Glut1.RBD, glucose transporter(Glut1) 검출 및 정량용 ligand
Unique cell surface nutrient transporter ligands
Glut1.RBD는 세포표면의 주요 glucose transporter인 Glut1의 ligand로, Glut1의 검출과 정량에 사용 할 수
Glut1 (solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1)) is the major glucose
transporter. It is a key player of basal glucose metabolism, and as such can be dysregulated by conditions
triggering, or requiring, energetic modulations such as glucose starvation, malignancies etc.
HTLV2 is a human retrovirus that uses Glut1 as a receptor to bind, enter and infect cells through the use of
it’s envelope protein. This receptor binding domain (RBD) has been fused to an antibody Fc domain to
produce the Glut1.RBD, which can be utilised like an antibody to monitor Glut1 at the cell surface. More than
six RBDs have been designed this way
• Only cell surface Glut1 ligand
• Compatible with all human cell types
• Ideal for drug discovery & development
• Easy to use
• Provide optimized protocols
Glut1 is the major glucose transporter, and ASCT2 a critical glutamine transporter. Their cell surface
expression is a marker of Warburg effect due to mitochondrial defects, hypoxia or increased energetic
demand and is linked to many cancer pathways.
FLVCR1 is the only described heme exporter. RFT1/3 are two riboflavin transporters. They are involved in
oxidative stress mitigation.
Proliferation & adhesion
Pit1, Pit2 and XPR1 are inorganic phosphate transporters regulate phosphate homeostasis. They are involved
in cell proliferation and adhesion.

For flow cytometry experiment, you may also want to use the GFP-fused Glut1.RBD :
use it as a primary antibody and get results in a single labeling step !
