Description Poziotinib(NOV120101; HM781-36B) is an irreversible HER1/2/4 inhibitor (IC50s: 3/5/23 nM).
Targets&IC50 HER1 :ic50 3.2nM,   HER2 :ic50 5.3nM,   HER4 :ic50 23.5nM,  
Kinase Assay Enzyme activity assay: To determine the IC50 values of HM781-36B for kinase inhibition, enzymes of EGFR, HER2, and HER4 are expressed as recombinant proteins in Sf9 insect cells. Enzyme selectivity screening is then performed using a tyrosine kinase assay kit. Briefly, the reactions are performed in 96 well polystyrene round-bottomed plates containing kinase buffer composed of 100 mM HEPES (pH 7.4), 25 mM MgCl2, 10 mM MnCl2 and 250 μM Na3VO4. The reactions are initiated by the addition of 100 ng/assay enzyme, 100 μM ATP, and 10 ng/mL poly(Glu, Tyr). After 1 h of incubation at room temperature, the reactions are terminated by adding 6 mM EDTA solution and then anti-phosphotyrosine antibody, PTK Green Tracer, and FP dilution buffer mixtures. The fluorescence polarization values are then measured after 30 min at room temperature using a Victor3 microplate reader. Finally, the IC50 values were calculated using the following equation: Y = bottom + (top–bottom)/(1 + 10(X-logIC50)).
Cell Research
Viable cell growth is determined by an MTT reduction assay. Briefly, all cell lines are seeded at a density of 3 × 103 per well in 96-well culture plates and then incubated at 37 °C for 24 h. The cells are then treated with 0.001, 0.01, 0.1, or 10 μM of HM781-36B. Three days later, 50 μg of MTT are added to each well and the samples are then incubated for 4 h to reduce the dye. Next, the samples are treated with DMSO, after which the absorbance of the converted dye in the living cells is measured at a wavelength of 540 nm. Six replicate wells are used for each analysis, and at least three independent experiments are conducted. Data points shown represent the mean while bars represent the SE.(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
