Kinase Assay In Vitro Bcr-Abl Kinase Assays: Bcr-Abl complexed to SHIP2 is immunoprecipitated from cell lysates of K562 cells maintained in log-phase culture conditions. Complexes are collected on protein A-Sepharose, and complexes are washed three times in lysis buffer and then washed twice in abl kinase buffer [50 mM Tris (pH 8.0), 10 mM MgCl2, 1 mM DTT, 2 mM p-nitrophenylphosphate, and 2 μM ATP; New England Biolabs Buffer and protocol]. Kinase assays are performed with 10 μM [γ-32P]ATP/sample for 15–60 min at 30°C in the presence or absence of the indicated concentrations of drug. The reaction is stopped by the addition of SDS-PAGE sample buffer and heated at 100°C for 10 min. Proteins are separated on 7.5% SDS-polyacrylamide gels, gels are dried under vacuum, and phosphorylation is visualized by autoradiography on X-ray film.
Cell Research Cell growth is determined by two methods. For the [3H]thymidine assay, cells (104 cells/well) are cultured in 96-well, round-bottomed plates with diluted DMSO (control) or with varying concentrations of a specific compound that is resuspended in DMSO for 48 h at 37°C. [3H]Thymidine is added at a concentration of 1 μCi/well, and cells are incubated for an additional 18 h. Cells were harvested with the Unifilter system, scintillation fluid (25 μl/well) is added to each well, and [3H]thymidine incorporation is determined on a Packard Scintillation Counter. Data points for all assays are obtained in triplicate, and background incorporation from cell-free wells is determined and subtracted from all data points. For cell viability, control and drug-treated harvested cells are counted on a hemocytometer using the trypan blue dye exclusion method.(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 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.
