And whereas spiders produce up to seven kinds of silk proteins, BioSteel, as yet, contains only one.

The genes caused the cells to produce silk proteins, which were collected and squeezed out a syringe into fibers.

In earlier experiments with bacteria and yeast, scientists were able to produce only a truncated, weaker silk protein.

Scientists do not fully understand how spiders spin their syrupy solution of silk proteins into threads.

While the silk proteins and orb-web spinning may be the same in both spider groups, their capture methods differ.

Made from silk protein, it makes hair shine like glass.

We milk Freckles together and process it in the lab to leave only the silk proteins.

Serine was first obtained from silk protein, a particularly rich source, in 1865.

Until now, scientists had decoded silk proteins from only four species of orb weavers.

In the new study, the Riverside and Wyoming researchers decoded silk proteins from another 10 spider species.
