Invitrogen™ Alexa Fluor™ 555 Microscale Protein Labeling Kit

Invitrogen™ Alexa Fluor™ 555 Microscale Protein Labeling Kit

Microscale Protein Labeling Kits provide a convenient means for attaching a fluorescent label to a small amount of antibody or protein (20–100 µg). The kits are available in four Alexa Fluor® colors (or biotin) and supply everything needed for three labeling and separation reactions.

Features

• Labeled proteins typically ready to use typically in 2 hours (∼30 minutes hands-on time)
• Optimized for 20–100 µg of protein with molecular weights between 12 and 150 kDa
• Purified using convenient spin filters with yields between 60 and 90%
• Stabilizing proteins must be removed from the sample before labeling
