Antibody customization doesn't stop after antibody generation. Whether using your custom antibody in immunohistochemistry (IHC), or fluorescent activated cell sorting (FACS), conjugating your antibody allows for simplified detection. Labeling of your antibody with horseradish peroxidase (HRP) provides for sensitive enzymatic detection in IHC. Biotin labeling allows for the flexibility of using a variety of labeled avidin. Finally, labeling your antibody with fluorophores offers a means of direct detection, eliminating the need to juggle multiple secondary antibodies when visualizing or flow sorting with multiple markers. Include our conjugation and labeling services with your custom antibody production for streamlined processing, and even cost savings.
