ABSTRACT:
A recombinant cell line has a constitutive sialidase whose functional expression is disrupted, for example by homologous recombination or using antisense RNA. Sialidase is purified from cell culture fluid of Chinese hamster ovary cells. Nucleic acid encoding sialidase is obtained using an oligonucleotide probe designed using amino acid sequence data on the sialidase.
