CCP (trifluoroacetate salt)

Cyclic citrullinated peptide (CCP) is a cyclic peptide that corresponds to amino acids 447-468 of human filaggrin but contains Q447H, S449C, G459R, E460G, S462C, and S468K substitutions and is citrullinated at arginine 455. This product can be used in the detection of anti-citrulline autoantibodies. Formal Name: ((4R,7S,13S,16S,19S,25S,28S,31S,34S,37S,40S,43R)-40-((1H-imidazol-4-yl)methyl)-43-((S)-5-amino-2-((S)-2-amino-3-(1H-imidazol-4-yl)propanamido)-5-oxopentanamido)-37-(3-amino-3-oxopropyl)-34-(2-carboxyethyl)-7,13,19-tris(3-guanidinopropyl)-28-((R)-1-hydroxyethyl)-16,31-bis(hydroxymethyl)-6,9,12,15,18,21,24,27,30,33,36,39,42-tridecaoxo-25-(3-ureidopropyl)-1,2-dithia-5,8,11,14,17,20,23,26,29,32,35,38,41-tridecaazacyclotetratetracontane-4-carbonyl)glycyl-L-arginyl-L-serylglycyl-L-seryl-L-lysine-2,2,2-trifluoroacetic acid.
