Electra1 Sequence

Electra1 was derived from mRuby3 with the following mutations: K6E/M63L/Y64F/R67K/E114G/K138E/N143F/D151N/G167D/C172A/F174I/N186D/H197Y/I202V/Q213L
amino acid numbers relative to eqFP611. show relative to mRuby3

GenBank: OL631606


Quantification of intracellular brightness revealed that Electra1 and Electra2 were 2.3- and 2.1-fold brighter than mTagBFP2
