Targets&IC50 COX-1 ,   COX-2
Kinase Assay Effect of inhibition of Acetaminophen on COX-1 and COX-2 activity in human whole blood: For COX-1 assay, aliquots of human whole blood drawn from healthy volunteers without anticoagulant are transferred to glass tubes containing Acetaminophen or DMSO, serum is separated by centrifugation after clotting, and serum TxB2 levels are determined. For COX-2 assay, aliquots of heparinized whole blood are incubated with LPS (10 μg/mL) and aspirin (10 μg/mL), plus Acetaminophen or DMSO for 24 hours at 37 °C, plasma is separated by centrifugation, and PGE2 levels are determined subsequently. The degree of COX-1 or COX-2 inhibition is calculated as the percentage change of plasma eicosanoid (TxB2 for COX-1 and PGE2 for COX-2).Concentration response curves are fitted by a sigmoidal regression with variable slope for both enzymatic assays, and the 50% inhibitory concentration (IC50) values are derived by using of PRISM Version 3.0.
Cell Research
Cells are exposed to Acetaminophen for 48 hours. Cell viability is determined by the trypan blue exclusion method. Intracellular GSH is measured by recording the disulfide, GS-TNB and 5-thio-nitrobenzoic acid (TNB), the yellow colored compound formed by the reaction between GSH with DTNB.(Only for Reference)

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
