This calculator computes EC80 or EC90 (etc.) from EC50. How?
1. Enter EC50
I will enter:
EC50 as concentration. For 1nM, enter '1e-9'.
log(EC50) as log(concentration, M). For 1nM, enter '-9'.
2. Enter slope factor (Hill slope)
Slope factor =
(If you don't know, enter '1.0'.)
3. Choose your desired EC
Calculate the EC
Enter '80' or '90' ... without the quotes.
