Tested Applications

• Positive WB detected in: unboiled HT-29 cells, 37°C incubated mouse colon tissue
• Positive IHC detected in: rat brain tissue, human lung cancer tissue, human cervical cancer tissue, human breast cancer tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive IF-P detected in: mouse brain tissue
• Positive IF/ICC detected in: HeLa cells
• Positive FC (Intra) detected in: HeLa cells

For optimal WB detection with 21829-1-AP, we recommend to avoid boiling the sample after lysis.

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:8000
• Immunohistochemistry (IHC): IHC : 1:2500-1:10000
• Immunofluorescence (IF)-P: IF-P : 1:1000-1:4000
• Immunofluorescence (IF)/ICC: IF/ICC : 1:200-1:800
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.40 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

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.
