N-Formyl Peptides (fMLF / fMLP) — frequently asked
What are N-formyl peptides?
They are short peptides bearing a formyl group on the N-terminal methionine, a signature of bacterial and mitochondrial protein synthesis. N-formyl-Met-Leu-Phe, written fMLF or fMLP, is the prototype and remains the most widely used member of the group.
Why are they studied?
Formyl peptides are classical chemoattractants for the formyl peptide receptor family, especially FPR1 and FPR2 on neutrophils and monocytes. They are used to trigger and quantify migration, calcium flux, degranulation and oxidative burst responses in innate immunity experiments.
Why are so many sequence variants listed?
Receptor potency and selectivity depend sharply on residue identity and order, so a series of positional variants supports systematic structure-activity work. Boc-protected forms such as Boc-Phe-Leu-Phe-Leu-Phe are commonly used as antagonists to confirm that responses are receptor-mediated.
