Sericin Proteins of Different Lengths.
The silk fibers were made free of
sericin and proven as non cytotoxic.
Studies have been carried out with silk protein
sericin for the development of water-selective membrane blends crosslinked with DMU, which have led to a high water selectivity in the pervaporation process [8].
Sericin was a kind of natural material that had long been taken as waste in silk reeling industry.
mori cocoons were boiled twice in 0.5 wt% [Na.sub.2]C[O.sub.3] solution to remove
sericin. Degummed silks were then dissolved in 9.0 M LiBr aqueous solution at 40[degrees]C for 2h and further dialyzed in deionized water at 10[degrees]C for 3 days according to the established procedures [19].
moil silk fibers were boiled three times, each time for 30 min in an aqueous solution of 0.05 wt% N[a.sub.2]C[O.sub.3], and rinsed thoroughly with deionized water to extract
sericin proteins.
Each silk fiber consists of two types of proteins; fibroin and
sericin. Silk fibroin (SF) is an insoluble fibrous component, whereas
sericin is a glue-like protein that is well soluble in hot water or some organic solvents.
GoBlond contains
sericin and fibroin proteins combined with vegetable polysaccharides to protect the integrity of the hair structure during the bleaching process.
Silk filament is a double strand of fibroin, which is held together by a gummy substance called silk
sericin or silk gum [15].
Natural silk consists primarily of two kinds of proteins: silk fibroin (SF) and
sericin (gum), which form two cores and protective outlayer of silk fiber.
