Product Description
AP 811 is a selective atrial natriuretic peptide clearance receptor (ANP-CR, NPR3) antagonist (inhibitor) with Ki of 0.48 nM. AP 811 is 20,000 times more selective for NPR3 than NPR1. AP 811 eliminates ANP-induced pump stimulation.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
The increased cardiomyocyte proliferation observed at low concentrations of ANP (10 nM) was totally eliminated by AP 811 (10-500 nM) [3].

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 1.0928 mL 5.4639 mL 10.9279 mL
5 mM 0.2186 mL 1.0928 mL 2.1856 mL
10 mM 0.1093 mL 0.5464 mL 1.0928 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box

Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or 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.

Biological Data
  • The concentration-dependent effect of cardiac natriuretic peptides on cardiomyocyte proliferation is controlled by both cGMP and cAMP signaling pathways. (A) The reduced cardiomyocyte proliferation seen with high concentration ANP (10 μM) can be blocked by inhibiting PKG using either Rp-8-pCPT-cGMP (Rp) or KT5823 (KT). *P<0.01 compared with 10 μM ANP alone. (B) The addition of cell-permeable cGMP showed a concentration-dependent reduction of cardiomyocyte proliferation. *P<0.02 compared with control (0 nM). (C) The Npr3-specific antagonist AP-811 could completely abolish the enhanced cardiomyocyte proliferation seen with low concentration ANP (10 nM). Antagonizing Npr3 had no effect on the reduced cardiomyocyte proliferation seen with high concentration ANP (10 μM). *P<0.01 compared with ANP 10 nM alone. (D) Addition of cAMP could abolish the enhanced proliferation seen with low concentration ANP (10 nM). Direct inhibition of adenylyl cyclase with SQ 22536 (SQ) can mimic the enhanced proliferation seen with low concentration ANP (10 nM). Combination of low concentration ANP (10 nM) and 0.5 μM SQ showed an additive effect on proliferation. However, adding low concentration ANP to 5.0 μM SQ showed no increased benefit. *P<0.01 compared with ANP 10 nM alone; #P<0.01 compared with control; **P<0.02 compared with SQ 0.5 μM. Data are expressed as mean + s.e.m.[3]. Jason R Becker, et al. Differential activation of natriuretic peptide receptors modulates cardiomyocyte proliferation during development.
