Preparing Stock Solutions
The following data is based on the product molecular weight 228.2. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||4.38 mL||21.91 mL||43.82 mL|
|5 mM||0.88 mL||4.38 mL||8.76 mL|
|10 mM||0.44 mL||2.19 mL||4.38 mL|
|50 mM||0.09 mL||0.44 mL||0.88 mL|
The reconstitution calculator allows you to quickly calculate the volume of a reagent to reconstitute your vial. Simply enter the mass of reagent and the target concentration and the calculator will determine the rest.

Epigenetics Scientific Review
Written by Susanne Müller-Knapp and Peter J. Brown, this review gives an overview of the development of chemical probes for epigenetic targets, as well as the impact of these tool compounds being made available to the scientific community. In addition, their biological effects are also discussed. Epigenetic compounds available from Tocris are listed.
