Albumin was measured by the automated HABA-dye technique using sera containing increasing quantities of either free or conjugated bilirubin and the results were compared with those obtained by electrophoresis on cellulose acetate
Polysulfated carbohydrates such as heparin (HP) and heparan sulfate (HS) are not easily amenable to usual ultraviolet matrix-assisted laser desorption/ionization-mass spectrometry (UV-MALDI)-MS analysis due to the thermal lability of their O- and N-SO3 moieties, and their poor ionization efficiency with common crystalline matrices.
