Fig. 6. Detection of CD55 on wild-type eggs by western blotting. Eggs,
PI-PLC-treated, +, (right lane) or untreated, , (center lane), were
solubilized and separated by reducing SDS-PAGE. PVDF membranes of transferred
proteins were probed for CD55. The left lane is staining from a positive
control lysate of mouse CTLL-2 cells, a line known to express CD55. The
slightly larger size of the CD55 in the CTLL-2 cultured cells may reflect a
difference in CD55 glycosylation.
