Analyze Glycoproteins with Sensitive, Quantitative Infrared Fluorescent Techniques

O-Linked Glycan StructureGlycosylation is one of the most common and important events in post-translational modification. Over half of all proteins are believed to be glycosylated, and the resulting glycoconjugates play an important role in many biological processes. They have been connected to instances of cancer development, retrovirus infection, and other diseases. In an effort to understand these diseases, glycoprotein analysis has become a growing area of research. (See examples of typical glycan structures.)

Analysis of glycoproteins requires sensitive and quantitative applications. LI-COR offers a single, optimized solution using the Odyssey® Systems and IRDye® labeled conjugates to analyze glycoproteins. This solution provides sensitive and quantitative results using two-color near-infrared detection at 700 nm and 800 nm wavelengths. Operating at this wavelength produces lower background from biological materials, buffer components, and standard membranes used in Western blotting and lectin binding applications and, thus, superior data.

Outlined below are a variety of applications for several one-color, visible glycoprotein applications that have been adapted to near-infrared fluorescence detection on an Odyssey Imaging System:
