Kraig Biocraft Laboratories is poised to ramp up its production of spider silk-based fibers.

he U.S. biotechnology firm said Monday that it would open more than one additional production location, including domestic options, which would operate in parallel to its previously announced operation in Vietnam.

Known for achieving a series of material science breakthroughs using its genetic engineering technologies, such as the patent-pending Dragon Silk fiber it’s claimed is stronger and more flexible than native spider silk, Kraig’s plans for Vietnam—announced in March—include forming a subsidiary and opening an advanced hybrid silk research and pilot production plant there.

The firm said that additional sites will allow its labs to “more rapidly fulfill outstanding material requests” from both its collaboration partners and prospective clients for recombinant spider silk fibers.
