The separation of tumor-infiltrating lymphocytes (TIL) from tumor mass of B16 melanoma was achieved by discontinuous density gradients centrifugation and the in vitro culture of TIL were investigated.
After sampling, the separation between coal ash and water is implemented by the measures of rapid centrifugation and vacuum filtration, in order to prepare the specimen for testing.
