20 % stock solution sodium dodecyl sulphate.
Store the solution away from light in a dry place. SDS stock solution and other solutions containing SDS can precipitate easily at room temperature. The crystals can be resolubilised by brief heating them between 30 to 50 °C. Prolonged heating above 30 °C should be avoided, otherwise hydrolysis of the SDS and formation of fatty alcohols may occur.
Safe
Acrylamide ia a strong nerve poison which has clearly proved to be carcinogenic and to change the genetic make-up during animal testing. Acrylamide is resorbed primarily through the skin. The formation of dust when working with the solid matter is particularly critical. A hazard which can be easily avoided by using the ROTIPHORESE® ready-to-use solution.
Superior quality
ROTIPHORESE® Acrylamide and -Bisacrylamide solutions from Carl ROTH have the highest purity level. They are produced from substances free from acrylic acid. Oxidation products are removed from the solution by a selective absorption process. A new formation of such and/or polymerisation of the solution is prevented by gaseous stabilisation of the solution.
In order to guarantee a high consistency of our ROTIPHORESE®-solutions, each batch undergoes electrophoretic testing.
