Specimen collection method:
1. Serum:
After the blood coagulates naturally at room temperature for 10-20 minutes, centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. If a precipitate forms during storage, it should be centrifuged again.
2. Plasma:
EDTA, sodium citrate or heparin should be selected as the anticoagulant according to the requirements of the specimen, mixed for 10-20 minutes, and centrifuged for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. If a precipitate forms during storage, it should be centrifuged again.
3. Urine:
Collect with sterile tubes. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. If a precipitate forms during storage, it should be centrifuged again. Pleural and ascites, cerebrospinal fluid refer to this practice.
4. Cell culture supernatant:
When detecting secreted components, collect them with sterile tubes. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully.
5. Cultivation of cells When testing the contents of cells, dilute the cell suspension with PBS (PH7.2-7.4) to a cell concentration of about 1 million / ml. By repeatedly freezing and thawing or adding tissue protein extraction reagents, the cells are destroyed and the intracellular components are released. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. If a precipitate forms during storage, it should be centrifuged again.
6. Organize the specimen After cutting the specimen, weigh it. Add a certain amount of PBS, PH7.4. Quickly freeze and save with liquid nitrogen for later use. After the specimen melts, it still maintains a temperature of 2-8 ° C. Add a certain amount of PBS (PH7.4), or tissue protein extraction reagent, and homogenize the specimen by hand or homogenizer. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. After aliquoting, a portion is to be tested, and the rest is frozen for future use.
