Immunogen
Peptide (C)KEFINKTLTDKGN, corresponding to amino acid residues 39-51 of human GLUT3 (Accession P11169). 1st extracellular loop.
Accession (Uniprot) Number P11169
Gene ID 6515
Peptide confirmation Confirmed by amino acid analysis and mass spectrometry.
Homology 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 94.5% amino acid identity to GLUT3.
Specificity The antibody will not recognize rat or mouse GLUT3.
Label Fluorescein isothiocyanate (FITC)
Storage before reconstitution The antibody ships as a lyophilized powder at room temperature. Upon arrival, it should be stored at -20°C.
Reconstitution 15 µl or 50 µl double distilled water (DDW), depending on the sample size.
Storage after reconstitution The reconstituted solution can be stored at 4°C, protected from the light, for up to 1 week. For longer periods, small aliquots should be stored at -20°C. Avoid multiple freezing and thawing. Centrifuge all antibody preparations before use (10000 × g 5 min).
Standard quality control of each lot Western blot analysis (unlabeled antibody, #AGT-043), and direct flow cytometry (labeled antibody).
Applications: fc
May also work in: ic*, lci*

Cell surface detection of GLUT3 in live intact human THP-1 monocytic leukemia cells:
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. It is predominantly expressed in neurons and is commonly called “neuronal glucose transporter". The protein contains 12 membrane-spanning domains, an N-linked glycosylation site in loop 1 responsible for high-affinity transport of glucose, and intracellular NH2- and COOH- termini. In addition, there are several conserved residues and motifs designated “sugar transporter signatures”1,2.
GLUT3 levels are high in some malignant glioma cells compared to normal glial cells and therefore may be used as a therapeutic target in some cancer treatment3.
