Visible Fluorescent Secondary Antibodies

Use Visible Fluorescent Dye Conjugates for Microscopy and Flow Cytometry

LI-COR’s visible fluorescent dye products include labeled secondary antibodies and labeling kits.

VRDye™ 549, VRDye 490, and IRDye^® 650 secondary antibodies are labeled with visible fluorescent dyes and are optimized for use in Western blotting, microscopy, immunohistochemistry, and flow cytometry applications when imaged on instruments with suitable excitation and emission filters.

These secondary antibodies, like LI-COR IRDye infrared fluorescent secondary antibodies, are highly cross-adsorbed.

The visible fluorescent protein labeling kits are ideal if you need to label your custom monoclonal antibodies for flow cytometry.
