  • Scientific Background mCherry is an engineered derivative of one of a family of proteins originally isolated from Cnidarians (jelly fish, sea anemones and corals). The mCherry protein was derived from DsRed, a red fluorescent protein from so-called disc corals of the genus Discosoma. DsRed is a 223 amino acid ~28 kDa protein similar in size and properties to GFP, but, obviously, produces a red rather than a green fluorochrome. The original DsRed was engineered extensively in the Tsien lab to prevent it from forming tetramers and dimers and to modify and improve the spectral properties (1-3). The resulting monomeric protein is useful for applications such as Foerster Resonance Energy Transfer (FRET, also known as Fluorescence Resonance Energy Transfer). Several further cycles of mutation, directed modification and evolutionary selection produced mCherry, which is monomeric and has an excitation maximum at 587 nm and and emission maximum at 610 nm (4).

    Images, Protocols & SDS

  • A: Western blot analysis of HEK293 cells transfected with pFin-EF1-mCherry vector. R-1654-100 reveals a strong protein band in transfected cells (Lane 1). Non-transfected control cells (Lane 2) show no mCherry protein band.
    B: Immunofluorescence analysis of mCherry-transfected HEK293 cells with R-1654-100. Specificity of R-1654-100 for mCherry is shown by superimposing mCherry fluorescence (red) with R-1654-100 antibody staining (green), which results in a yellow color. mCherry staining is also seen in the nucleus, which might be due to degradation of mCherry molecules, causing the release of the low molecular weight mCherry fluorochrome.

  • Western blot analysis of HEK293 cell lysates, and recombinant protein solutions using rabbit antibody to mCherry (green, 1:1,000). [1] protein standard, [2] HEK293, [3] HEK293 cells transfected with mCherry-HA construct, [4] mCherry recombinant protein, [5] GFP recombinant protein, and [6] HEK293 transfected with a full length GFP construct. A major band at about 28 kDa corresponds to mCherry protein. The antibody does not cross-react with GFP protein. The same blot was simultaneously probed with a chicken antibody to HSP60 (red, lanes 2-6).
