Looking for EGFP vectors? Upgrade to AcGFP1 or ZsGreen1 vectors
AcGFP1 has 94% homology to EGFP at the amino acid level.
- AcGFP1 and EGFP have similar excitation and emission maxima.
- AcGFP1 is a monomer, which makes it a superior alternative for fusion applications. EGFP has been reported to form dimers (Jain et al. 2001; Chen et al. 2002).
Another alternative to EGFP is ZsGreen1, a very bright, tetrameric green fluorescent protein that is ideal for reporter studies. ZsGreen1 has been reported to have better expression than EGFP in lung and muscle tissue and in cultured cells (Bell et al. 2007).
