GLUT 1 (Glucose Transporter 1)

Most mammalian cells transport glucose through a family of \nmembrane proteins known as glucose transporters. Molecular \ncloning of these glucose transporters has identified a family of \nclosely related genes that encodes at least 7 proteins (Glut-1 to \nGlut-13, Mol. Wt. 40-80kD) and sodium glucose co-transporter- 1 (SGLT-1, 662aa; ~75kD). Individual member of this family have identical predicted secondary structures with 12 transmembrane domains. Both N and C-termini are predicted to be cytoplasmic. Most differences in sequence homology exist within the four hydrophilic domains that may play a role in tissue- specific targeting. Glut isoforms differ in their tissue expression, substrate specificity and kinetic characteristics. Glut-1 mediates glucose transport into red cells, and throughout the blood brain barrier, and supply glucose to most cells. \n\nApplications: \nSuitable for use in ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilutions: \nWestern Blot: 1-10ug/ml using ECL. Identifies a major band at about 42-45kD from purified rat brain membranes.\nELISA: 0.5-1ug/ml. Control peptide can be used to coat ELISA plates at 1ug/ml.\nOptimal dilutions to be determined by the researcher.\n\nRecommended Control Peptide: \nG3900-05L: GLUT 1 (Glucose Transporter 1) Control Peptide\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile ddH2O or PBS. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Additional Info

Recognizes human GLUT 1 (Glucose Transporter 1). Antibodies made to this sequence from this region have detected Glut-1 from human (RBC) and rabbit brain and mouse 3T3 L1 fibroblasts and rat brain adipocytes. It also recognizes the Hep G2 type transporter and Glut-1 from Caco-2 cells (3).
