Background Information
Glucose transporter 1 (GLUT1), also known as solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1), is a uniporter protein responsible for the transport of glucose in many cell types and across the blood-brain barrier.
What is the molecular weight of GLUT1? Is GLUT1 post-translationally modified?
There are two forms of GLUT1 transporter that differ in their molecular weight. The 45-kDa form is found in glial cells, while the 55-kDa form is present in the endothelial cells regulating glucose transport over the blood-brain and blood-tissue barriers (PMID: 9630522). N-glycosylation of asparagine at position 42 is the only known post-translation modification of GLUT1 (PMID: 3839598).
What is the subcellular localization of GLUT1?
Glucose transporters, including GLUT1, are multiple-pass integral membrane proteins. GLUT1 is present at the plasma membrane but is also a subject of recycling between plasma membrane and endosomes.
What molecules can be transported by GLUT1?
The main substrate of GLUT1 transport is glucose, but it can also transport galactose, mannose, glucosamine, and reduced ascorbate.
What is the tissue expression pattern of GLUT1?
GLUT1 is expressed by many cell types but the highest levels are observed in erythrocytes and in the central nervous system (astrocytes). GLUT1 is responsible for glucose transfer across the blood-brain and blood-tissue barriers, including placental transport.

Reviews
What customers say
Both reviewers used this antibody for Western Blot and reported only moderate performance. One user noted the signal was weak with a not-very-clean background when used at 1:1000 on HeLa cells, mouse liver, and mouse brain tissue. The other found the antibody worked "ok-ish" but required a higher concentration (1:500) than the recommended 1:1500–1:3000 range to visualize bands in fallopian tube epithelial cells. Overall, the antibody functions but may require optimization of dilution and conditions to achieve stronger, cleaner results.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Hua (Verified Customer) (09-06-2023) | Works ok in WB. Signal is weak and background is not very clean.
 |
Iru (Verified Customer) (04-23-2019) | This antibody works ok-ish, even though the protocol says use 1:1500 to 1:3000, I have to use 1:500 to see the bands.
