Possibilities of application of transmembrane enzymes as a biological component of a biosensor for water quality control and detection of toxical substances were performed. Synaptic plasma membranes (SPMs) were adsorbed on nitrocellulose filters. The adsorption of SPMs was followed by determination of the transmembrane enzyme Na,K-ATPase. The optimal conditions for SPM adsorption on nitrocellulose filters were determined: 25 microgram per nitrocellulose filter disc during 1 hour of incubation, on - 20 deg C. The ATPase activity of adsorbed SPM showed, that almost 30% of enzymic activity was detected on nitrocellulose filters in mentioned conditions. This results showed that adsorption of SPM on solid support enhancing enzymatic stability and enable its industrial and analytical application.
