Overview
Guinea Pig Anti-PSD-95 Antibody is an antibody targeting Postsynaptic density protein 95, Discs large homolog 4, DLG4, Synapse-associated protein 90, SAP-90, Tax interaction protein 15, MRD62 Polyclonal raised in Guinea Pig (Unconjugated). This antibody is commonly used in WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Postsynaptic density protein 95, Discs large homolog 4, DLG4, Synapse-associated protein 90, SAP-90, Tax interaction protein 15, MRD62 (also reported as Postsynaptic density protein 95, Discs large homolog 4, DLG4, Synapse-associated protein 90, SAP-90, Tax interaction protein 15, MRD62).
- Immunogen/epitope region: Intracellular, between the SH3 and the GK-like domains..
- Homology note: Rat, mouse - identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
- Conjugate/format: Unconjugated (may affect detection channel and background).
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
The postsynaptic density (PSD) is a membrane-associated protein specialized in postsynaptic signal transduction and processing. There are four PSD family members classified according to their molecular weight, including, PSD-95, PSD-93, synaptic associated proteins 97 kDa and 102 kDa. PSD-95 interacts with both ionotropic and metabotropic glutamate receptors via protein-protein interactions and plays a role in their precise assembly and spatial organization as well as coupling of these receptors to downstream signaling events1.PSD-95 contains a SH3 domain, a GK domain and three PDZ domains.
Research relevance and current trends
- Mapping receptor/channel localization across neuronal subtypes and subcellular compartments.
- Linking trafficking or surface expression changes to activity-dependent signaling and plasticity.
- Using KO/KD or blocking-peptide concepts to strengthen antibody-based target assignment.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-PZ009.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
