N-formyl-Nle-Leu-Phe-Nle-Tyr-Lys (trifluoroacetate salt)

N-formyl-Nle-Leu-Phe-Nle-Tyr-Lys (fNLFNYK) is a synthetic chemotactic peptide. It binds to the formyl peptide receptor (FPR, Kd = 2.2 nM). fNLFNYK has been conjugated to various fluorophores to monitor FPR internalization.Formal Name: N-formyl-L-norleucyl-L-leucyl-L-phenylalanyl-L-norleucyl-L-tyrosyl-L-lysine, monotrifluoroacetate salt.
