Recombinant Human
Collagen Type I
Collagen is the primary building block of the human body. Its biocompatibility, biodegradability and low
immunogenicity make it an ideal choice for pharmaceutical and biotechnological applications. Collage™,
the first plant-derived source of type I recombinant human collagen, offers excellent homogeneity,
contouring abilities and scaffolding properties.

                                                        Virgin collagen, Collage™, forms naturally smooth
           Manufacturing Process                        and homogenous fibrils that create an excellent
                                                        scaffold for cellular proliferation, differentiation
              Cultivation of bio-engineered plants      and tissue repair. Grown in bioengineered
                                                        plants rather than processed from recycled
               Harvesting leaves                        animal tissues, Collage™ has an enhanced safety
                                                        profile and is a natural match for human culture
                 Preliminary recovery process
       Protein extraction and purification              Collage™ is inherently free of animal and human-
                                                        derived components, such as cytokines, hormones,
                 Pharmaceutical grade collagen          growth factors, or other types of human or animal-
                                                        derived pathogens.

 Collage™ can be fabricated
 into 3-dimensional scaffolds
 and used for tissue culture,
 and animal studies
 Collage™ unique production process allows for precise manipulation of the crosslinks that bind the
 collagen fibrils into their functional forms. Controlling their mechanical strength and degradation
 rate, CollPlant achieves the optimal functional form for each given application. Collage™ can also be
 combined with other biomaterials to form composite devices.
 Some functional forms include sponges, sheets, membranes, films, gels and fibers.
