Observations on interactions between fluorescein-iso-thiocyanate conjugates and cells in vitro

RESUMO

During the course of some routine immunofluorescence studies `non-specific' staining occurred in the absence of free fluorescein and of any known impurities. The cause of such staining seems to be associated with phasic changes occurring at varying population doublings (`passages') in species-homologous cells subjected to serial cultivation.
