mCherry is the second generation monomeric red fluorescent protein that have improved brightness and photostability. The recombinant mCherry is expressed and purified from transformed E. coli using a method that ensures high purity and maximal fluorescence intensity.
Catalog #M2690-20
The protein is a 28.8kD monomer with 256 amino acids, pI 6.23. Ex.= 587 nm (540-590 nm); Em.= 610 nm (550-650 nm). The protein is engineered with 6xHis-tag on the N-terminus, which can be used for detection with anti-His-Tag antibody or protein purification/removal by using Ni++ beads.
ApplicationsSuitable for use as standard/positive control for SDS-PAGE and for Western Blot analysis of mCherry-transfected cells. Suitable for use in labeling proteins or antibodies. Also suitable for use in calibration of fluorometers and flow cytometers, and fluorescence microscope. mCherry protein can be microinjected into cells and tissues and is also ideal for fuison tag applications. Can be used for triple labeling with EGFP, CFP, YFP and other dyes. The 6xHis-Tag on the N-terminal can be used in Western Blot detection with 6xHis-Tag antibodies. The 6xHis-Tag can also be used in removal or purification of the mCherry protein. Other applications not tested.
