| GLUT1

Glucose transporter 1 (or GLUT1), also known as solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1), is a uniporter protein that is encoded by the SLC2A1 gene. GLUT1 facilitates the transport of glucose across the plasma membranes of mammalian cells. This gene encodes a facilitative glucose transporter that is highly expressed in erythrocytes and endothelial cells, including cells of the blood–brain barrier. The encoded protein is found primarily in the cell membrane and on the cell surface, where it can also function as a receptor for human T-cell leukemia virus (HTLV) I and II.[3] GLUT1 accounts for 2 percent of the protein in the plasma membrane of erythrocytes.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	80	40	20	10	5	2.5	1.25	0
OD	2.05	1.5	0.99	0.66	0.45	0.33	0.24	0.08
Corrected OD	1.97	1.42	0.91	0.58	0.37	0.25	0.16	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Rat GLUT1 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	92-104	101
Cell Lysates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Rat GLUT1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	87-96	90-110
	Average (%)	91	98
1 : 4	Range (%)	87-108	105-115
	Average (%)	96	111
