Preparation of a diagnostic antigen of human melanoma based on lymphocyte activation as measured by intracellular fluorescein fluorescence polarization.
The intracellular fluorescein fluorescence polarization (IFFP) test indicates that peripheral blood lymphocytes (PBL) of cancer patients display stimulatory sensitivity to a short incubation with specific tumor protein extracts. In this work, a human lymphocyte activation melanoma antigen (LAMA) was purified from supernatant of a human melanoma cell line… (More)
