Anwendung

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.

Many potentially therapeutic molecules have been identified for treating Duchenne muscular dystrophy. However, targeting those molecules only to sites of active pathology is an obstacle to their clinical use. Because dystrophic muscles become extensively inflamed, we tested whether expressing a therapeutic
