Possible adsorption mechanism of high mobility group box 1 protein on a polyacrylonitrile (AN69ST) membrane filter

At ISICEM 2011, we reported that AN69ST showed the highest capacity to adsorb high mobility group box 1 protein (HMGB1) when compared with polymethylmethacrylate, polysulfone and high cut-off membrane [1]. Here we focus on whether filtration or surface heparin on AN69ST by a priming circuit with a heparinized saline contributes to HMGB1, with a heparin-binding protein, adsorption on AN69ST.
