Rat tail collagen type I

Collagen is the major extracellular matrix in mammalian tissue, therefore purified collagen has a wide variety of applications in medical and life science research, including tissue/cell culture, tissue engineering, tissue 3D scaffold, medical devices, tissue reconstruction and tissue repair

L929 cell line 2D and 3D culture with Rat tail collagen (10X)

Rat tail collagen type I from Expercy is purified from the tails of no medication laboratory rats and provides researchers with reliable and high-quality collagen for cell culture and tissue engineering. We provide rat tail collagen at concentration of 3 or 10 mg/ml and can dilute to lower concentration depends on needs.


  • Mimicking in vivo-like ECM environment.
  • Quick polymerization helps optimal cell distribution in 3D gels.
  • High purity and lot-to-lot consistency.
  • Various concentration available for a variety of applications.
