Abstract
Низькотемпературна стабілізація глюкозооксидази в складі біологічного сенсора
Highlights
In recent years the problem of long-term low temperature preservation of biomacromolecules with enzyme activity gained both general biological and ã V.I
1, 2-propane diol and dimethylsulfoxide (DMSO) of chemical pure mark were used as cryoprotectants
Performed investigations showed that after freezing and subsequent thawing there are some changes which can be seen in the structure of absorption spectra of glucose oxidase in UV region
Summary
In recent years the problem of long-term low temperature preservation of biomacromolecules with enzyme activity gained both general biological and ã V.I. Still the usage of enzymes is restricted by their comparatively low resistance at room temperature, the necessity of long-term maintenance of their functional properties during preservation is an important problem for many biosensors. In our researches we used enzyme biosensors on the basis of glucose oxidase, which were first used several decades of years ago. They are still widely used both in medicine and other fields. Surface as a component of biosensors by low temperature For this it was necessary to study the influence of free-thawing and cryoprotective substances on structural-functional properties of glucose oxidase in the solution; to estimate the possibility of using these substances for the preservation of the structure and enzyme activity of the isolated glucose oxidase at low temperatures
