GRADE & PURITYBioReagent?BioReagent grade — tested suitable for life-science and molecular-biology use. Use for cell culture, assays, and biochemical work needing biological compatibility.Biological Stain?Biological stain grade — dyes characterized for staining cells and tissues. Use in histology and microscopy where staining consistency matters.for Fluorescence analysis?Fluorescence-analysis grade — very low fluorescent impurities for clean spectra. Use in fluorescence assays where background interferes.for Microscopy?Microscopy grade — reagents/stains suited to sample prep and imaging. Use in microscopy where clarity and low background are needed.

Overview
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.
