I found a website that actually sells the biocable:
http://biothread.webstarts.com/ It's $900 a bottle(which I think is a rip off). Anyway, I think Peter made the webbing from scratch. I think he used Richard parker's notes, and used it to make them. Like in the ultimate spider man comics, richard was working on a molecular adhesive, aka, webbing. I think he uses his fathers notes on the biocable, the only modifications he made was making them into pellets and adding a chemical to loosen the fibers to shoot a mist. If I'm wrong, it was probably given to him as a gift from dr. Connors for helping him with lizard regeneration formula.
