A synthetic cyclic peptide of seven amino acid residues. The ring is closed by a lactam bridge formed between two side chains, which constrains the backbone into a fixed conformation. That cyclisation is the principal structural difference from the linear 13-residue peptides of the same family, and it substantially increases resistance to exopeptidase cleavage, since the molecule presents no free N- or C-terminus of the usual kind.

COMPOSITION

Cyclic heptapeptide, side-chain lactam bridged · MW 1,025.2 g/mol · CAS 189691-06-3

ANALYTICAL SPECIFICATION

Identity confirmed by mass spectrometry against the theoretical molecular weight. Purity by reverse-phase HPLC at 214 nm, reported as area percent. Cyclic peptides give characteristically sharp chromatographic peaks relative to their linear counterparts. Each lot ships with a certificate of analysis matched to its lot number.

SUPPLY FORMAT

Supplied as a 10 mg vial, the standard size across this category, which makes the material directly comparable between suppliers.

FORM AND STORAGE

White to off-white lyophilized powder. Store lyophilized, protected from light. The tryptophan residue is light-sensitive; amber vial storage is recommended.

Supplied for laboratory research use only. Not for human or veterinary use. No preparation, measurement, handling or application instructions are provided.
