This purified epidermal growth factor (EGF) contains a single biotin-XX molecule on the N-terminal amino acid. Biotin-XX EGF contains a long spacer arm that enhances the probe’s affinity for the EGF receptor and facilitates binding of a label such as a dye–streptavidin molecule, a Qdot™ nanocrystals–streptavidin molecule, or an enzyme-conjugated streptavidin. 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.Epidermal Growth Factor Specifications:
• EGF molecule: 53 amino acids, MW=6,045 Da
• Number of biotin-XX molecules on each EGF molecule: 1Find Fluorescent EGF Conjugates
In addition to biotinylated EGF, we offer biotinylated EGF precomplexed to selected fluorescent streptavidin labels and EGF directly labeled with some fluorescent dyes. Review Probes for Following Receptor Binding and Phagocytosis—Section 16.1
