[An immunochemical study of M-HeLa cells as producers of human placental alkaline phosphatase].
While analyzing M-HeLa cells by IFA technique secretory and membrane-bound forms of human placental alkaline phosphatase (HPAP) were detected. Activity of secretory HPAP increased if cell density and incubation time were increased too. After short influence of heat shock (15 min at 42 degrees C) activity of secretory HPAP increased for 45% and intracellular HPAP 3 for 37%. It is proposed that HPAP take part in organization of first response to heat shock and support cellular thermotolerance.
