Description	Losartan potassium (DuP-753 potassium) , an Angiotensin II Receptor Blocker, selectively and competitively blocks the binding of angiotensin II to the angiotensin I (AT1) receptor.
Targets&IC50	AT1 receptor:20 nM
In vitro	Losartan competes with the binding of angiotensin II to AT1 receptors. The concentration that inhibits 50% of the binding of angiotensin II (IC50) is 20 nM[1]. Losartan (40 μM) affects ISC but prevents the effect of ANGII on ISC[2]. Losartan significantly reduces Ang II-mediated cell proliferation in endometrial cancer cells. The combination of losartan and anti-miR-155 has a significantly greater antiproliferative effect compared to each drug alone[3].
Cell Research	An MTT assay is used to measure cell proliferation and viability. For the assay, 5000 cells in 200?μL media per well are seeded in a 96 well plate. After overnight incubation to allow for cell attachment, the medium is removed by suction. MTT at 1?mg/mL concentration in serum-free medium is added and then incubated for 4?h at 37°C. After removal of MTT solution, 100?μL of DMSO is added to dissolve formazan crystals. Absorbance at 570?nm and at 600?nm as a reference is then measured using a microplate reader. The difference in absorbance is thus relative to the extent of cell survival.

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
