Fluorescent-labeled Peptides

Custom Peptide Synthesis

Fluorescently labeled peptides are peptides covalently conjugated with fluorescent dyes or luminescent moieties. They enable tracking and analysis of peptide distribution and dynamic metabolism in vitro or in vivo, leading to wide applications in receptor-binding studies and drug delivery monitoring.

    Semaglutide, FITC labeled 99.83%
    Semaglutide, FITC labeled is a long-acting, selective, competitive GLP-1R agonist that can penetrate the blood-brain barrier. After activating GLP-1R, Semaglutide, FITC labeled promotes insulin secretion, inhibits gastric emptying and appetite, and at the same time enhances autophagy, inhibits oxidative stress and apoptosis. Semaglutide, FITC labeled also regulates mitochondrial function and lipid metabolism (such as reducing de novo lipogenesis in the liver). Semaglutide, FITC labeled has activities such as lowering blood sugar, reducing weight, neuroprotection (such as improving motor function in Parkinson's disease models, reducing α-synuclein aggregation) and improving hepatic steatosis. Semaglutide, FITC labeled can be used for the study of neurodegenerative diseases and liver diseases such as type 2 diabetes, obesity, Parkinson's disease, metabolic associated fatty liver disease (MASLD), and cancer.
