BP005035: Human Ephrin-A4/EFNA4 Protein with the C-His Tag (人 Ephrin-A4/EFNA4 蛋白 C-His 标签)
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.
