Reappearance in vivo of neuraminidase-sensitive sialic acid in L 5222 rat leukemia cells.

Cell electrophoretic data and quantitative sialic acid determination show that, 16 to 20 h after i.p. implantation of neuraminidase-treated L 5222 rat leukemia cells, the original sialic acid content at the cell periphery is reconstituted.
