Abstract The development of a method for the quantitative determination of the sericin content ratio (SCR) is urgently
needed for silk refining and the purification of silk fibroin for biomedical applications. In this work, a series of
sericin/fibroin mixed samples with known SCRs were prepared by mixing initial samples of extracted sericin
and fibroin from Bombyx mori silk. Significant differences were found in the contents of characteristic hydrophilic
amino acids abundant in sericin and hydrophobic amino acids abundant in fibroin, and several linear relationships of SCR associated with the content ratios of Ser/Ala, Asp/Ala, Lys/Ala, Asp/Gly and Ser/Gly were established by… More >
