Immunoaffinity columns using antibodies as ligands against mammalian proteins could be used for different applications in protein expression control and, if a standard available, for direct protein quantification in complex sample solutions. Additionally, these columns are ideal for polishing step of recombinant proteins, such as mammalian receptor Fc fusion proteins. Most importantly, such columns could extract a significant amount of a single membrane protein from native source, suitable for downstream analyses, such as mass spec analysis of their glycans.
Immunoaffinity chromatographic monoliths against RAE-1 GPI anchored glycoprotein were developed (CIMmic HDZ – @RAE-1 column) as a part of Glycomet project with the main goal to analyze the antigen glycoprofile.
