Collink.3D 50L

What is Collink.3D 50L?

Collink.3D is the first and only plant-based human collagen bioink platform, mass produced at high consistency, enabling perfect mimicry of the native properties of tissues and organs.  
Collink.3D 50L is based on recombinant human type I collagen (rhCollagen), that was chemically modified to generate a curable bioink in a dry form, with approximately 50% of the primary amines converted into methacrylamides.

Biocompatible, non-immunogenic

What are the uses of Collink.3D?

Collink.3DTM enables fabrication of 3D constructs with complex architectures, meeting the demand for specific geometric, physical and biological properties. Biofabricated constructs made with Collink.3DTM can be used in a wide range of soft and hard tissue applications, including tissue models for drug discovery and screening, as well as the development and manufacture of tissue and organ transplants.

Owing to its cytocompatibility, Collink.3DTM supports significant high viability of various cell types – fibroblasts, stem cells, induced pluripotent stem cells, endothelial and epithelial cells.
