DsRed-Express2 fluorescent protein has even higher solubility, and was designed for whole-cell and stem cell applications (2).
The DsRed-Express and DsRed-Express2 fluorescent proteins can be detected with the DsRed Monoclonal and Polyclonal Antibodies. They can be differentiated from mCherry using the mCherry Monoclonal Antibody, which recognizes mCherry but not DsRed-Express or DsRed-Express2. Visit the anti-DsRed-Express Antibody page.
Recombinant DsRed-Express fluorescent protein is also available.
