Overview
Anti-PSD-93 Antibody is an antibody targeting Discs large homolog 2, Dlg2, Chapsyn-110 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IHC, IP, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Discs large homolog 2, Dlg2, Chapsyn-110 (also reported as Discs large homolog 2, Dlg2, Chapsyn-110).
- Immunogen/epitope region: Between PDZ2 and PDZ3 domains..
- Homology note: Human - 42/44 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- KO-validated: yes (validation context may be assay-dependent).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by DNA sequence and SDS-PAGE.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Chapsyn 110 (also known as PSD-93 and DLG2) is a PDZ containing domain protein that is also a member of the membrane-associated guanylate kinase (MAGUK) family of multi-domain adaptor proteins1,2.PDZ domains are conserved protein domains of about 90 amino acids involved in protein-protein recognition, protein targeting and assembly of multi-protein complexes. The name PDZ derives from the first three proteins in which these domains were identified: PSD-95 (a 95 kDa protein involved in signaling at the post-synaptic density), DLG (the Drosophila melanogaster Discs Large protein) and ZO-1 (the zonula occludens 1 protein involved in maintenance of epithelial polarity)1,2.MAGUKs are scaffolding proteins that comprise several modular protein binding motifs including one or more PDZ domains, a Src homology 3 (SH3) domain, and a catalytically inactive guanylate kinase-like domain1,2.The multidomain nature of PDZ-containing proteins enables them to interact with multiple binding partners and hence organize larger signaling protein complexes.Indeed, Chapsyn 110 has been shown to participate in the postsynaptic density, a dedicated structure formed in postsynaptic nerve terminals that includes a specialized assembly of ion channels, receptors and signaling molecules that are involved in information processing and the modulation of synaptic plasticity1,2.
Research relevance and current trends
- Comparing target expression across perturbations, genotypes, or treatment conditions.
- Interpreting localization shifts alongside pathway or phenotypic readouts.
- Using orthogonal controls (KO/KD, peptide competition, isotype concepts) to support conclusions.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Immunoprecipitation (IP): enrich the target for downstream detection or complex analysis (context-dependent).
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.
- Conceptual control: KO/KD samples provide orthogonal support for target assignment when available.
- Provided control suggestions: Negative control: BLP-PZ002.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
