DsRed-Monomer is an ideal fusion tag because it is a true monomer. The DsRed-Monomer fluorescent protein has been expressed as a fusion with a large panel of diverse proteins with diverse functions and subcellular locations. All the proteins localized properly, including actin and Golgi fusions, which have not performed well with tetrameric DsRed proteins.
The DsRed-Monomer sequence contains 45 amino acid substitutions, but maintains a spectral profile virtually identical to other DsRed fluorescent proteins. The DsRed-Monomer fluorescent protein is extremely stable, allowing you to monitor fluorescence over extended periods of time.
A Monomeric Red Fluorescent Protein
The monomeric nature of the DsRed-Monomer fluorescent protein (28 kDa) has been confirmed by FPLC gel filtration chromatography and pseudonative gel electrophoresis. Please see the Images & Data tab below for more information about these experiments.
The only anti-DsRed Antibody that detects DsRed-Monomer fluorescent protein is the DsRed Polyclonal Antibody. Visit the anti-DsRed Antibody page.
Recombinant DsRed-Monomer fluorescent protein is also available.
