Antibody & Protein Labeling Kits

Expand your antibody labeling capabilities
Invitrogen offers a number of Molecular Probes® labeling kits for the direct attachment of intensely fluorescent Alexa Fluor® dyes, R-phycoerythrin (R-PE), or even biotin to less than 10 μg up to 1 mg of IgG antibody. Directly labeled antibodies allow you to use more than one same-species antibody in a single staining experiment. Invitrogen also offers labeling kits for the indirect labeling. Molecular Probes® antibody labeling kits—Your go-to source for antibody labeling.

How Much Antibody Would You Like to Label?

	<1–20 µg Try our Zenon® Labeling Technology which provides a rapid, versatile, and reliable method for producing non-covalent, fluorescently labeled antibodies, even with small amounts of unpurified starting material.			10–20 µg APEX™ Antibody Labeling Kits provide an efficient, convenient and reliable method for covalently attaching fluorescent labels to very small amounts of IgG antibody in the presence of any contaminants including stabilizing proteins and amine-containing buffers.

	10–100 µg Microscale Protein Labeling Kits conveniently label small amounts of purified protein (MW between 12 and 150 kDa) with a bright, photostable Alexa Fluor® dye or the hapten, biotin-XX.			100 µg Directly label monoclonal and polyclonal antibodies with Molecular Probes® Monoclonal Antibody Labeling Kits and eliminate background staining commonly observed with secondary antibodies and use more than one same-species antibody in a single experiment.

	1 mg Our Protein Labeling Kits provide a nearly effortless way to stably label larger amounts of IgG antibody with a fluorescent dye or hapten in 2 hours.			0.5–3 mg The SAIVI™ Rapid Antibody Labeling Kits are uniquely designed to provide the rigorous requirements to control the degree of labeling (DOL) using our near-infrared (NIR) AlexaFluor® dyes.
