A unique structural feature of the neural cell adhesion molecule N-CAM is the presence of homopolymers of alpha (2----8)-linked sialic acid units. We have used two specific probes for the detection of poly(sialic acid) in normal human kidney and Wilms

The structurally similar polysialic acid capsules of group B meningococci and Escherichia coli K1 are poor immunogens, and attempts are currently being made to improve their immunogenicity by chemical modifications. An IgG monoclonal antibody to these polysialic acid capsules was

We report the presence of alpha(2----8)-linked polysialic acid as detected with a monoclonal antibody outside the nervous tissue in the postnatal developing rat kidney. By immunoblot analysis, the reactivity was confined to a broad band of apparent molecular mass 200-250

The neural cell adhesion molecule (NCAM) is the major carrier of polysialic acid (PSA) which modulates NCAM functions of neural cells at the cell surface. In previous studies, we have shown that stimulation of cultured neurons with surrogate NCAM ligands
