The inset cup (4) is thus compressed elastically so that the blood bag (6) is compressed and the blood components centrifuged in the blood bag are transferred corresponding to the volume increase of the pressure pad (9) into an empty satellite-blood bag arranged in the adjacent chamber (2...
A further improvement to the blood processing centrifuge, in accordance with the invention, relates to the production of medicinally valuable blood platelet plasma from the concentrate product, which is designated Buffy Coat at blood donor centres. Before the Buffy Coat can be centrifuged, making the...
Whole vertebrate blood is a colloidal suspension of predominantly red blood cells (erythrocytes) in plasma. Whole blood also consists primarily of protein by dry weight, with only small amounts of lipid, carbohydrate and trace elements [19]. However, hematological parameters also vary among vertebrat...
The collection procedure can be useful for harvesting granulocytes and, in general, any sparse stratified component of a centrifuged solution where the sparse component is layered between more dense and less dense strata. 展开 DOI: US5704889 A ...
aIn order to eliminate in vitro artifacts, blood should be centrifuged within 3 hours of collection to isolate the serum or plasma (210). Serum and plasma may be kept at refriger-ated temperatures for up to 24 hours without loss of PSA. If analysis is delayed longer, then it is vital ...
Tubes were stored briefly on wet ice and then centrifuged for 20 min at 3,000 × g. Plasma was collected and frozen at −20°C until analyses. Lactate dehydrogenase activity, lactate concentration, and BHBA concentration were measured in milk serum and blood plasma using the test kits LDH ...
2.3. Separation of blood components and free AGE measurement in blood samples The amount of AGEs in blood samples was measured by the precise protocol described in our previous papers [9,10]. Serum was added to same amount of 6% sulfosalicylic acid, mixed, and centrifuged 13,000 rpm × 5 ...

The blood samples were centrifuged, and serum was removed and stored at −70 °C until the assay could be performed. Absolute creatine kinase-MB levels were determined by radioimmunoassay (Dade Behring Inc., Miami, FL, USA). Cardiac-specific troponin-I levels were measured by a paramagnetic ...
A method for increasing the quantitation of microorganisms in cell-containing or cell-free blood samples, included those intended for blood product transfusion purposes, is provided which employs a sustained level of sodium polyanethol sulfonate throughout microbial replication on solid media. In another...
