Specificity / Sensitivity

Glut3 (E7M7V) Rabbit mAb recognizes endogenous levels of total Glut3 protein. This antibody does not cross-react with Glut1, Glut2, or Glut4.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala472 of human Glut3 protein.

Background

Glucose transporter 3 (Glut3, also known as SLC2A3) has a higher affinity for glucose than the ubiquitous glucose transporter Glut1. In the normal brain, Glut3 expression is limited to neurons, whereas Glut1 is expressed in both neurons and glia. Glioblastoma-derived brain tumor initiating cells (BTICs) express increased levels of Glut3, enabling their survival in the microenvironment deficient in glucose. In addition, Glut3 expression levels correlate with poor survival in brain tumors (1). Furthermore, integrin αvβ3 was shown to stimulate PAK4-YAP/TAZ signaling to upregulate Glut3 expression in glioblastoma cells. A subpopulation of glioblastoma was identified to be addicted to Glut3 and is highly sensitive to the disruption of integrin αvβ3-PAK4-YAP/TAZ signaling (2,3).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Western Blotting Image 1: Glut3 (E7M7V) Rabbit mAb Expand Image
Western blot analysis of membrane/organelle fraction extracts from SW480 and OVCAR-4 cells using Glut3 (E7M7V) Rabbit mAb (upper) and Na,K-ATPase α1 (D4Y7E) Rabbit mAb #23565 (lower). The difference in Glut3 expression levels detected in SW480 and OVCAR-4 extracts is consistent with both RNAseq and proteomic expression profiling data, confirming specificity of the antibody for Glut3.
