TROP2 Protein Interaction

Recombinant TROP2 Protein Feature

TROP2 Protein, Mouse, Recombinant (Fc Tag)

High Purity
> 95 % as determined by SDS-PAGE
Low Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
High Activity
Measured by the ability of the immobilized protein to support the adhesion of U937 human histiocytic lymphoma cells. When 5 x 10E4 cells/well are added to coated plates (40 μg/mL, 100 μL/well), > 50% cells will adhere after 1 hour at 37℃.
