Abstract:
Tetragonal hen egg white lysozyme is grown by the batch method in solution and gel media to study the influence of high magnetic fields on the quality of macromolecular crystals. The crystallographic quality of crystals grown in the absence and in the presence of 7- and 10-T fields are analyzed in terms of mosaicity and high-resolution X-ray imaging methods. Crystals grown by the batch method from solution showed a remarkable enhancement of the crystallographic quality, although the overall crystal quality was higher for gel-grown crystals than solution-grown crystals. The observed improvement in crystal quality can be attributed to the suppression of convective transport during the crystal growth process and the control of the nucleation kinetics by the use of a magnetic force.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
