Anti-mCherry Antibody (1C51)
Our Anti-mCherry mouse monoclonal primary antibody detects mCherry, and is IgG. It is validated for use in ICC, WB.
Left: Detection of mCherry protein (red) in transfected HEK293 cells by Immunocytochemistry. The cells were stained with anti-mCherry antibody in the green channel. Transfected cells appear yellow, showing overlap of the transfected mCherry protein and the anti-mCherry antibody. Untransfected HEK293 cells do not express mCherry and do not stain with the antibody, but their nuclei can be visualized using a DNA stain (blue). Right: Western blot analysis of HEK293 cell lysates, and recombinant protein solutions using mouse antibody to mCherry (green, 1:1,000). [1] protein standard, [2] HEK293 control cells, [3] HEK293 cells transfected with mCherry-HA construct, [4] mCherry recombinant protein, [5] GFP recombinant protein, and [6] HEK293 transfected with GFP construct. The major band at about 30 kDa corresponds to mCherry protein. The antibody does not react with GFP protein. The same blot was simultaneously probed an antibody to HSP60 (red, lanes 2-6).

Product Details
mCherry
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).
