| 1. | Purification before culturing can be accomplished by CsCl density gradient centrifugation.
|
| 2. | Optionally, the final lysate is subjected to further purification by CsCl density gradient.
|
| 3. | Linderstorm-Lang, in 1937, discovered that density gradient tubes could be used for density measurements.
|
| 4. | :The extent of a density gradient is almost immeasurable even under conditions favoring it.
|
| 5. | The tube contains an insert that prevents the mixing of the density gradient medium and blood.
|
| 6. | :: : : There's no surface tension because there's no surface, just a gradual density gradient.
|
| 7. | The last term includes temperature and density gradients of the background distribution function, which drive the perturbation.
|
| 8. | Isopycnic centrifugation refers to a method wherein a density gradient is either pre-formed or forms during high speed centrifugation.
|
| 9. | Heavy liquids are often used for determination of density in mineralogy, for density gradient centrifugation and for separating mixtures.
|
| 10. | Surface heat and freshwater fluxes create global density gradients that drive the thermohaline circulation part of large-scale ocean circulation.
