Product Description |
Recombinant Canine EGF-Protein is expressed from E.coli with His tag at the N-terminus.It contains Asn973-Arg1024. |
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. |
