Proteins at the Cell Surface (a) Biotinylation of WunM3 and WunGFP at the cell surface. Washes = non-biotinylated proteins; Eluates = biotinylated cell surface proteins. We used internal tubulin as a negative control and the cell surface marker CD2 as a positive control (data not shown). (b) EM shows both proteins at the cell surface, with WunM3 present in sub-cortical vesicles.
