AMSilk x 21st.BIO: taking spider silk to next level

Our collaboration with German biotech AMSilk, covered in Nature Biotechnology, is enabling the large-scale production of various spider silk proteins used in biomedical, cosmetics, and textile industries.

Our technology and expertise led to industry milestones:

  • world’s first extracellular expression of spider silk proteins, enabling scalable production
  • production upscaling to unprecedented levels, opening a middle-value market to expand accessibility

For its unparalleled combination of strength and flexibility, spider silk is the gold standard of bioindustrial materials. Not only is biosilk produced via precision fermentation mechanically superior, it is also fully biocompatible. It has unlimited applications ranging from biofilms, home textiles, footwear, bags, and even composites for automobile.

We are very proud to continue supporting AMSilk in leading the field with industrial scale supplies of high-performance materials.

By partnering with 21st.BIO, we are succeeding where so many have struggled, delivering high performance precision fermentation at the right quality and cost parameters, and at a true industrial scale.
