22G Sequence



Deposited: ,


We prepared a cDNA library from Pectiniidae, a species of coral that emits faint fluorescence upon irradiation with ultraviolet light. Approximately 300,000 bacterial colonies containing individual cDNA clones were screened for fluorescence. A single clone (22G) encoding a greenish fluorescent protein with highest homology to mcavGFP (Labas et al 2002) (74.6%) was identified.
