Bioactivity: 0.2 μg/ mL (100 μ L /Well) immobilized human EpCAM. The dose-response curve of anti-Trop1 antibody EC50 was 8.7 ng/ mL by ELISA. Epithelial cell adhesion molecule (EpCAM), also known as KS1/4, GP40, GA733-2, 17-1A, and TROP-1, is a 40 kDa transmembrane glycoprotein, It consists of an extracellular domain of 242 amino acids (AA) (with two EGF-like repeats), a 23 AA transmembrane segment, and a 26 AA cytoplasmic domain.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
