University of Notre Dame and Kraig Biocraft Laboratories Create Artificial Spider Silk Breakthrough

SOUTH BEND, IN, Sep 29, 2010 — Kraig Biocraft Laboratories, (OTCBB: KBLB ) is very pleased to announce that the following release was made by the University of Notre Dame moments ago.

Notre Dame and University of Wyoming scientists genetically engineer silkworms to produce artificial spider silk

A research and development effort by the University of Notre Dame, the University of Wyoming, and Kraig Biocraft Laboratories, Inc. has succeeded in producing transgenic silkworms capable of spinning artificial spider silks.

“This research represents a significant breakthrough in the development of superior silk fibers for both medical and non-medical applications,” said Malcolm J. Fraser Jr., a Notre Dame professor of biological sciences. “The generation of silk fibers having the properties of spider silks has been one of the important goals in materials science.”

Natural spider silks have a number of unusual physical properties, including significantly higher tensile strength and elasticity than naturally spun silkworm fibers. The artificial spider silks produced in these transgenic silkworms have similar properties of strength and flexibility to native spider silk.

Silk fibers have many current and possible future biomedical applications, such as use as fine suture materials, improved wound healing bandages, or natural scaffolds for tendon and ligament repair or replacement. Spider silk-like fibers may also have applications beyond biomedical uses, such as in bulletproof vests, strong and lightweight structural fabrics, a new generation athletic clothing and improved automobile airbags.

Until this breakthrough, only very small quantities of artificial spider silk had ever been produced in laboratories, but there was no commercially viable way to produce and spin these artificial silk proteins. Kraig Biocraft believed these limitations could be overcome by using recombinant DNA to develop a bio-technological approach for the production of silk fibers with a much broader range of physical properties or with pre-determined properties, optimized for specific biomedical or other applications.

The firm entered into a research agreement with Fraser, who discovered and patented a powerful and unique genetic engineering tool called “piggyBac.” PiggyBac is a piece of DNA — known as a transposon that can insert itself into the genetic machinery of a cell.

“Several years ago, we discovered that the piggyBac transposon could be useful for genetic engineering of the silkworm, and the possibilities for using this commercial protein production platform began to become apparent.”

Fraser, with the assistance of University of Wyoming researcher Randy Lewis, a biochemist who is one of the world’s foremost authorities on spider silk, and Don Jarvis, a noted molecular geneticist who specializes in insect protein production, genetically engineered silkworms in which they incorporated specific DNAs taken from spiders. When these transgenic silkworms spin their cocoons, the silk produced is not ordinary silkworm silk, but, rather, a combination of silkworm silk and spider silk. The genetically engineered silk protein produced by the transgenic silkworms has markedly improved elasticity and strength approaching that of native spider silk.

“We’ve also made strides in improving the process of genetic engineering of these animals so that the development of additional transgenics is facilitated,” Fraser said. “This will allow us to more rapidly assess the effectiveness of our gene manipulations in continued development of specialized silk fibers.”

Since silkworms are already a commercially viable silk production platform, these genetically engineered silkworms effectively solve the problem of large scale production of engineered protein fibers in an economically practical way.

“Using this entirely unique approach, we have confirmed that transgenic silkworms can be a potentially viable commercial platform for production of genetically engineered silk proteins having customizable properties of strength and elasticity,” Fraser said. “We may even be able to genetically engineer fibers that exceed the remarkable properties of native spider silk.”

The genetic engineering breakthrough was announced today (Sept. 29) by Dr. Fraser, Dr. Lewis and Kraig Biocraft CEO Kim Thompson at a press conference on the Notre Dame campus.
