Depositor Comments

We received EKAREV FRET biosensor from Matsuda-lab (Japan). We subsequently improved by insertion of a Turquoise2 synthetic DNA, including 169 silent mutations (reducing recombination) and adapted the sensor domain by point mutagenesis. The generation of stable cell lines using this plasmid requires the co-transfection of a transposase-expressing plasmid. The depositing lab recommends the use of Plasmid 158774.
