1922J. Loeb Proteins & Theory Colloidal Behavior ii. 34 If we wish to prepare gelatin or casein free from ionogenic impurities, we must bring these proteins..to the isoelectric point and then wash them. 1955Federation Proc. XIV. 735/1 The electrophoretic mobility of a given protein is a function of the net electric charge and hence of the number of ionogenic groups. 1967Jrnl. Cell. Physiol. LXIX. 287/1 It appears likely..that ionogenic groups of RNA, i.e. phosphate groups, are present at the electrokinetic surfaces of the two cell types. 1972Materials & Technol. V. x. 275 Of the water-soluble surface-active agents.., some undergo ionization when dissolved in water whereas others do not ionize. On this basis, they are divided into two broad groups, namely ionogenic, or ion-forming, and non-ionogenic. |
