Labeled Peptides

Peptides labeled with biotin or fluorescein are used extensively in immunoassay, immunocytochemistry, and immunodetection. Our custom peptide synthesis group can help you design your labeled peptides. Depending on your application, the labeling can be done on the C- or N-terminus. An extended arm or spacer such as 6-aminohexanoic acid (LC) can be used to increase the distance between the labeling group and the peptide in order to preserve the immunoactivity of the peptide. We also synthesize peptides labeled with heavy isotopes, C13 and N15, which are commonly used for NMR studies.
