... Adsorption of proteins on precipitated high porous silica and silica gel . Abstract Adsorption characteristics of proteins on high porous silica (specific surface area 580 mVg and apparent density 0,26 g/cm3) and on silica gel (600 mz/g and 0,53 g/cm3) are compared. ... Maximum adsorptions on high porous silica for gamma-globulin (M 150 000) and hemoglobin (M 64 000) are 10 and 5 times greater than on silica gel respectively. ...
