LANSING, Mich., Sep 10, 2013 (GLOBE NEWSWIRE via COMTEX) -- Kraig Biocraft
Laboratories, Inc. (OTCQB:KBLB) ("Company"), the leading developer of advanced
spider silk based fibers, today announced that the Company's initial testing of
its recombinant spider silk, Big Red, indicate that the Company's new
recombinant fiber is stronger than Monster Silk(R). The testing indicates that
Big Red's strength, as measured by the ultimate load it can withstand before
breaking, is approaching that of natural spider silk.

"These initial testing results appear to confirm the effectiveness of our design
approach with Big Red," said Company founder and CEO, Kim K. Thompson. "Big Red
was designed to be even stronger than our breakthrough product, Monster
Silk(R)," continued Thompson. "If the follow on testing confirms these results,
Big Red will be a significant breakthrough for our Company and for material
science."

"So far, Big Red has met or exceeded our expectations and design parameters. Our
plan is for Big Red to follow Monster Silk(R) in our commercialization ramp up."
