OFPSpark® is a red (orange) fluorescent protein (excitation/emission maxima are 549 and 566 nm, respectively) derived from DsRed. Possessing high photostability and pH stability, OFPSpark® is more than twice brighter than mOrange2. Fast OFPSpark® maturation makes it clearly detectable in mammalian cells as early as within 8 hrs after transfection.
OFPSpark® can be expressed and detected in a wide range of organisms. Mammalian cells transiently transfected with OFPSpark® expression vectors produce bright fluorescence in 8 hrs after transfection. No cytotoxic effects or visible protein aggregation are observed. For its monomer structure, OFPSpark® performs well in some fusions and protein labeling applications.
