Invitrogen Alexa Fluor 700 dye is a dim, near-infrared dye that can be excited with 633-640 nm red lasers. Highly expressed antigens can be labeled with Alexa Fluor 700 in flow cytometry panels allowing for brighter dyes to be used with less-abundant antigens. It fits in a panel between APC and APC-eFluor 780.

We offer Alexa Fluor 700 dye conjugated to a variety of antibodies for cellular labeling and detection. In addition, reactive dye forms and protein labeling kits are available to enable you to generate your own antibody conjugates or probes.
