CF^TM 647 hydrazide

NA.41

CF^™647 is a cyanine-based far-red fluorescent dye spectrally similar to Cy^®5 and Alexa Fluor^® 647. CF^™647 also has comparable brightness and photostability as Cy^®5 and Alexa Fluor^®647.

CF^™ dye hydrazides can be used as a fixable polar tracers for visualizing cell morphology,or for gap junction studies. The dyes can be introduced into cells by microinjection. For conjugation to aldehyde or ketone groups (such as carbohydrate molecules after peroxidation with periodate) we recommend using the more reactive CF aminooxy dye forms.

1. Has comparable brightness and photostability as Cy^®5 and Alexa Fluor^®647. 2. Highly water-soluble. 3. pH-insensitive.
