      Background InformationCell surface of vertebrate cells contains a dense layer of glycans that often terminate with sialic acids, mainly Neu5Ac or Neu5Gc that differ only by a single oxygen atom. Glycoproteins and proteoglycans containing these moieties provide a scaffold for cell-to-cell and cell to environment communication. These sialic acids are mainly present as monosialyl residues at the non-reducing terminus of glycoproteins and play a role in ligand-receptor interactions during fertilization, development, differentiation, and adult brain functions. However, occasionally, sialic acids are linked to each other to form a polymerized structure (poly-sia; poly-Neu5Ac) that can contain 8 to 200 sialyl residues. These glycans are not only modifications of core molecules that are helpful as markers on particular cells, but also have independent functions via their interactions with glycan-recognizing molecules, such as lectins. Neu5Ac is reported to be a prevalent on a variety of sialoglycoconjugates SGCs) in vertebrate brain tissue. Its homopolymeric form (Poly-Neu5Ac) is shown to be most prevalent on the neural cell adhesion molecule (NCAM) and in the capsules of certain neuroinvasive bacteria. NCAM with polymeric Neu5Ac is highly expressed during the embryonic and early postnatal development and plays a critical role in neurite outgrowth and neural plasticity. Poly-Neu5Ac also acts as a neurotropic factor in neuroinvasive E. coli K1 and Neisseria meningitidis serogroup B. The exact mechanisms for breakdown of polymeric forms is not well understood. However, it can undergo an intramolecular self-cleavage into short oligomers under prolonged mild acidic conditions found in lysosomes. Clone 12E3 is highly specific for detection of poly-Neu5Ac glycotype and do not display reactivity towards poly-Neu5Gc. Naito-Matsui, Y., et al. (2017). J. Biol.
