Isolation of ribosome microcrystals
Journal of Molecular Biology, 1970Abstract A method of isolating large quantities of crystallized ribosomes from hypothermic chick embryos is described. The isolated ribosome crystals maintain the same average dimensions and the same type of aggregations as those prepared in vivo .

Growing and making nano- and microcrystals
Nature Protocols, 2022Thanks to recent technological advances in X-ray and micro-electron diffraction and solid-state NMR, structural information can be obtained by using much smaller crystals. Thus, microcrystals have become a valuable commodity rather than a mere stepping stone toward obtaining macroscopic crystals.

Microcrystals of a Modified Fibrinogen
Nature, 1972Fibrinogen forms microcrystals after cleavage with an enzyme from Pseudomonas. Electron microscope images reveal a close relation between these structures and fibrin. The results support the view that no major intramolecular rearrangement occurs in the fibrinogen-fibrin conversion.

Supramolecular chirality in peptide microcrystals
Chemical Communications, 2015VCD reveals supramolecular chirality in microcrystals of two peptide segments from human islet amyloid (IAPP, amylin). Previously such supramolecular chirality has been observed by VCD only for amyloid fibrils.

Framboids are constituted by microcrystals with approximately log-normal size-frequency distributions, and 95% of framboidal microcrystals are between 0.1 and 3.1 μm. Nanocrystals are not generally observed in framboids. Packing efficiencies vary between close-packings in which the microcrystals occupy up to 74% of the framboid volume and random ...

Magnetically Responsive Calcium Carbonate Microcrystals
ACS Applied Materials & Interfaces, 2009Here we report the fabrication of magnetically responsive calcium carbonate microcrystals produced by coprecipitation of calcium carbonate in the presence of citrate-stabilized iron oxide nanoparticles. We demonstrate that the calcite microcrystals obtained possess superparamagnetic properties due to incorporated magnetite nanoparticles and can be ...

Fine structure of polysaccharide microcrystals
Planta, 1969Negative staining showed the presence of microcrystals in various polysaccharides. Cellulose microcrystals from Valoniopsis, Vaucheria, and an unidentified tunicate had widths of 20, 27, and 30 Å, respectively. Mannan microcrystals from Acetabularia were 10x25 Å and were oriented in linear arrays with their long axis perpendicular to the array axis ...

Luminescence polarization of CdSe microcrystals
Physical Review B, 1992We have considered theoretically the polarization of the luminescence of small CdSe microcrystals due to the hexagonal structure of the lattice. We derive the energy spectrum and wave functions of holes in spherical microcrystals. It is shown that the value of the splitting between the A and B hole states in microcrystals could be five times smaller ...

A Study Of Microcrystals Of Fibrinogen
Thrombosis and Haemostasis, 1981We are interested in the application of image analysis to the structural determination of fibrinogen. This analysis is performed on the electron microscope images obtained from microcrystals of slightly degraded fibrinogen. The proteolysis of fibrinogen is carried out using bacterial proteases fixed onto sepharose.
