1. p-aminobenzene sulphonyl ethyl-(ECD)-agar has been obtained by reaction of 8% epichrolohydrin-orosslinked desulphate (ECD) agar with p, β-(sulphato ethyl sulohonyl) aniline (SESA) in an alkaline medium at above 60%. The optimal pH of etherization is 10. A series of ABSE-(ECD)-agar possessing 107-1216 μmoles of aromatie amine/g dry weight of support have been prepared by controlling the amount of SESA added.2. The diazonium salts of ABSE-(ECD)-agar easily coupled with nuclease P_1 at pH 6.4-8.0. The activity recoveries of immobilized nuclease P_1 were 18-35%. In this case, 1 g of support can bind 105-120mg of protein and 4280 units of nuclease P_1.3. In the coupling reaction, the presence of ammonium in the medium could increase the activity of immobilized nuclease P_1, but its stability was less than that of the control.4. The support containing 1216 μmoles aromatic amine per gram of agar bound more protein, but the immobilized enzyme showed less biological activity.5. α-naphthol was used to "block" the residual diazonium salts on the immobilized enzymes. The stability of immobilized nuclease P_1 thus obtained was distinctly improved.

Different kinds of porous glasses with pore diameter from 80Ato 1500 A suitable forimmobilization ot enzymes were prepared by means of changing the composition of Na_2O-B_2O_3-SiO_2 glasses.Porous glass for immobilization of glucoamylase,its pretreatment andconditions for immobilization have been investigated.It is found that, for the optimumpore diameter, the activity of immobilized glucoamylase increases with the increase ofsurface area and decrease of particle size of porous glass. Pretreatment of porous glass withalkali solution can greatly increase the activity of immobilized glucoamylase.
