It is modern day journalism. If 36% were only true. Shouldn't we be just a little skeptical of what we read?
Kraig Biocraft Laboratories achieves Knock-in Knock-out Success to create nearly Pure Spider Silk
They are just now announcing what we've had for nearly 3 and a half years. My guess is that we are close to 99% pure SS. The percentage not pure SS proteins is desirable for strength and elasticity properties.
Someone other than KBLB, has finally announced their strength numbers. 1.299 Mpa. As a reminder, even Dragon Silk is around 2 Mpa.
Now maybe it is time for Kim to announce what our nearly pure SS strength and elasticity numbers are.
