WebChromomycin A 3 is an anthraquinone antibiotic and antitumor agent isolated from S. griseus that is used as a fluorescent probe for DNA with excitation/emission spectra of 445/575 nm. 1, 2 Its DNA binding is specific to two or more contiguous GC base pairs, which makes it suitable for characterizing heterochromatin in plants with species ... WebJan 29, 2024 · CMA3 is an anthraquinone glycosidic antibiotic, produced by Streptomyces griseus ( 21 ). The anti-cancer effects of CMA3 have been proposed since the 1960s ( 22, 23 ). Side effects of CMA3 in advanced breast cancers have interrupted that use ( 24) but it is widely used for DNA staining ( 25 ).
