HER2/CD340 Protein, Canine (HEK293, His) is a recombinant, partially truncated canine ErbB2 extracellular domain produced in HEK293 mammalian cells and supplied as a C-terminal His-tagged, lyophilized protein for research applications. It is suitable for biochemical and cell-based assays, including binding and functional activity measurements.
- Recombinant partial extracellular domain (T23-T652) expressed in HEK293 cells.
- C-terminal His tag for purification and detection.
- Supplied lyophilized for extended stability.
- Purity greater than 95% as determined by reducing SDS-PAGE.
- Low endotoxin level (<1 EU/μg), suitable for sensitive assays.
- Store at -20°C; after reconstitution stable 4°C for 1 week or -20°C for long-term storage.
- Demonstrated biological activity with ED50 0.4594 μg/mL in the presence of 0.6 μg/mL trastuzumab.
