Product Description
2-Aminopurine is a fluorescent analog of guanosine and adenosine and is a extensively used fluorescence decay-based DNA structural probe. When 2-Aminopurine is inserted into an oligonucleotide, its fluorescence is highly quenched by stacking with native bases. 2-Aminopurine has been used to probe the structure and dynamics of nucleic acids.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
2-Aminopurine's nucleic acid base is greatly quenched by trona when it is incorporated into an oligonucleotide, making it unavailable as a nucleic acid marker. But the precise and accurate fluorescent label for nucleic acid structures is 2-aminopurine, thanks to its extremely sensitive property to inter-base quenching [1]. 6-aminopurine differs from 2-aminopurine merely in the position outside the ring, but its fluorescence intensity is hundreds of times greater than that of purine and adenine [1].

Solubility Data
Solubility (In Vitro)
DMSO : ~5 mg/mL (~37.00 mM)
H2O : ~1.35 mg/mL (~9.99 mM)
Solubility (In Vivo)
Solubility in Formulation 1: 2.5 mg/mL (18.50 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication (<60°C).

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 7.4003 mL 37.0014 mL 74.0028 mL
5 mM 1.4801 mL 7.4003 mL 14.8006 mL
10 mM 0.7400 mL 3.7001 mL 7.4003 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

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
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.
