The centrifuge must be properly balanced. Following centrifugation, it is important to immediately transfer the liquid component (plasma) into a clean polypropylene tube using a Pasteur pipette.Serum and plasma tubes. The Plasma is the watery or liquid fluid portion of the blood, in which several blood cells are diluted and is obtained after the centrifugation by adding the anti-coagulating agents.The fluid or undiluted part of the blood, obtained after the complete coagulation of the blood, without adding an anticoagulating agent is called serum. Qualified personnel should draw a 6 ml red top tube of blood from a participant, with a label designating date and time of collection. Make sure that all tubes are legibly labeled, using a permanent marker/pen. After centrifuging, the clot is at the bottom of the tube, and the serum is on top of the clot). 7 days at 15-25C. If the serum is not analyzed immediately, the serum should be apportioned into 0.5 ml aliquots, stored, and transported at -20C or lower. Remains dark, myoglobin is confirmed clots, or within one hour of collection [ 5 ] [ Fragment size profile of cfDNA extracted from gel-serum tubes after 24 hours of incubation of serum clotting. The resulting components are: erythrocytes (red blood cells) at the bottom of the centrifuge tube. This clotted blood is then centrifuged, yielding serum, which contains two types of protein: albumin and globulin. Plastic tubes contain a contact activator to trigger clotting and come with (depicted) or without silicon gel.

If specimen is centrifuged before clotting is complete, a fibrin clot will form on top of the cell. excessive shaking during centrifugation. Next, the test tube is spun in a centrifuge and the blood clot is removed. Red-top tubes may required up to 60 minutes, while serum separator tubes (SST) may require up to 30 minutes. The first to be discussed is the time period between collection and centrifugation. We let the. Serum is usually collected in mottled red/gray, gold, or cherry red-top tubes, and red-top tubes are occasionally used. Immediately after centrifugation, pipette separated red-top serum or green-top/lavender-top plasma into a transport tube and label accordingly (serum, heparin plasma, EDTA plasma). After centrifugation, store the serum in a separate test tube and retain the red blood cells in the original tube.
