Unstained Protein Laddder
The Unstained Protein Ladder is a mixture of 12 unstained recombinant proteins covering a wide range of molecular weights from 10 to 200 kDa. The proteins resolve into clearly identifiable bands when separated on the SDS-PAGE gel (MES buffer), with the intensified 25kDa and 85kDa protein bands serving as the two reference bands.
Please note that this ladder is not stained. The bands will become visible only once you stain your gel with a generic method, such as Coomassie blue.
