We are able to incorporate a wide range of labels into peptides that we synthesis. Please don't hesitate to get in contact with us to discuss your requirements. We have listed only a small handful of the available options here.
Incorporating fluorescent probes is a popular option. For example: FAM (fluoroscein); TAMRA (carboxytetramethylrhodamine) which is more stable than fluoroscein; Dansyl; and Dabcyl.
The most popular affinity tags we incorporate into peptides are biotin and desthiobiotin.
