Description GW788388 is a potent and selective inhibitor of ALK5, also inhibits TGF-(beta) type II receptor and activin type II receptor activities.
Targets&IC50 ALK5:18 nM
Kinase Assay ALK5 Fluorescence Polarization Binding Assay: GW788388 binding to ALK5 is tested on purified recombinant GST?ALK5 (residues 198-503). Displacement of rhodamine green fluorescently labeled ATP competitive inhibitor by different concentrations of GW788388 is used to calculate a binding pIC50. GST?ALK5 is added to a buffer containing 62.5 mM N-(2-hydroxyethyl)piperazine-N'-2-ethanesulfonic acid (Hepes), pH 7.5, 1 mM dithiothreitol (DTT), 12.5 mM MgCl2, 1.25 mM 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonic acid (CHAPS), and 1 nM rhodamine green-labeled ligand so that the final ALK5 concentration is 10 nM based on active-site titration of the enzyme. The enzyme/ligand reagent (40 μL) is added to 384-well assay plates containing 1 μL of different concentrations of GW788388. The plates are read immediately on a LJL Acquest fluorescence reader with excitation, emission, and dichroic filters of 485, 530, and 505 nm, respectively. The fluorescence polarization for each well is calculated by the Acquest and is then imported into curve-fitting software for construction of concentration?response curves.
Cell Research Cell viability/proliferation assays are done according to the manufactures instructions (CellTiter 96 Aqueous One Solution Cell Proliferation Assay). Viability and proliferation are measured after 72 hours GW788388 treatment in the presence or absence of TGF-β.(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.
