Product Description

Protein Molecular Weight Marker (14 - 120kDa) (Packaged 10 x 200 μL)

Application Notes
Application Notes This product is designed for use in accurate estimation of protein molecular weight in SDS-polyacrylamide gel electrophoresis and western blotting. Thaw the cocktail at room temperature. Gently invert vial several times to ensure that the solution is homogeneous and that any precipitated material is re-dissolved. A loading volume of 5-10μl is appropriate for most gel formats. The markers are optimized for use with Coomassie blue staining, but the loading volume can be adjusted for compatibility with other staining methods (i.e. silver staining).
