The Heidelberg flow analyzer and sorter (HEIFAS) approach on the prescreening of uterine cancer
J Histochem Cytochem.

Abstract
A dual laser flow system has been proved and used with a novel staining method for simultaneous quantitative DNA and protein analysis. A diamidinophenylindole compound (DAPI) for DNA has been employed in combination with sulforhodamine (SR 101) for protein. With this dye mixture various cell types of the cervical smear could be identified. Despite some overlapping, clusters of leukocytes, endocervicals, (para)basals, intermediates, superficials and dys/neoplastic cells together with artificial events could be discriminated. Up to now the problem of negative cells which create positive signals (false alarms) in the dys/neoplastic region could not be sufficiently solved.
