody 1B2 genetically fused to rabbit IgG1 Fc domain. It can be used in combination with standard anti-rabbit secondary reagents binding the IgG Fc-domain.
ICC: We recommend the PSD95 FluoTags N3702 for best results. 
IHC: We recommend the PSD95 FluoTags N3702 for best results. 
ExM: This antibody has been successfully used for the epitope-preserving magnified analysis of the proteome (eMAP) expansion microscopy method (Park et al. 2021. PMID: 34767453).
Variance from the standard protocol:
Clearing after gel-embedding: overnight at 37°C followed by 10 minutes at 88°C.

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.
