Transportation: at room temperature for up to 3 weeks. Avoid prolonged exposure to light. Desiccate. Excitation Maximum (nm): 503 Emission Maximum (nm): 509Thiol reactive BDP FL maleimide is a reactive dye for protein labeling, which has identical structure with BODIPY® FL maleimide.BDP FL is a borondipyrromethene dye which has absorption and fluorescence spectra similar to fluorescein (FAM). However, this dye exhibits very high photostability. It is non-charged, and has low molecular weight. Its brightness is similar to fluorescein, R110 and xanthene dye derivatives like Alexa Fluor® 488. This fluorophore is ideal for fluorescent microscopy and many other applications. The fluorophore can substitute fluorescein for almost any application, and it is compatible with any FAM-capable fluorescent instrumentation.
