Proserin 413 is a medium for the serum-free cultivation of lymphocytes from whole blood.
Proserin 413 has been developed for the cultivation of lymphocytes from whole blood. Normally blood cells die rather quickly in culture, only lymphocytes can be cultivated over multiple divisions in culture. To achieve a division of non-proliferating cells, the cells must be stimulated with certain mitogens. These mitogens are mostly herbal lectins (phytohemagglutinin, PHA).
