mWasabi is a monomeric green fluorescent protein derived from mTFP1. mWasabi is significantly brighter than all other currently available monomeric green fluorescent proteins. It is approximately 2-fold brighter than EGFP and has a similar pH sensitivity and photostability. Unlike many commonly used fluorescent proteins, mWasabi is a true monomer and is most likely to not interfere with function or localization of its fusion partner. Licensing opportunities
