a.k.a. monomeric Blue light-excited RFP

mBeRFP is a basic (constitutively fluorescent) long stokes shift fluorescent protein published in 2013, derived from Entacmaea quadricolor. It is reported to be a somewhat slowly-maturing monomer with moderate acid sensitivity.

mBeRFP Sequence

mBeRFP was derived from mKate with the following mutations: S2_S2delinsVSKGE/V93S/S158D/D159Y/L174A/Y210S



at the same laser power, the fluorescence intensity of the LSS-mKate2 was not as high as that of mBeRFP
