Description AG14361 is an effective inhibitor of PARP1 (Ki<5 nM).
Targets&IC50 PARP1:<5 nM(Ki)
Kinase Assay PARP-1 Activity Assays: The activity of full-length recombinant human PARP-1 is measured in a reaction mixture containing 20 nM PARP-1, 500 μM NAD+ plus [32P]NAD+ (0.1–0.3 μCi per reaction mixture), and activated calf thymus DNA (10 μg/mL) at 25oC; the reaction is terminated after 4 minutes by adding ice-cold 10% (wt/vol) trichloroacetic acid. The reaction product [32P]ADP-ribose incorporated into acid-insoluble material is deposited onto Whatman GF/C glass fiber filters with a Bio-Dot microfiltration apparatus and quantified with a PhosphorImager. Inhibition of PARP-1 activity by AG14361 at 0–600 nM is measured, and the Ki for AG14361 is calculated by nonlinear regression analysis.
Cell Research LoVo and SW620 colorectal cancer cells and A549 non–small-cell lung carcinoma cells are maintained in RPMI-1640 medium containing 10% fetal calf serum. Cell growth inhibition is estimated in exponentially growing LoVo, A549, and SW620 cells in 96-well plates. Cells are exposed to AG14361 (0–20 μM) alone or in the presence of 400 μM temozolomide. After 5 days of culture, these cells are fixed with 10% trichloroacetic acid and stained with sulforhodamine B. The concentration of temozolomide, topotecan, and AG14361 alone or in combination that inhibits growth by 50% (GI50) is calculated from computer-generated curves. Recovery from potentially lethal damage is measured in confluent LoVo cell cultures arrested in G1 phase to mimic the radiation-resistant quiescent cell population in tumors. Such cells are exposed to 8 Gy of γ-irradiation and then harvested and plated for colony formation assay immediately or maintained as growth-arrested confluent cultures for a 4-hour or 24-hour recovery period before harvesting and plating for the colony formation assay. Where indicated, 0.4 μM AG14361 is added 30 minutes before irradiation and is present in the recovery incubation. (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

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.
