Preparing Stock Solutions

Stock solutions

Stock solutions should be made up using the batch specific molecular weight of the product which can be found on:

  • the product vial label
  • the certificate of analysis (CoA) / product information sheet - available online

The Tocris Molarity Calculator is a useful tool to help you make up stock solutions.

Tocriset stock solutions

Tocrisets consist of 3-5 key ligands supplied as lyophilized solids, or pre-dissolved in DMSO at a specific concentration. Each Tocriset has been designed so that 0.5 or 1 ml of a solvent can be added directly to each vial to produce a stock solution of 10 or 5 mM, respectively.
