Abstract:
Crystals of the self-complementary oligonucleotide d(CCAGGCCTGG) [Heinemann & Alings (1989), J. Mol. Biol. 210, 369-381] complexed with the hydroperoxide of cobalt-pepleomycin (CoPEP) were obtained by the hanging-drop vapour-diffusion method at 298 K. An X-ray diffraction data set was collected to 2.8 A at 100 K. The crystal belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 34.52, b = 59.88, c = 72.93 A.

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...
