Common Name(s): Atelocollagen,atelocollagen,telopeptide-removed purified collagen,low immunogenicity skin conditioner

CAS Number: N/a

DESCRIPTION

What It Does: Provides collagen conditioning, fibroblast receptor-stimulated collagen synthesis, and wound healing activity from the intact triple-helix while minimising the immunogenic telopeptide-mediated hypersensitivity associated with native collagen.

Why It's Used: Atelocollagen is the gold standard collagen for cosmetic and medical applications — pepsin treatment selectively removes the non-helical telopeptide regions (primary immunogens) while preserving the biologically active triple-helical domain and rgd-sequence fibroblast receptor binding.

How It Works: Pepsin digestion cleaves collagen at asp/glu residues flanking the telopeptide n- and c-terminal non-helical regions — removing the major t-cell epitopes responsible for allergic sensitisation. the remaining triple-helix retains: rgd integrin binding sequences → fibroblast collagen synthesis stimulation; gfoger sequences → mmp-2 activation for ecm remodelling; hydroxyproline-dense sequences → sc protein conditioning.

SCIENTIFIC NOTE

Atelocollagen provides significantly reduced allergenicity versus native collagen: the telopeptide removal reduces ige-mediated reactivity by >90% in sensitised individuals — preferred for cosmetics targeting users with potential collagen hypersensitivity.
