| Preparation method | Culturing BT-12 rhabdoid tumor cells (10 000 cells) in 2.0 mL of 0.35% soft agar containing 0.5× RPMI medium, 7.5% FBS, and the indicated concentrations of 10 or DMSO vehicle only and overlaid with 0.5 mL of 1× RPMI medium containing 15% FBS and 10 or DMSO vehicle only. Refreshing medium and 10 or vehicle twice a week. Staining colonies with thiazolyl blue tetrazolium bromide and counting after 3 weeks. Colo699 NSCLC cells (15 000 cells) are cultured in 1.5 mL of 0.35% soft agar containing 1× RPMI medium and 10% FBS and overlaid with 2.0 mL of 1× RPMI medium containing 10% FBS and the indicated concentrations of 10 or DMSO vehicle only. Refreshing medium and 10 or vehicle 3 times per week.Staining colonies with nitrotetrazolium blue chloride and counting after 2 weeks. |

| 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.
