Protocol

Kinase Assay:[1]
+ Expand

In-vitro inhibitory enzyme kinetic assays:

The assays are carried out in triplicate using the ATP/NADH coupled assay system in a 96-well format. The final reaction mixture contains 0.5 mg/mL Bovine Serum Albumin (BSA), 2 mM MnCl2, 1 mM phospho(enol) pyruvic acid (PEP), 1 mM TCEP, 0.1 M Hepes 7.4, 2.5 mM poly-[Glu4Tyr1] peptide, 1/50 of the final reaction mixture volume of pyruvate kinase/lactic dehydrogenase enzymes from rabbit muscle, 0.5 mM NADH, 0.5 μM EGFR kinase, 100 μM ATP and varied amount of WZ3146. WZ3146 and ATP are mixed and made separate stock from the mixture with all other ingredients and added last to the latter to start the reaction. Steady state initial velocity data are drawn from the slopes of the A340 curves.
Cell Research:[1]
+ Expand
  • Cell lines: NSCLC and Ba/F3 cells
  • Concentrations: 0-10 μM
  • Incubation Time: 72 hours
  • Method: Growth and inhibition of growth is assessed by MTS assay. NSCLC or Ba/F3 cells are exposed to treatment for 72 hours and the number of cells used per experiment is determined empirically. All experimental points are set up in six to twelve wells and all experiments are repeated at least three times. The data is graphically displayed using GraphPad Prism version 5.0 for Windows. The curves are fitted using a non-linear regression model with a sigmoidal dose response.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

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.
