    TagYFP

Yellow fluorescent protein TagYFP

- Bright yellow fluorescence
- Monomeric protein with successful performance in fusions
- Fast maturation, high pH-stability and photostability
- Proven suitability to generate stably transfected cell lines
- Recommended for protein labeling

Performance and use

TagYFP can be easily expressed and detected in a wide range of organisms. Mammalian cells transiently transfected with TagYFP expression vectors produce bright fluorescence in 10-12 hrs after transfection. No cytotoxic effects or visible protein aggregation are observed.

TagYFP use for labeling of cells and cellular orgenelles.

TagYFP performance in fusions has been demonstrated in human cytoplasmic β-actin and α-tubulin models. An expected pattern of fluorescence has been obtained in each case.
