Monomeric (m)Eos2 is an engineered photoactivatable fluorescent protein widely used for superresolution microscopy. An optical highlighter isolated from another stony coral (Lobophyllia hemprichii), the tetrameric EosFP (named after the goddess of dawn in Greek mythology), behaves similarly to Kaede and the other variants described above. EosFP emits bright green fluorescence at 516 nanometers, and can be photoconverted to orange-red (581 nanometers) fluorescence when illuminated at near-ultraviolet wavelengths. Random and site-directed mutagenesis of tetrameric EosFP was used to generate two dimers and a true monomeric protein named mEosFP.

This antibody binds specifically to mEos2 GFP.

Store at 4°C if intended for use within one month, otherwise, store at -20°C to -80°C. The lyophilized antibody is stable for at least 18 months after the date of receipt when stored at -20°C to -80°C. After reconstitution, it can also be aliquoted and stored frozen at -20°C to -80°C in a manual defrost freezer for at least 6 months without detectable loss of activity. Upon reconstitution, the antibody can also be stored for 30 days at 4°C. Please avoid freeze-thaw cycles, as this will lower the activity of the antibody.
