For enzymological methods, we should pay attention to the enzyme used. Centrifuge the digest at g for 5 min at room temperature, discard the supernatant. Enzyme digestion, mechanical dispersion and chemical dispersion can be applied to tumor tissue to obtain single cell suspension. Make sure that the cell samples are fresh, and sample preparation and detection should be finished as soon as possible. Add 2 mL 0. Wash the cells with cell staining buffer or PBS with 0.
After centrifugation, the blood in the tube should be clearly divided into marseillaiw layers. For example, if the tissues are rich in cells such as lymphosarcoma, optic neuroblastoma, brain tumor, undifferentiated tumor, medullary tumor, and some soft tissue sarcoma, the simple mechanical methods will be a recommended choice to obtain massive high-quality mono-dispersed cells. Collect peripheral blood with heparin anticoagulation.

Staining cells with fluorescence antibodies stain the cells. The remaining steps are the same as the grinding method. Sign up for newsletter today. Do not add too fast to prevent the blood from mixing with the separating solution.
A standard curve should be generated for each set of samples assayed. Remove the undigested lumps with mesh strainer.
The preparation of single cell suspension from paraffin-embedded tissue expands the scope of application for flow cytometry. Add 10mL PBS to rinse the grinder.
