| Description | TFAX 594,SE is a red fluorescent dye that maintains its fluorescence properties regardless of the pH level, ranging from 4 to 10. This dye produces highly intense and photostable conjugates when combined with proteins or antibodies, such as goat anti-mouse IgG. |
| In vitro | Excitation maximum=590±22.5 nm; emission maximum=660±16 nm[1]. Proteins labeled with the TFAX 594,SE dye are several-fold brighter than the same proteins labeled with Texas Red dyes[1]. |
