Leading silk company, Kraig, has announced at a recently press conference that it has successfully developed a new technology platform, based on a non-CRISPR gene editing knock-in knock-out technology. Other than the silkworm’s remaining specifically desired native silk protein elements, the company is now able to produce nearly pure spider silk.

The new technology has a purity rate that is about ten times greater than dragon silk, a fibre that the company developed with its previous tools. Dragon silk has already demonstrated to be tougher than many fibres used in bullet proof vests and the company expects that the increased spider silk purity, created using this new approach, will yield materials beyond those capabilities, according to Kraig.

The new system utilises the company’s eco-friendly and cost effective silkworm production system, which is significantly more advanced than any of the competing methods. The company’s knock-in knock-out technology allows Kraig labs to work with very complex protein sequences in silkworm, which are about four times more complex than published technologies.

Ambitious immunity boosting programme will benefit not only the company’s proprietary transgenics, but will help strengthen production for mundane silk market, which is a $5 billion a year industry. The new technology, which is the result of over ten years of effort, hits the target of one of the company’s primary technological goals and opens the door for large scale US production.

The new technology has applications and implications far beyond material performance. The company is now well underway, and rapidly advancing, t efforts to enhance its silkworm technology to allow for large scale US production. The company has already begun the validation process for the first of these new transgenics and anticipates that US production to be possible as early as 2022 or 2023.
