General description: Sericin is a protein derived from the silkworm cocoon and has a number of beneficial characteristics for culturing mammalian cells. It has cryoprotective properties that allow for replacement of FBS in cryopreservation media. 1% sericin (w/v) along with 0.5% (w/v) maltose, 0.3% (w/v) proline, 0.3% (w/v) glutamine and 10% DMSO is comparable to 90% FBS and 10% DMSO1. Furthermore, sericin can act as a FBS replacement in cell culture and stimulate cell growth2,3 and in certain situations, inhibit cell death4.
Empirical Formula (Hill Notation): C6H3ClN2O4
