Scientific Data Images for mCherry Antibody

Immunocytochemistry/ Immunofluorescence: mCherry Antibody [NBP2-25158]

Immunocytochemistry/ Immunofluorescence: mCherry Antibody [NBP2-25158]

Immunocytochemistry/Immunofluorescence: mCherry Antibody [NBP2-25158] - HEK293 cells transfected with mCherry, stained with mCherry antibody and viewed in a confocal microscope. Most HEK293 cells are not transfected so only the nucleus of these cells can be visualized with a blue DNA stain. Cells which are transfected with mCherry are bright red, and staining with the mCherry antibody is shown in Green. The green antibody staining is only seen cells which express mCherry, and the superimposition of the green and red results in an orange signal. Interestingly stronger mCherry staining is seen in the nucleus, possibly due to degradation of some mCherry molecules releasing the low molecular weight mCherry fluorochrome.
Western Blot: mCherry Antibody [NBP2-25158]

Western Blot: mCherry Antibody [NBP2-25158]

Western Blot: mCherry Antibody [NBP2-25158] - Analysis of NBP2-25158. Lane 1. Lysate of HEK293 cells transfected with pFin-EF1-mCherry vector. There is a strong clean band at about 29kDa corresponding to mCherry (predicted molecular weight ~27kDa). Lane 2, lysate of untransfected HEK293 cells show no protein bands. The NBP2-25158 antibody was used at 1:2,000 dilution.

Western Blot: mCherry Antibody [NBP2-25158]

Western Blot: mCherry Antibody [NBP2-25158] - Analysis of HEK293 cell lysates, and recombinant protein solutions using chicken mCherry pAb, dilution 1:2000 (Green). [1] protein standard, [2] HEK293, [3] HEK293 cells transfected with an mCherry-HA constract, [4] pure recombinant mCherry protein (predicted molecular weight ~ 27kDa), [5] pure recombinant GFP protein and [6] HEK293 transfected with a GFP construct. The major band at about 30kDa corresponds to mCherry-HA protein and the slightly larger recombinant form runs at about 33kDa due to presence of a His tag and other vector derived sequence. The mCherry antibody reacts strongly with both mCherry constructs and does not react with GFP protein. The blot was simultaneously probed with mouse HSP60 mAb, dilution 1:10000 (Red), which reveals a band at 60kDa only in the cell lysates.

Background: mCherry

mCherry is a monomeric red fluorescent protein (mRFP) belonging to the mFruits family which is brighter and more photostable compared to the first-generation mRFP1, making them ideal for fluorescence microscopy (1). mCherry has an excitation maximum at 587 nm and an emission maximum at 610 nm. mCherry protein was derived from DsRed, a red fluorescent protein from the coral Discosoma (disc anemone) (2). The red chromophore of DsRed has a similar topology to GFP, the green fluorescent protein isolated from the jellyfish Aequorea Victoria, but has extended pi-electron conjugation resulting in red-shifted absorbance and emission (3). mCherry is 236 amino acids (aa) in length with a theoretical molecular weight of 28 kDa and has a crystal structure with the chromophore forming a central helix shielded within an eleven-stranded beta-barrel (3).

mCherry can be used as a long-wavelength hetero-FRET (fluorescence resonance energy transfer) acceptor and probe for homoFRET experiments given its high peak molar absorptivity, folding efficiency, and superior spectral properties (4). Additionally, because mCherry does not interfere with other plasmids or alter the growth of Legionella species during intracellular growth, it can be used for constitutive gene expression in a variety of gram-negative bacterial species (5). For example, a plasmid developed to constitutively express mCherry under the Ptac promoter has been used in several Legionella species including L. pneumophila, the causative agent of Legionnaires' disease (5).
