Procainamide labelled glucose homopolymer ladder for use as a calibration standard for HPLC and MS analysis of glycans, 30 runs. The ladder contains glucose homopolymer species from a degree of polymerization (DP) 1 to up to dp 22 (i.e. the glucose monomer GU1-PROC to 22 glucose units GU22-PROC). Glucose homopolymer ladder was obtained by controlled acid hydrolysis of dextran then labelled by reductive amination at the reducing termini with the fluorescent glycan tag procainamide (PROC).
