CF405M

CF®405M (Ex-Max 408 nm/Em-Max 452 nm)

CF®405M from Biotium is a fluorophore with an excitation peak at 408 nm and an emission peak at 452 nm. It is spectrally similar to Pacific Blue, V450 and DY-415. It can be use in fluorescence microscopy and flow cytometry. Specifically, it has been validated for use in STED, Structured Illumination (SIM) and 2-Photon microscopy. In flow cytometry, superior alternatives are Brilliant™ Violet 480, Brilliant™ Violet 510 and StarBright Violet 515.
