process and apparatus for separating serum contained in a volume of blood by centrifugation, the amount of blood is introduced into a tube (1) in which a body of separation (5, 5 ') is also present, after which the test tube (1) is centrifuged.the blood is separated into a heavy ...
The separation of biomarkers from blood is straightforward in most molecular biology laboratories. However, separation in resource-limited settings, allowing for the successful removal of biomarkers for diagnostic applications, is not always possible. Th
A new device for aspirating serum from blood collection tubes following centrifugation is described and details of its design and construction are presente... WR Seebaugh,CA Bradley,FF Parl - 《IEEE Transactions on Biomedical Engineering》 被引量: 1发表: 2007年 Isolation and identification in human...
Collection/Processing MethodBlood is collected via cardiac puncture into sterile bags. Blood is separated by cup centrifugation and double spun. Serum is subsequently passed through a series of filters terminating with triple 0.1 µm pore size filters. Product is dispensed in IS0 14644 Class 5 La...
1.Coated with ultrasonically spray-dried microscopic silica particles which activate blood clotting. 2.Contain an inert polymer gel that separates the serum from the blood clot during centrifugation, preventing contamination of the serum. 3.Gently mix the blood collection tube by inverting 5-6 t...
Following centrifugation, POSM was determined via the single-sample osmometer. 3 mL of blood were removed from the serum separation vacutainer and placed into a serum transfer tube. This was done to ensure the same amount of blood was used to determine SV for each sample, as no formula ...
METHOD AND DEVICE FOR SEPARATING SERUM/PLASMA FROM BLOOD Method and device for separating the serum included in a certain volume of blood by way of centrifugation, said volume of blood being introduced into a test tube (1) in which a so-called separating body (5; 5') is also present, af...
A gel and heparin Tube is a kind of anti-coagulation tube with an inert separation gel at the bottom of the heparin tube (Lithium Heparin or Sodium Heparin). Through centrifugation, the separation gel can form a barrier between plasma and blood cells and ...
After centrifugation on the machine, the hydrogen bond between the separating gel molecules is broken and converted into a low viscosity fluid, and the precise specific gravity is between serum and blood clot, which can separate the two well. When the external centrifugal force disappe...
General patient exclusion criteria: patients with blood viral infection and different kind of tumors. For EVs separation, sera were thawed, transferred in clean tubes and diluted in PBS to reach equal volume of 1.4 ml. They were centrifuged 5 minutes at 1200 rpm, the supernatants ...
