متن کاملGeneralized Enrichment of Categories
We define the phrase ‘category enriched in an fc-multicategory’ and explore some examples. An fc-multicategory is a very general kind of 2-dimensional structure, special cases of which are double categories, bicategories, monoidal categories and ordinary multicategories. Enrichment in an fc-multicategory extends the (more or less well-known) theories of enrichment in a monoidal category, in a b...
متن کاملDensity Gradient Centrifugation in Angle-head Rotors.
Preparative isopycnic density-gradient centrifugation is ordinarily done in high-speed swinging-bucket rotors such as the Spinco SW 39 and SW 25. In addition to requiring this special equipment, the technique is severely limited by the small number of samples and the low total-sample volume which may be used. In recent studies on methods for isolating small numbers of virus particles from tissu...
متن کاملSeparation of Hela Cells by Colloidal Silica Density Gradient Centrifugation
Using a colloidal silica density gradient, HeLa cells in mitosis were found to have a density of 1.040-1.046 g/cc, lighter than the remaining interphase cells. The mitotic cells could be harvested and cultured after centrifugation, showing growth synchrony by measurement of a peak in mitotic index 21 hr after establishing the culture. By using Colcemid or vinblastine sulfate, HeLa cells were ar...
