[Use of neuraminidase for improving the properties of the erythrocytic ganglioside diagnosticum].

In this work the possibility of using neuraminidase for increasing the content of ganglioside GM1 in the mixture of gangliosides used for the sensitization of erythrocytes has been studied. The study has revealed that the treatment of gangliosides with neuraminidase is sufficient for obtaining active hemosensitin; there is no need for the purification of the preparation by gel filtration.
