Silk Fibroin (Bombyx mori silkworm)


Catalog #: P2010008 – 50 mg

Silk fibroin is an insoluble protein produced by Bombyx mori silkworm. It is the major component of the silkworm cocoon. Due to its unique structural properties, low immunogenicity and stability at low pH, Silk fibroin has several applications in both textile industry and biochemical research. Thaw slowly at 2-8 °C then swirl content to mix. Do not vortex.
