Background:

Fluorescent dual α9β1/α4β1 integrin inhibitor. Comprises BOP conjugated to Janelia Fluor? 646 (Cat. No. 6148). Fluorogenic: fluoresces only once bound to integrins, enabling hassle-free no-wash experiments. Bright and photostable, enabling live cell tracking of integrin receptors over long time-course experiments. Excitation maximum = 655 nm; emission maximum = 672 nm.
