Goat polyclonal antibody to mCherry (Cherry fluorescent protein). mCherry protein is derived from DsRed, an engineered red fluorescent protein from so-called disc corals of the genus Discosoma. mCherry is a ~27 kDa protein that is optimally excited at a 587 nm and has a maximum of emission at 610 nm. It is a basic (constitutively fluorescent) red fluorescent protein and It is reported to be a very rapidly-maturing monomer with low acid sensitivity.
