Agonist/Antagonist Uptake Assay Services
Creative Biolabs' [3H]-2-deoxy-D-glucose uptake assay service evaluates glucose transporter activity in rat cell models. This robust method quantifies the cellular uptake of the radiolabeled glucose analog to determine the functional effects of test compounds. The service efficiently profiles potential agonists and antagonists, providing critical data on their ability to modulate glucose transport. This enables the pharmacological characterization of novel therapeutics targeting metabolic pathways, with protocols optimized for high sensitivity and reproducibility to ensure reliable results for drug discovery and development.
Targeting Key Transporter Families and Regulatory Compliance
[3H]-2-deoxy-D-glucose (2-DG) is a radiolabeled glucose analog used to study glucose transport in rat models. It enters cells via specific GLUT transporters (GLUT1-4) but, unlike glucose, cannot be fully metabolized. After cellular uptake, it is phosphorylated and trapped as 2-DG-6-phosphate, allowing quantitative measurement of accumulated radioactivity. This reflects the rate of glucose transporter activity under various physiological or pathological conditions. The assay is widely applied to evaluate insulin sensitivity, drug effects, and metabolic disorders such as diabetes and cancer, where altered glucose metabolism is a key feature.
