Overview
Anti-CD63 (extracellular)-PE Antibody is an antibody targeting Tetraspanin-30, TSPAN30, Lysosomal-Associated Membrane Protein 3, LAMP-3, Granulophysin, Melanoma-Associated Antigen ME491 Polyclonal raised in Rabbit (R-Phycoerythrin (R-PE)). This antibody is commonly used in FC, LCI to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Tetraspanin-30, TSPAN30, Lysosomal-Associated Membrane Protein 3, LAMP-3, Granulophysin, Melanoma-Associated Antigen ME491 (also reported as Tetraspanin-30, TSPAN30, Lysosomal-Associated Membrane Protein 3, LAMP-3, Granulophysin, Melanoma-Associated Antigen ME491).
- Immunogen/epitope region: Extracellular, 2nd loop..
- Homology note: Rat - identical Won't recognize CD63 from human samples (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- Lot quality control (as provided): Western blot analysis (unlabeled antibody, #ANR-210), and direct flow cytometry (labeled antibody)..
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
- Conjugate/format: R-Phycoerythrin (R-PE) (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
CD63, also known as Tetraspanin-30 (Tspan-30), lysosomal-associated membrane protein 3 (LAMP-3), lysosome integral membrane protein 1 (Limp1), melanoma-associated antigen (ME491), and ocular melanoma-associated antigen (OMA81H), is a multi-transmembrane protein that plays a role in cancer malignancy.1CD63 is a highly N-glycosylated member of the transmembrane-4 superfamily of tetraspanin proteins. CD63 is composed of 238 amino acids comprising four transmembrane α-helices, two extracellular loops, and a short cytoplasmic tail. CD63 is located in late endosomes, lysosomes, secretory vesicles, and the plasma membrane.
Research relevance and current trends
- Profiling immune-marker expression across cell subsets with single-cell or flow-based readouts.
- Connecting receptor/ligand levels to activation state and cytokine programs.
- Applying genetic perturbation or orthogonal assays to support specificity and interpretation.
Common research applications
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- 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: RIC-001-PE.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
