Glycoprotein Analysis 

For the last few decades Glycoproteins have been a subject of interest to biochemists and biologists in many fields. These proteins are found in plasma and other biological fluids and they serve many functions in nearly every physiological process of living organisms.

These macromolecules consist of a peptide chain and one or more carbohydrates linked to them. The simple gradient Method used in this note for the analysis is very reproducible (%RSD about 1.5). The equilibration time between samples is very short and the symmetrical peak is easy to integrate.
