ROTI®Stock 20 % SDS, BioScience-Grade, ready-to-use, filtered (0,2 µm), 1 l

ROTI®Stock 20 % SDS, BioScience-Grade is a ready-to-use sodium dodecyl sulfate solution for protein electrophoresis and PAGE gel preparation. The 20 % stock is filtered at 0,2 µm and supplied in a 1 l pack for convenient dilution into sample buffers, running buffers, and gel recipes used in vertical electrophoresis. Density is approximately 1 g/cm³, with a boiling point around 100 °C, reflecting the aqueous detergent concentrate. This BioScience-Grade SDS stock from manufacturer Carl ROTH supports standard workflows in polyacrylamide gel electrophoresis where controlled SDS concentration is essential for denaturing protein separation. The pre-filtered, ready-to-use format helps laboratories avoid handling powdered SDS and maintain consistent detergent strength across gel casting and sample preparation. Suitable for routine PAGE setup and related electrophoresis applications, the 1 l volume serves frequent users who prepare multiple gels or buffers from a common stock. Use according to established molecular-biology protocols when incorporating SDS into denaturing gel systems and protein sample treatments.
