Labeled Peptides

Custom Peptide Synthesis

Labeled peptides are peptides covalently conjugated with fluorophores, biotin or other modifications. They are commonly used to monitor the in vivo distribution and metabolism of specific peptides, with broad applications in fluorescence imaging, drug–receptor interaction studies, and pharmacokinetics.

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.
