CELLINK PCL is a high molecular weight (Mn 50,000) thermoplastic linear polyester derived from caprolactone monomer. This biodegradable polyester has a melting point of 60°C. CELLINK PCL can be used as a support to provide a re-enforcing structure when bioprinting load-bearing tissue constructs, such as bone grafts or osteochondral plugs, for in vitro and in vivo studies. It can also be used as a support material to provide a temporary scaffold for overhanging structures during 3D bioprinting. Supplied in granular form (3 mm pellets).
