The Benchmark Scientific PR5012TC Accuris SmartCheck Tri-Color Extended Range Protein Markers, 12 Bands, 9 to 245 kDa, 2 x 250μl provide accurate reference points to determine protein size during electrophoresis. SmartCheck markers are compatible with Tris Glycine, Bis-Tris (MOPS) and Bis-Tris (MES) and can be used for western blotting with minimal washout.

Each package of SmartCheck markers includes 2 tubes of 250μl, resulting in less freeze-thaw cycles during product usage thereby extending the shelf life.

The PR5012-TC SmartCheck Tri-Color Regular Range Protein Markers are ready to use standards with 12 pre-stained proteins covering a wide range of molecular weights (note: apparent molecular weight (kDa) of each protein varies slightly with different running buffers). Proteins are covalently coupled with a blue chromophore, and two reference bands (at 25 kDa and 75 kDa) are enhanced in intensity to allow easy visual interpretation. Tri-Color markers are ideal for western blotting applications, as the enhanced green and red bands make it easy to identify the orientation of the blot after transfer.
