Product Description | Recombinant Human Ephrin-A4/EFNA4 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Leu26-Gly171. |
Product Background |
Ephrin A4 is one of the ephrin ligand molecules belonging to the tyrosine kinases receptor family. It was originally identified in a T-lymphoma cell line and seen to be expressed in human adult tissue as well as several tumor types. The cytoplasmic pattern of ephrin A4 could identify a subgroup of primary osteosarcoma patients with a high liability for progression, poor prognosis, and inferior response to chemotherapy. |
