Description

General description

CF^™594 is a deep red fluorescent dye spectrally similar to Alexa Fluor^™ 594 and Texas Red^® dye. When conjugated to proteins, CF^™594 is significantly brighter than Alexa Fluor^™ 594 due to its high quantum yield and exceptional water solubility. CF^™594 also has excellent photostability, making it ideal for demanding applications such as confocal microscopy and single molecule imaging. These properties make CF^™594 the best deep-red dye for labeling proteins and nucleic acids. The dye is particularly useful in combination with our blue fluorescent CF^™350, green fluorescent CF^™488A and far red CF^™647 for multi-color imaging.

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.

Features and Benefits

1. Yields the brightest antibody conjugates among spectrally similar dyes. 2. Extremely photostable. 3. Highly water-soluble.
