Overview
Anti-SAP102 Antibody is an antibody targeting Synapse-associated protein 102, SAP-102, Discs large homolog 3, DLG3, NE-DLG Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Synapse-associated protein 102, SAP-102, Discs large homolog 3, DLG3, NE-DLG (also reported as Synapse-associated protein 102, SAP-102, Discs large homolog 3, DLG3, NE-DLG).
- Immunogen/epitope region: N-terminal domain.
- Homology note: Rat, mouse - 26/32 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Mouse.
- 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.
- 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
SAP-102 (also known as DLG3) 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.SAP-102 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. Moreover, mutations in the SAP102 gene have been linked with a form of mental retardation3.
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.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
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-PZ003.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
