Description

General description

CF^™568 is a red fluorescent dye with an excitation spectrum optimally matching the 568 nm line of the Ar-Kr mixed-gas laser. Antibody conjugates of CF^™568 are much brighter than those of Alexa Fluor^™ 568. In addition, the photostability of CF^™568 is superior to that of Alexa Fluor^™ 568, making CF^™568 a much better choice for demanding applications such as confocal microscopy and single molecule 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 much brighter antibody conjugates than Alexa Fluor^™568. 2. Extremely photostable. 3. Highly water-soluble.

Preparation Note

Protect from light

Reconstitution

Dissolve in water
