Flubi-2 is a fluorescein-biotin based pH-ratio dye (Ex=480 nm, Em= 520-560 nm) with a pK value of 6.7. Flubi-2 is a hydrolysis product of Flubida-2 (non-fluorescent, membrane permeable). Flubi-2 can be used for pH determination of organelles of the secretory pathway (such as golgi apparatus and endoplasmic reticulum) in living cells[1][2].
