Convenient set containing three ready-made solutions for easy and fast casting of sequencing gels. Solutions are produced in ROTIPHORESE® quality and are perfectly matched - providing superior, reproducible quality and high sequence resolution.
In addition, the ROTIPHORESE®Sequencing system allows flexible adaptation to the desired gel variant, so that the amount of urea can be varied in addition to the acrylamide concentration. By using the ROTIPHORESE®Sequencing gel buffer concentrate and ROTIPHORESE®Sequencing gel diluent contained in the set, gels with 50 % urea content are obtained. By adding defined quantities of ROTIPHORESE®10x TBE buffer or water, the urea content can be reduced to up to 40 %.
Handling is most simple: Measure and mix certain amounts of all three components, add APS and TEMED, and cast the gel. We recommend using the Carl ROTH sequencing electrophoresis chamber (Art. no. AE28).
Ready-to-use, aqueous 50 % urea stock solution.
For the preparation of polyacrylamide sequencing gels with 40-50 % urea (6,7-8,3 M).
Also part of the ROTIPHORESE®DNA sequencing system (Art. No. A431.1).
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.
The right choice for each and every application
The large variety of different ROTIPHORESE® solutions provides you with the right product for each and every application. ROTIPHORESE® gel solution may be used both in protein and nucleic acid electrophoresis. ROTIPHORESE® ready-to-use solutions for manual sequencing facilitate the preparation of sequencing gels of a constant high quality - also suitable for automatic sequencers.
ROTIPHORESE®Gel 30 and Gel 40 are ready-to-use, gas-stabilised acrylamide solutions with different concentrations and with different ratios of acrylamide to bisacrylamide. ROTIPHORESE® ready-to-use solutions can be used directly.
