Sigma-Aldrich and Kraig Biocraft Laboratories Successfully Negotiate License Agreement

Sigma-Aldrich and Kraig to Work Together to Create the Next Generation Biomaterials

Sigma-Aldrich Becomes Kraig Shareholder

LANSING, MI--(Marketwire - Apr 12, 2011) - Kraig Biocraft Laboratories, Inc. (PINKSHEETS: KBLB) announced today that the Company has entered into a licensing agreement with biotechnology giant Sigma-Aldrich (NASDAQ: SIAL), Inc.

Kraig has successfully negotiated a license to use Sigma-Aldrich's powerful zinc finger technology to accelerate its scientific research and product development, along with an option to commercialize the resulting biomaterials in the textile and biomedical fields.

Under the terms of the agreement announced today, Sigma will provide Kraig with its proprietary genetic engineering tools and expertise in zinc finger nuclease to enable Kraig to significantly accelerate its product development. In addition to providing the customized tools and technological know-how, Sigma has granted Kraig an option for a commercial license to use the technology in the textile and biomedical markets. Sigma has agreed that upon exercise of the option Kraig will have exclusive commercial rights to use Sigma ZFNs in conjunction with the insertion of more than two hundred proprietary spider silk sequences previously licensed by Kraig from a third party into the silkworm genome. Sigma-Aldrich will be creating customized zinc fingers for Kraig's use in its development of spider silk polymers and technical textiles.

"Sigma-Aldrich's proprietary zinc finger technologies are extremely powerful tools which enable very precise genetic targeting," said Kraig's CEO Kim Thompson. "We are convinced that this technology is the key to creating advanced new products and materials. We believe that when these customized tools are delivered by Sigma in the coming weeks, the technology will enable us to rapidly and precisely target specific gene sequences for the creation of stronger fibers, advanced textiles and new bio-materials."

"ZFN technology has been revolutionary in genome engineering for various applications, including animal models of disease, engineering of biopharmaceutical production systems, academic research and therapeutics," said Dr. Joseph Bedell, Director of Sigma's Commercial Animal Technology Group. "Spider silk production is just the first example of a commercial animal application for this exciting technology."

"Kraig has the utmost confidence in the power of Sigma's zinc finger technology," said Mr. Thompson. "Sigma's agreeing to provide this technology by virtue of the licensing agreement to Kraig, is a real boost for us, and for the future of bio-materials and spider silk technology. We negotiated this agreement not only to accelerate our development of advanced materials, but also because I believe that Sigma's zinc finger technology will reinforce Kraig's competitive advantage in the field of bio-materials and advanced silk polymers. Kraig Biocraft Laboratories expectation is that the combination of Sigma-Aldrich's revolutionary technology and know-how, coupled with Kraig's proprietary bio-materials technology and know-how, will create synergies that will benefit both companies.
