bisBenzimide H 33342 trihydrochloride can be used to study biochemicals and reagents, fluorescent probes, labels, particles and stains, luminescent compounds and detection and wavelength index. bisBenzimide H 33342 trihydrochloride, Hoechst 33342, has been used in a study to investigate the effects of inorganic and organic arsenic compounds on human T-lymphoblastoid leukemia cells. Hoechst 33342 has also been used in a study to examine the effects of 9 calcium antagonists on ABCG2/BCRP-mediated resistance and transport in HeLa and SN-38-resistant HeLa (HeLa/SN100) cells, overexpressing ABCG2/BCRP.

Biochem/physiol Actions

Membrane-permeable, fluorescent DNA stains with low cytotoxicity that intercalate in A-T regions of DNA.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Suitable for vital DNA staining of a variety of cell types; As a probe of membrane permeability in mammalian cells
