Thiol 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.
