Thermo Fisher, E3481, Epidermal Growth Factor, Tetramethylrhodamine Conjugate (rhodamine EGF)

Quantity: 20 μg We offer several conjugates of epidermal growth factor that are useful for the detection of EGF receptor in cells. Fluorescently labeled EGF has enabled scientists to investigate receptor-membrane interactions, study receptor distribution, calculate rate constants for the interaction of EGF with its receptor, and more. The conjugates incorporating fluorescein (FITC), Oregon Green™ 514, and tetramethylrhodamine were constructed with the dye directly attached to EGF. The conjugates of EGF with Alexa Fluor™ dyes and Texas Red™ dye are complexes of the dye–streptavidin molecule and biotinylated EGF. The biotinylated conjugates utilize biotin-XX, which contains a long spacer arm designed to enhance the probe’s affinity for the EGF receptor.
