I was talking more about his comment “the gene is not as stable as we would like … after several generations the amount of spider protein starts to drop.”
I did not know about the issue with cytotoxins. I was under the impression that standard silkworm silk is perfectly compatible with humans since other companies such as Oxford Biomaterials and their offshoots have been working on using standard silk in medical applications. Does this only happen with worms that feed on mulberry or does it happen to the ones on the "silkworm chow mix" as well?
