THE FINE STRUCTURE OF SILK FIBROIN [PDF]

The Journal of Cell Biology, 1967
The fine structure of Bombyx mori silk fibroin was investigated by electron microscopy and X-ray diffraction techniques. Examination of silk fibers fragmented with ultrasonic radiation and negatively stained revealed the presence of ribbon-like filaments of well-defined lateral dimensions. Analysis of the breadths of the equatorial reflections in the X-

Recapitulating Endochondral Ossification for Bone Repair: From Development to Engineering Strategy

Advanced Healthcare Materials, EarlyView.
This review summarizes the developmental basis of endochondral ossification (ECO) and its applications in bone tissue engineering (BTE). It first outlines the key biological processes and signaling pathways underlying ECO, then discusses biomaterial‐based engineering strategies derived from these principles, and finally highlights future directions for

Functional material features of Bombyx mori silk light versus heavy chain proteins [PDF]

, 2015
Bombyx mori (BM) silk fibroin is composed of two different subunits; heavy chain and light chain fibroin linked by a covalent disulphide bond. Current methods of separating the two silk fractions is complicated and produces inadequate quantities of the ...

Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.

Gelation of silk fibroin.

Sen'i Gakkaishi, 1990
Refined silk fibroin obtained from waste cocoons was dissolved in a mixture of ethanol and neutral salt (calcium chloride) solution and the solution thus obtained was centrifuged and then acidified with an organic acid after dialysis. The pH of the resulting solution was in the acid side of the isoelectric point (pl=3.8-3.9).

Vortex-Induced Injectable Silk Fibroin Hydrogels [PDF]

Biophysical Journal, 2009
A novel, to our knowledge, technique was developed to control the rate of beta-sheet formation and resulting hydrogelation kinetics of aqueous, native silk solutions. Circular dichroism spectroscopy indicated that vortexing aqueous solutions of silkworm silk lead to a transition from an overall protein structure that is initially rich in random coil to

Functionalization of silk fibroin through anionic fibroin derived polypeptides

Frontiers in Bioengineering and Biotechnology, 2016
While silk fibroin (SF)-based fibrous matrices are often considered as templates to mimic the native biomineralization process, their limited ability to induce apatite deposition hinders their potential applications in bone tissue engineering. In this study, it was hypothesized that the incorporation of anionic fibroin derived polypeptides (Cs ...
