Size exclusion chromatography sec analysis
WebbSize-exclusion chromatography continues to be a standard technique for the analysis of monoclonal antibodies and their aggregates. However, as in any SEC method, a thorough … WebbIn this application note, we describe a robust and simple method for poly(A) tail length measurements. The method utilizes the digestion of an mRNA molecule with RNase T1 to liberate poly(A) tail. The digestion products and poly(A) tail are then separated by size-exclusion chromatography (SEC).

Webb22 okt. 2010 · Size-exclusion chromatography (SEC) has a quasi-monopoly on the molecular characterization of polymers in general, and this is also true for branched polymers. The method appeared in the late 1950s and was named gel permeation chromatography (GPC) [ 2] or gel filtration chromatography (GFC) [ 3 ]. WebbThe size range of 4 to 12 µm is traditionally the standard for analytical SEC resins. However, the trend is towards smaller particles of < 2 µm, with the use of ultra high …
