Description Rose Bengal sodium is a potent inhibitor of VGlut and vesicular monoamine transporter (VMAT) (Ki of 19 and 64 nM for VGlut andVMAT, respectively)
In vitro Rose Bengal immobilized onto silicon showed good antibacterial activity in the dark under ultrasonic activation[1]
Cell Research Bacteria were grown to a concentration of 10^8 CFU/mL and then diluted with sterile saline by serial decimal dilutions to concentrations of 10^3–10^7 CFU/mL.?Three milliliters of bacterial suspensions was transferred into flat-bottom 2.5 cm diameter 20 mL vials.?Before the experiment, samples were taken from each vial to determine the initial bacterial concentration.?Free Rose Bengal at various concentrations or Rose Bengal immobilized onto silicone was added to all vials, except for the controls.?After adding Rose Bengal, all subsequent procedures were performed under dark conditions.?Vials with bacterial suspensions with or without Rose Bengal were held tight to the bottom of an ultrasonic bath in a plastic holder VU03H ?and treated by ultrasound at a frequency of 38 kHz and a field strength of 4.1 W/cm^3 for 1 to 10 min. After the treatment, 100 μL samples were diluted by several decimal dilutions and were spread over BHA plates with a Drigalsky spreader.?The plates were incubated at 37 °C overnight and the bacterial cell concentration was determined taking dilutions into account using the viable count method, where CFU were counted by means of a colony counter Scan 500.?In control experiments, bacterial cultures were tested in the absence of Rose Bengal without sonication, in the absence of Rose Bengal under sonication and in the presence of Rose Bengal without sonication[1].

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

Calculator the dilution required to prepare a stock solution

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 n 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.
