Paul S Garcia

If the drug has ever been used in another in vivo model, we translate doses by body surface area (BSA). If it has never been tried, test several concentrations on a logarithmic scale (e.g., 0.3 1 3 10 30 100 uM). These might have to be class E tests through your institutional ethics committee.

Thank you Paul sir, for your valuable answer

Mice or rats? A mouse is 30 g, a rat about 300 g. There are web calculators for BSA:
