Molecular Probes™ Antibody Labeling Kits provide a convenient means to label small amounts of antibodies with the violet light-excitable Pacific Orange™ or Pacific Blue™ dyes. This kit is optimized for labeling 100 µg of antibody per reaction. 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.

Important features of antibody labeling kits:
• Pacific Blue™ has an excitation and emission maximum of 410/455 nm
• Labeled proteins typically ready to use 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)

Better results and workflows with primary labeled antibodies
A primary antibody directly labeled with a fluorophore often produces lower background fluorescence and less nonspecific binding. Further, multiple primary antibodies of the same isotype or derived from the same species can easily be used in the same experiment if they are directly labeled with compatible fluorophores.
