ProtocolIn VitroRo3280 shows strong activity in H82, H69, A549 lung cancer cell lines, EC50 6 nM, 7 nM, and 82 nM, respectively. Ro3280 also inhibits several other cancer cell lines at lower concentrations
In VivoRo3280 (RO3280, 40 mg/kg, iv) inhibited tumor growth by 29% in mouse xenograft models implanted with HT-72 colorectal cancer cells, and RO3280 completely inhibited tumor growth when administered more frequently

Calculation Results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid concentration mg/mL) ,Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
