Kraig Labs Scales Spider Silk Production with Genetically Engineered Silkworms
Event summary
- Kraig Labs deployed 1 million genetically engineered silkworm eggs across multiple Vietnamese facilities to produce 10 metric tons of spider-silk cocoons monthly.
- The company is preparing initial shipments of biodegradable recombinant spider silk to unannounced global brands for pilot development programs.
- Spider silk produced by transgenic silkworms has tensile strengths approaching 1.8 gigapascals and elasticity above 38%.
- Kraig Labs is exploring a genetic design using sequences from the Darwin’s bark spider to produce fibers composed largely of spider silk proteins.
The big picture
Kraig Labs is attempting to turn spider silk from a laboratory material into a commercially manufactured fiber by combining traditional sericulture with modern gene-editing techniques. This approach could represent one of the few examples of a transgenic animal system used for commercial manufacturing outside pharmaceuticals. The company's success could pave the way for other high-performance, sustainable biomaterials.
What we're watching
- Production Scaling
- The pace at which Kraig Labs can maintain industrial-scale production of spider silk will determine its commercial viability.
- Market Adoption
- Whether global brands will integrate Kraig Labs' spider silk into their products will be a key indicator of market acceptance.
- Technological Advancements
- The success of Kraig Labs' efforts to replace silkworm silk genes with spider-silk genes will impact the purity and performance of the final product.
