Description
N-formyl-methionyl-leucyl-phenylalanine (fMLF) is a formylated tripeptide produced by certain types of bacteria. Also known as the chemotactic bacterial peptide, the fMLF peptide is a strong leukocyte chemoattractant that interacts with the human N-formyl peptide receptor (FPR) and the N-formyl peptide receptor-1 (FPRL1).

Characteristics
fMLF peptide is a well-characterized peptide that has been widely used to develop solid state NMR methods. It has various amazing characteristics that allow us to promote this peptide as a great Solid-State NMR standard for all the laboratory that works in solid state, such as:
  • S/N hundreds of times more favorable with respect to the most common and widely used protein standards.
  • Fast and accurate sequence set-up.
  • Highly favorable relaxation times, T1 comparable with those of proteins.
