Patent ID: 8420781

Claim:
An isolated DNA encoding a fluorescent protein described in the following (a) or (b): (a) a protein having the amino acid sequence shown in amino acids 34-255 of SEQ ID NO: 47, amino acids 34-255 of SEQ ID NO: 45, full-length SEQ ID NO: 41, or full-length SEQ ID NO: 43; or (b) a protein having the amino acid sequence shown in amino acids 34-255 of SEQ ID NO: 47, amino acids 34-255 of SEQ ID NO: 45, full-length SEQ ID NO: 41, or full-length SEQ ID NO: 43 except that one to 10 amino acids have been mutated by deletion, substitution, and/or addition, and which has fluorescence properties and a stokes shift of 100 nm or greater.
