Kinase Assay Kinase assays: Purified kinase domains are incubated with PP-121 at 2- or 4-fold dilutions over a concentration range of 1nM-50 µM or with vehicle (0.1% DMSO) in the presence of 10 µM ATP, 2.5 µCi of γ-32P-ATP and substrate. Reactions are terminated by spotting onto nitrocellulose or phosphocellulose membranes, depending on the substrate; this membrane is then washed 5–6 times to remove unbound radioactivity and dried. Transferred radioactivity is quantitated by phosphorimaging and IC50 values are calculated by fitting the data to a sigmoidal doseresponse using Prism software.
Cell Research
For western blot analysis, cells are grown in 12-well plates and treated with PP-121 at the indicated concentrations or vehicle (0.1% DMSO). Treated cells are lysed, lysates are resolved by SDS-PAGE, transferred to nitrocellulose and blotted. For cell proliferation assays,cells are grown in 96-well plates are treated with PP-121 at 4-fold dilutions (10 µM - 0.040 μM) or vehicle (0.1% DMSO). After 72 hours cells are exposed to Resazurin sodium salt (22 µM) and fluorescence is quantified. IC50 values are calculated using Prism software. For proliferation assays involving single cell counting, non-adherent cells are plated at low density (3–5% confluence) and treated with PP-121 (2.5 µM) or vehicle (0.1% DMSO). Cells are diluted into trypan blue daily and viable cells counted using a hemocytometer. For apoptosis and cell cycle analysis, cells are treated with the indicated concentration of PP-121 or vehicle (0.1% DMSO) for 24–72 hours. Cells are either stained live with AnnexinV-FITC or fixed with ethanol and stained with propidium iodide. Cell populations are separated using a FacsCalibur flow cytometer; data is collected using CellQuest Pro software and analyzed with either ModFit or FlowJo Software.(Only for Reference)

Molecular Weight Calculator

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 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.
