In western blot ~28 kDa band is detected corresponding to intact full-length mCherry on HEK293 cells transfected with mCherry vector.Sequence identity between mCherry and original GFP protein is 27%. Antibody does not cross with GFP or eGFP and likely not any of the relatives in western blot.
mCherry is derived from DsRed, a red fluorescent protein from the genus Discoid. DsRed is a 223-amino acid ~28kDa protein that is similar in size and properties to GFP, but it produces a red rather than a green fluorescent dye. The monomer form of mCherry is useful for applications such as Forster Resonance energy transfer (FRET, also known as fluorescence resonance energy transfer). The protein is an engineered derivative of one of the protein families originally isolated from cnidarians (jellyfish, anemones, and corals).
