[Functional characteristic of TTK-lymphocytes in vitro, cytotoxicity and mixed lymphocyte culture (MLC)]. / Funktionelle Eigenschaften von TTK-Lymphozyten in vitro, zytotoxizität und Lymphozytenmischkultur (MLC).

A simple method of cryopreservation (TTK) of lymphocytes is presented. The functional properties of TTK-lymphocytes are examined by the lymphocyte toxicity micro test and in the mixed lymphocyte culture (MLC). 51Cr-release technique is performed as a measure for reversible and irreversible cell damages in the course of the Cryopreservation process.
