Excerpts

[Dimer1 is an intermediate DsRed mutant in the development dimer2 and mRFP1]. Dimer1 was somewhat better than wild-type DsRed both in terms of brightness and rate of maturation but had a substantial green peak equivalent to that of DsRed.T1. Dimer1 was also somewhat blue-shifted with an excitation maximum at 551 nm and an emission maximum at 579 nm.
