Invitrogen™ Alexa Fluor™ 680 Protein Labeling Kit


The Alexa Fluor 680 Protein Labeling Kit provides the materials needed to conveniently label an antibody or protein with amine-reactive near-IR fluorescent Alexa Fluor 680 dye (ex/em 679/702 nm). This kit is optimized for labeling 1 mg of IgG antibody per reaction with Alexa Fluor 680. Comparably small amounts of other proteins (>20 kDa) can also be labeled. Each kit contains everything needed for three labeling reactions and subsequent purification for free dye removal. Our protein labeling kits include an easy-to-use pre-packed spin column for rapid dye removal and high antibody recovery typically greater than 85%. Stabilizing proteins must be removed from the sample before labeling.


Features

  • Convenient—labeled proteins typically ready to use in 90 min (∼15 min hands-on time)
  • High conjugate recovery—pre-packed spin columns generally result in >85 % recovery of antibody conjugate
  • Simple protocol—react, separate, use; detailed instructions included for optional degree of labeling (DOL) determination
  • Rapid purification—quickly remove unbound dye with included pre-packed spin columns in under 15 minutes
