Product Description | Recombinant Human EGF Protein is expressed from HEK293 with hFc tag at the N-Terminus.It contains Asn971-Arg1023. |
Product Background |
The epidermal growth factor (EGF) family of peptides encodes several proteins that can function as growth factors. The EGF-like peptides, with the exception of proteins of the EGF-CFC subfamily, bind and activate tyrosine kinase receptors that belong to the erbB family. |
