APEX™ Antibody Labeling Kits
![]() | APEX™ Antibody Labeling Kits utilize a unique solid-phase labeling method that enables 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.

How APEX™ Antibody Labeling Kits Work
The APEX™ Antibody Labeling Kits use a solid-phase labeling technique that captures the IgG antibody on the resin inside the APEX™ antibody labeling tip (Figure 1). Any contaminants, including stabilizing proteins or amine-containing buffers, are simply eluted through the tip. After applying the amine-reactive label, a fluorescent IgG conjugate is ready for use in any imaging or flow cytometry application in as little as 2.5 hours with very little hands-on time.
