Overview
Anti-Human GLUT3 (extracellular)-FITC Antibody is an antibody targeting Glucose transporter 3, Facilitated glucose transporter member 3, SLC2A3 Polyclonal raised in Rabbit (Fluorescein isothiocyanate (FITC)). This antibody is commonly used in FC to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Glucose transporter 3, Facilitated glucose transporter member 3, SLC2A3 (also reported as Glucose transporter 3, Facilitated glucose transporter member 3, SLC2A3).
- Immunogen/epitope region: 1st extracellular loop.
- Homology note: Human only This antibody will also recognize the human paralog GLUT14 /SLC2A14 (Accession Q8TDB8) Homology - 12/13 amino acid residues identical The GLUT14 gene is specific to humans and has an overall 945% amino acid identity to GLUT3 (informative for cross-species interpretation).
- Species reactivity (as provided): Human.
- Specificity statement (as provided): The antibody will not recognize rat or mouse GLUT3..
- Lot quality control (as provided): Western blot analysis (unlabeled antibody, #AGT-043), 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.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
The GLUT protein family is encoded by the SLC2 genes and is a member of the major facilitator superfamily of membrane transporters. GLUTs are recognized as key regulators of whole-body glucose homeostasis, and are responsible for the uptake of carbohydrate-derived glucose by cells. There are 14 GLUT isoforms divided into 3 different group classes based on sequence similarity and structural and functional characteristics1,2.GLUT3 is a low-Km protein responsible for glucose uptake into neurons.
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
Common research applications
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
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-F.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
