A method for the separation of blood into the components thereof, characterized by subjecting the blood to strong centrifugation thereby separating said blood into an upper layer (A) of platelet-deficient blood plasma an intermediate layer (B) of a mixture of platelets and white blood corpuscles...
TRA proposes Phase II development of several novel devices to separate blood cells from plasma. These devices use inclined surface and ultrasonic enhancement of centrifugation to speed sedimentation of the cells with smaller centrifugal forces. Because TRA can produce equivalent sedimentation with lower ac...
For a recent review on modern centrifugation techniques see [229]. Centrifuges can be categorised by their running speed: clinical centrifuges allow velocities of a few thousand rounds per minute, high speed centrifuges up to 25000rpm. Centrifuges which allow even higher speeds are called ultra...
Differential centrifugation is a method used to separate different types of extracellular vesicles (EVs) from a sample by gradually increasing the speed of centrifugation to isolate smaller particles. This technique is commonly used for EV isolation and is suitable for various sample volumes. ...
But the pelleted materials thus obtained are usually contaminated with many different components of the cell; in the case of Dounce homogenates, for example, the low-speed nuclear fraction contains not only unbroken cells but also large sheets of plasma membrane wrapped around the nuclei; ...
1.METHODS:Bacteria from CSF were enriched by centrifugation with high speed.方法:采用高速离心法浓集脑脊液中的细菌。 2.Methods The kidneys of young SD rat were processed to separate and purify the renal tubule cells by Percoll gradient centrifugation.方法选用SD幼鼠的肾组织进行细胞培养,采用Per-coll...

“buffy coat”. And at lower centrifugation speed, blood may be separated into two layers, RBC and platelets rich plasma (PRP). By constant rotation of the centrifuge, a sharp distinct edge can be maintained at the boundary of the separated layers, e.g. the separated RBC layer and PRP ...
(not shown in the Figure) which allows for adjustment of the speed of descent or ascent of the travelling plate according to the requirement of the operation. The operation of the pressomat is very simple: Upon pressing the start button, the travelling plate begins its downward movement and ...
speed (100,000 × g). Among the sEVs, four subcategories can be defined. (iiia) sEVs coenriched in CD63, CD9, and CD81 and endosome markers (i.e., bona fide exosomes); (iiib) sEVs devoid of CD63 and CD81 but enriched in CD9 (associated with plasma membraneand ...
