A new method for detecting mycoplasma in cell cultures using colocalization of DNA and membrane staining
Published 2025-09-01Get full textMycoplasma often surreptitiously contaminates cell cultures without detection, mainly parasitizing the cell surface and thus interfering to some extent with the cells. Direct DNA staining of cell cultures often yields equivocal results and will only reliably detect heavily contaminated cultures. Int...
