Description_x000D_ General description_x000D_ This product is prepared by labeling highly cross-adsorbed goat anti-mouse IgG (H+L) with the far-red fluorescent dye CF640R. The antibody has been adsorbed against Bovine, Chicken, Goat, Guinea Pig, Hamster, Horse, Human, Rabbit, Rat and Sheep serum to minimize cross-reactivity. CF640R is a novel rhodamine-based dye spectrally very similar to Cy5 and Alexa Fluor 647. CF640R is much brighter than Cy5 and at least as bright as Alexa Fluor 647 when excited at 633 or 635 nm. However, the most important advantage of CF640R is its exceptional photostability. CF640R is far more photostable than the cyanine-based dyes Cy5 and Alexa Fluor 647. It is also more photostable than Atto 647N, a dye that has been extensively used in single molecule-based imaging. CF640R is also extremely water-soluble and pH-insensitive. These properties make CF640R a much better alternative to Cy5, Alexa Fluor 647 and other spectrally similar dyes_x000D_ Specificity_x000D_ Binds all mouse IgGs (minimal cross-reaction with bovine, chicken, goat, guinea pig, syrian hamster, horse, human, rabbit, rat and sheep proteins)_x000D_ Immunogen_x000D_ mouse IgG(H+L)_x000D_ Physical form_x000D_ Supplied in phosphate buffered saline with 0.05% sodium azide, 50% glycerol and 0.2% BSA._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Legal Information_x000D_ This product is distributed by Sigma-Aldrich Co. under the authorization of Biotium, Inc.
