Invitrogen™ Alexa Fluor™ 568 Antibody Labeling Kit

Invitrogen™ Alexa Fluor™ 568 Antibody Labeling Kit

Molecular Probes® Alexa Fluor® Antibody Labeling Kits provide a convenient means to label small amounts of antibodies with Alexa Fluor® dyes (choice of 10 colors). This kit is optimized for labeling 100 µg of antibody per reaction with orange-red fluorescent Alexa Fluor® 568. Comparably small amounts of other proteins (>40 kDa) can also be labeled.

The kit contains everything you need to perform five separate labeling reactions as well as to purify the resulting conjugates. Conjugates are ideal for multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, indirect FISH, and more. 

Features

• With an excitation and emission maximum of 577/603 nm, Alexa Fluor® 568 can be efficiently excited using a 568 nm Kr laser line and detected under standard Rhodamine Red/Cy3.5® filters
• Labeled proteins typically ready to use typically in 90 min (∼15 min hands-on time)
• Useful for labeling 100 µg of protein
• Optimized for small-scale labeling of any protein >40 kDa
• Purified using convenient spin filters
• Stabilizing proteins must be removed from the sample before labeling
• Includes detailed instructions for determining degree of labeling (DOL) 

Contents

• Alexa Fluor™ 568 Antibody Labeling Kit comes with 5 vials of reactive dye, sodium bicarbonate, purification resin, spin columns and collections tubes.
