Advancements in Labeled Peptide Synthesis: Strategies for Incorporating Biotin, FITC, and Other Tags

Last Updated: February 27, 2026

The synthesis of labeled peptides, such as those tagged with biotin, FITC, or nanoparticles, plays a crucial role in a wide range of research applications, including binding studies and receptor cross-linking investigations. A novel strategy for producing these peptides involves...

Why is conjugation of the peptide to a carrier protein necessary?

Last Updated: February 27, 2026

The process of linking a peptide to a carrier protein is a foundational technique in vaccine development and antibody production, enhancing the overall efficacy and response of the immune system to the antigen. This conjugation serves multiple critical functions in...

To save cost, can I split the purified peptide so that half is labeled with biotin and the remaining left unlabeled

Last Updated: February 27, 2026

Can you split the purified peptide so that half the sample could be labeled with a biotin tag and the remaining is left unlabled. Do I need to quote for two peptides? This is for N terminal labeling. The label...
