Overview
Anti-DSCAM (extracellular) Antibody is an antibody targeting Down Syndrome Cell Adhesion Molecule, DS Cell Adhesion Molecule, CHD2 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Down Syndrome Cell Adhesion Molecule, DS Cell Adhesion Molecule, CHD2 (also reported as Down Syndrome Cell Adhesion Molecule, DS Cell Adhesion Molecule, CHD2).
- Immunogen/epitope region: Extracellular, N-terminus..
- Homology note: Rat - identical, Human - 15 out of 17 amino acid residues 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
Down syndrome cell adhesion molecule, DSCAM, also known as CHD2, is a member of the immunoglobulin superfamily of cell adhesion molecules (Ig-CAMs). DSCAM is classified as a type I membrane protein with an extracellular domain consisting of ten immunoglobulin (Ig) and six fibronectin type III (FNIII) repeats and an intracellular domain that does not contain any identifiable motifs.1The gene coding for the DSCAM protein is located on the human chromosome 21, specifically in the so-called Down syndrome critical region (DSCR), the trisomy of which is considered a determinant for the intellectual disability associated with Down's syndrome. Therefore, the potential involvement of DSCAM in the developing neural system, has received considerable attention.2,3DSCAM is widely expressed in the vertebrate central nervous system where it plays a crucial role in neural development.
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.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
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-NR046.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
