WebIn contrast to the highly water soluble fluorophores Alexa Fluor 488 dye and fluorescein (FITC), Invitrogen BODIPY dyes have unique hydrophobic properties ideal for staining lipids, membranes, and other lipophilic compounds. ... Alexa Fluor 488 dye is a bright, green-fluorescent dye with excitation and emission wavelengths similar to those of ... WebFITC is conjugated randomly to hydroxyl groups of dextran at a frequency of 0.003 to 0.02 moles of FITC per mole of glucose. Fluorescent Properties. The excitation maximum of FITC-dextran is 490 nm. The emission maximum is 520 nm. 11 The fluorescence increases with pH and is optimal at pH 8 and above. 11. Method of Preparation
Which Excitation Should I Use for My Fluorophore? - NIGHTSEA
WebThus, excitation of fluorescein using a 488 nm laser will also produce excitation of rhodamine, although to a lesser degree. Furthermore, fluorescein emission will be detected in the photomultiplier channel or widefield filter set reserved for rhodamine. ... Generally, autofluorescence is greater for shorter excitation wavelengths, such as ... Web1. Introduction. In recent years, multiphoton microscopy (MPM) has made great progress in imaging biological tissues, especially brain tissue, due to its advantages of … irobot charging error 2
