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

Important Features of Microscale Protein Labeling Kits:
  • Labeled proteins typically ready to use typically in 2 hours (~30 minutes hands-on time)
  • Optimized for 20–100µg 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

    Stable Reaction Chemistry and Superior Alexa Fluor™ Dyes
    In the Microscale Protein Labeling Kits, the reactive dye contains a succinimidyl (NHS) ester moiety that reacts with primary amines of proteins to form stable dye-protein conjugates. Compared to traditional dyes, Alexa Fluor™ dyes are brighter, more photostable, and more pH resistant between pH 4 and 10. And generally when using Alexa Fluor™ dyes, higher degrees of labeling can be achieved without intramolecular quenching. For details see Alexa Fluor™ Dyes Spanning the Visible and Infrared Spectrum—Section 1.3.
