high-speed centrifugationlipaselipid interferenceThe article discusses the accuracy of lipase activity results that was obtained with routine laboratory procedure with declared lipemia interference in lipemic samples. It states that the serum lipase activity was measured in native lipemic samples in two ...
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...
The force generated by the spinning rotor is described as the relative centrifugal force (RCF), also called the g force, and is proportional to the square of the rotor speed and the radial distance (the distance of the molecule being separated from the axis of rotation). 展开 ...
6.2 for the minimum speed needed to separate the particles of interest, then compare the column labeled gmin in Table 6.2 to identify the zonal rotors which may be competent for the task. The next consideration is Volume: B-XIV and B-XV types may both be suitable for the separation of a...
(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 range so as to obtain the first predefined centrifugal force range and during a first period of time to perform separation into phases of a fluid provided within the containers,rotating the centrifuge platform at a second centrifugal speed range so as to reach the second predefined ...
Ultracentrifugation of solubilizedbiological membranes(at 100,000g,for 15–60 min) is an essential first step in anypurificationprotocol. Among other things, it removes insoluble components that would impede further purification steps. However, separation ofindividualmembrane proteinsusually is pe...
Centrifugation separates particles within the specimen according to their shape, dimensions, and density and basically can be defined as a separation method. The centrifuge is an essential device in medical laboratories to prepare the serum, plasma, and urine samples for analysis. It is basically an...
After removal of cells and cell debris, a speed of 110,000×g or 40,000×g was used for the ultracentrifugation or centrifugation enrichment process, respectively. The enriched exosomes were analyzed using the BCA assay, 1-D gel separation, transmission electron microscopy, Western blotting, and...
The compressive strain–stress curve of a scaffold was measured at room temperature with a 50 N load cell and at a cross-head speed of 0.5 mm/min on a Hounsfield testing machine (Model: H10 K/M527). The compressive Young's modulus (kPa) was calculated by taking the slope at the ...
