| Abstract: | A copolymer of styrene and maleic anhydride is modified with low molecular weight polyoles in a very convenient manner, so that it can be applied as a carried for the fixation of biologically active compounds without further pretreatment. The modified products show storage stability over a long time without loss of coupling capacity. Examples for the fixation of trypsin, alkaline phosphatase and a bacterial glutamate dehydrogenase are given, and some properties of the resulting enzyme products are described. |
