Biological Description
Chemical Properties
Storage & Solubility Information
Description MK-0812 is an effective and specific CCR2 antagonist.
In vitro MK-0812 completely blocks all MCP-1 mediated response in a concentration-dependent manner (IC50: 3.2 nM). This value is similar to the potency observed for the inhibition of 125I-MCP-1 binding by MK-0812 on isolated monocytes (IC50 4.5 nM). The addition of MK-0812 to rhesus blood also inhibits MCP-1 induced monocyte shape change. The IC50 for MK-0812 in whole blood assays is 8 nM [1].
In vivo MK0812 (30 mg/kg, p.o.) reduces the frequency of Ly6G-Ly6Chi monocytes in the peripheral blood, while no impact on circulating Ly6G+Ly6C+ neutrophil frequency is observed. In addition, MK0812 treatment causes a dose-dependent reduction in circulating Ly6Chi monocytes and a corresponding elevation in the CCR2 ligand CCL2 [2].
Kinase Assay Human whole blood is collected in EDTA tubes and used within 1 h of blood collection. For antagonist treated samples, blood (200 μL) is pre-incubated with MK-0812 (0.1% final DMSO concentration) for 30 min at room temperature. After this, 20 μL of FITC conjugated anti-CD14 antibody and 4 μL of chemokine or buffer is added to each sample and mixed lightly. An aliquot (100 μL) of the blood mixture is incubated for 10 min at 37°C immediately placed on ice and lightly fixed with 250 μL of ice-cold fixative (49 mL PBS, 1.0 mL 4% paraformaldehyde) for 1 min. Red blood cells are lysed by adding 1.0 mL of ice-cold lysis solution (0.15 M NH4Cl2, 10 mM sodium bicarbonate, and 1 mM EDTA), and incubated for 20 min on ice. After complete lysis of red blood cells, 100 μL of 4% para-formaldehyde is added and the samples are analyzed by flow cytometry for forward scattering measurements [1].
Animal Research Female BALB/c mice are used between 8 and 10 weeks of age. MK0812 are administered in a 0.4% MC solution by 30 mg/kg oral gavage (p.o.). Two hours later, the frequency of CD11b+Ly6G-Ly6Chi monocytes and CD11b+Ly6G+Ly6C+ neutrophils is determined by flow cytometry [2].

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
