Expression of 9-Oacetylated sialic acids during T cell ontogeny in the adult thymus and on peripheral T cells. This figure summarizes the distribution of 9-O-acetylated sialic acids detected by CHEFcD on developing and on peripheral resting and activated T cells. Varying intensities of CHE-FcD binding are shown as low (lo), intermediate (int) and high (hi) along with a representative percentage of positive cells. Note that while ∼40% of CD4CD8 DN cells are 9-Oacetyllo+, the phenotype of the cells that actually progress to a DP stage is not defined by our current data. Also note that the probe may not detect all ganglioside-bound 9-O-acetyl Sias (see Fig. 14 and Discussion).
