General description

Cell-permeable adenine-thymidine specific fluorescent stain. Useful for staining DNA, chromosomes or nuclei for fluorescence microscopy and flow cytometry applications. DNA-bound dye has an excitation maximum of 358 nm and an emission maximum of 460 nm. Useful for the simultaneous study of the cell cycle and apoptosis in unfixed cells. Induces cell differentiation. H33342 and the related compound H33258 (Cat. No. 382061) have been used in conjunction with RNA aptamers in the 5′ untranslated region (UTR) to control expression of transfected gene constructs. Exhibits a 10 fold greater cell-permeability than H 33258.
