WebDec 17, 2014 · The highest amount of BSA absorbed on the silica surface was observed at pH 4.6 [the value close to the BSA isoelectric point (pI)], which is primarily related to the packed albumin conformation and the lack of adsorbent–adsorbate electrostatic repulsion. At pH 4.6, largest mass decrease was also noticed (thermogravimetric measurements). WebHere the isoelectric point of the preparation filtered without acidification was at pH 6.65 and that of the preparation filtered after acidification (3 cc. of 0.1 N HCl to 50 cc. of 1: 10 laked cell stock), i.e. the one most nearly free from non-hemoglobin protein, was at pH 6.77. WebThe isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean.The standard nomenclature to … how to reselect text in paint
