This product may be used in fluorescence microscopy, microplate, cuvette, and flow cytometry applications. It can also be used to detect the contents of a sample DNA by plotting a standard emission-tocontent curve.\u003cbr\u003e\nMolecular Weight:\u003cbr\u003e\n561.93\u003cbr\u003e\nSpectral Properties:\u003cbr\u003e\nExcitation = 350 nm; Fluorescence = 461 nm.\u003cbr\u003e\nThe Hoechst stains are a family of fluorescent stains for labeling DNA in fluorescence microscopy. Because these fluorescent stains label DNA, they are also commonly used to visualize nuclei and mitochondria. Two of these closely related bis-benzimides are commonly used: Hoechst 33258 and Hoechst 33342. Both dyes are excited by ultraviolet light at around 350 nm, and both emit blue\/cyan fluorescence light with an emission maximum at 461 nm. The Hoechst stains may be used on live or fixed cells, and are often used as a substitute for another nucleic acid stain, DAPI. The key difference between them is that the additional ethyl group of Hoechst 33342 makes it more lipophilic, and thus more readily to cross intact cell membranes. In some applications, Hoechst 33258 is significantly less permeant than Hoechst 33342.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions--20°C, Appropriate long-term storage conditions--20°C, Storage information--20°C\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843544305833,"sku":"ab228551","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab228551","provider":"Iright","version":"1.0","type":"link"}
