Cell Research
To induce hypertrophy, myocytes were treated for 10 min or 24 h as appropriate and noted under Results with 10 μM phenylephrine in the absence or presence of the following agents: the NHE-1 inhibitor EMD87580 (5 μM) or cariporide (5 μM), the JNK1/2 inhibitor SP600125, the p38 inhibitor SB203580, the ERK1/2 inhibitor PD98059 (all at 10 μM), and the reverse mode Na+-Ca2+ exchange inhibitor KB-R7943 or SN-6 (both at 10 μM). All drugs were added 30 min before the addition of phenylephrine [1].
Animal Research
Two groups were studied. The treatment group (n = 5) received EMD 87580 at a dose of 5 mg/kg IV bolus 5 min before aortic cross-clamping and 10 mol/L EMD 87580 in the cardioplegic solution. The control group (n = 9) received the same volume of saline vehicle. Systemic pretreatment was used to ensure drug availability during the ischemic period prior to CPA. Direct infusion via cardioplegia ensures drug delivery at the time of ischemia (CPA), and it decreases the variability of drug delivery that may occur during the hemodilution with CPB initiation. Incorporation into the cardioplegia also minimizes the potential variable of drug/extracorporeal circuit interactions. Using this dosing regimen, the plasma concentration of EMD 87580 was in the 2,500 to 3,000 ng/mL range at 10 min after CPB. This concentration has been shown to be effective at Na+/H+ exchanger inhibition in vitro [2].

Molarity Calculator allows you to calculate the

  • mass of a compound required to prepare a solution of known volume and concentration
  • volume of solution required to dissolve a compound of known mass to a desired concentration
  • concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

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
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
