X-ray fiber diffraction modeling of structural changes of the thin filament upon activation of live vertebrate skeletal muscles
Thin filament Ca2+-regulation skeletal muscle X-ray fiber diffraction
2010/2/23
In order to clarify the structural changes of the thin filaments related to the regulation mechanism in skeletal muscle contraction, the intensities of thin filament-based reflections in the X-ray fib...
Actin oligomers at the initial stage of polymerization induced by increasing temperature at low ionic strength: Study with small-angle X-ray scattering
actin trimer X-ray scattering solution structure oligomer distribution
2010/1/21
Using small-angle X-ray scattering (SAXS), we have studied the initial stage (nucleation and oligomerization) of actin polymerization induced by raising temperature in a stepwise manner from 1°C to 30...
Lensless x-ray microscope focuses on biological samples
x-ray microscope biological samples
2007/2/2
26 January 2007，Lenses for x-rays are notoriously tricky to manufacture because they rely on nanometre-scale features. For this reason, physicists developing x-ray microscopes have been keen to adopt ...
16 November 2006，Many biological cells are too small to be studied with an optical microscope and higher-resolution techniques such as x-ray diffraction and electron microscopy cannot be readily adapt...
