February 23, 2012, Lincoln, NE: LI-COR Biosciences introduces the IRDye® (680/800) Protein Marker that is visible in the 700 nm and 800 nm channels of fluorescent imaging systems, such as the Odyssey® family of imaging systems. Grayscale or pseudocolor images of the IRDye Two-Color Marker can be viewed, exported, and used for publishing with both channels visible.
This two-color marker is designed to provide a ladder of convenient and consistent protein sizes (7.5 - 250 kDa) for use with polyacrylamide gels on Western blot membranes. In blot applications, the IRDye (680/800) Protein Marker can be used as a reference for lane or sample orientation.
"The new IRDye two-color protein marker is supplied ready-to-use and contains 12 proteins ranging in size from 7.5 - 250 kDa," says Shawn Mischnick, LI-COR technical product specialist. "This marker adds increased performance for researchers who need to show both channels in a grayscale or pseudocolor image"
Dependent on load volume, this marker can act in a variety of ways: as a pre-stained marker in gels, to visualize the progress of protein separation during electrophoresis. Or to determine the molecular weight of unknown proteins.
