STUDIES ON SILK FIBROIN. III. GEL FILTRATION STUDY OF FIBROINS
International Journal of Peptide and Protein Research, 1974Silk fibroin samples obtained by extraction of silk fibre with boiling, Na2CO3 solution for different intervals of time were examined in 6M guanidine hydrochloride solution by gel filtration on agarose. All the samples studied were heterogeneous. The weight‐average molecular weight of the samples estimated by gel filtration method was lower than that

Publisher Summary Fibroins are regarded as protein filaments produced by certain species belonging to the classes Insecta (insects) and Arachnida (spiders, etc.). In the class Insecta, many species produce long silken filaments to form substantial cocoons in which they pupate. The classic example is the silkworm of commerce Bombyx mori (B.

STUDIES ON SILK FIBROIN. II. SEDIMENTATION COEFFICIENT DISTRIBUTION OF FIBROINS
International Journal of Peptide and Protein Research, 1973The sedimentation coefficient distributions of silk fibroin samples prepared by extraction of silk fibre by boiling Na2CO3 solution for different intervals of time were determined. Samples from 150 and 180 min extraction gave sharper distribution curves than those from 30, 60, 90 and 120 min extraction.

The biocompatibility of silk fibroin films containing sulfonated silk fibroin
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005AbstractSulfonation reaction may be an effective method for preparation of heparin‐like materials. However, no sulfonated polymer based on protein backbone was used for improving the blood compatibility of biomaterials. In this study, the biocompatibility of new kind of composite materials films obtained by blending silk fibroin (SF) with sulfonated ...

Stretchable silk fibroin hydrogels
International Journal of Biological Macromolecules, 2020Hydrogels derived from silk fibroin (SF) are attractive soft materials in biomedical applications such as drug delivery and tissue engineering. However, SF hydrogels reported so far are generally brittle in tension limiting their load-bearing applications. We present here a novel strategy for preparing stretchable SF hydrogels by incorporating flexible

Silk fibroin for vascular regeneration
Microscopy Research and Technique, 2015ABSTRACTCardiovascular disease is the primary cause of morbidity and mortality in today's world. Due to the lack of healthy autologous vessels, more tissue‐engineered blood vessels are needed to repair or replace the damaged arteries. Biomaterials play an indispensable role in creating a living neovessel with biological responses. Silk fibroin produced

An investigation of the structure of silk fibroin
Biochimica et Biophysica Acta, 1955Abstract An investigation based on new X-ray diffraction data, including quantitative spectrometric measurements of X-ray intensities, has led to the derivation of the fundamental structural features of silk fibroin. The structure consists of extended polypeptide chains bonded together by lateral N—H…O hydrogen bonds to form antiparallel-chain ...

Silk Fibroin in Tissue Engineering
Advanced Healthcare Materials, 2012AbstractTissue engineering (TE) is a multidisciplinary field that aims at the in vitro engineering of tissues and organs by integrating science and technology of cells, materials and biochemical factors. Mimicking the natural extracellular matrix is one of the critical and challenging technological barriers, for which scaffold engineering has become a ...

In vitro degradation of silk fibroin
Biomaterials, 2005A significant need exists for long-term degradable biomaterials which can slowly and predictably transfer a load-bearing burden to developing biological tissue. In this study Bombyx mori silk fibroin yarns were incubated in 1mg/ml Protease XIV at 37 degrees C to create an in vitro model system of proteolytic degradation.
