our experimental results demonstrate that concanavalin a ( con a ) receptors on embryonic muscle cells normally accumulate at the cathodal side of the cell , but that they can be induced to accumulate at the anodal side of the cell by preincubating the myotubes either with neuraminidase , a treatment that removes negatively charged sialic acid residues , or with the lipid dii , a treatment that adds positive charges to the surface of the cell .
