eBFP2

This is an enhanced blue fluorescent protein with an excitation maximum of 363nm and an emission maximum of 448nm.[1] Engineered in Ai et al. 2007 through "rounds of random mutagenesis and screening."[2] Ai et al. 2007 describes eBFP2 as "a variant that is 4-fold brighter and 550-fold more photostable than EBFP."[2].

The paper does warn that eBFP2 "may retain wild-type GFP’s tendency to dimerize at high concentrations. However, it has been suggested that the A206V “superfolder” mutation of EBFP2 could hinder dimerization."[2]
