On an inhibition curve, the IC50 for an antagonist is seen to be directly above the number 8 on the x-axis, which is labeled -Log(drug). What concentration of drug is the IC50?
in M
in nM
2. Corrected_text: For the drug in Q1, above, what PERCENT of the receptors is occupied by the antagonist when the concentration on the inhibition curve is directly above the number 9?
3. Corrected_text: For the drug in Q1, above, what FRACTION of the receptors is occupied by the antagonist when the concentration on the inhibition curve is directly above the number?
4. Corrected_text: For the drug in Q1, above, if the radioligand concentration is 1 nM and the Kd of the radioligand is 0.1 nM, what is the Kd value of the drug? Specify units.
