Confocal immunofluorescence localization of the
Menkes ATPase in HeLa cells. Cells were processed for indirect
immunofluorescence and analyzed after incubation with antibodies to the
Menkes ATPase (a, d, g,
and j) and γ-adaptin (AP-1) (b), the
cation-independent mannose-6-phosphate receptor (MPR)
(e), lamp-1 (h), and AP-2
(k). The combined confocal image from each
double-labeling is shown in c, f,
i, and l. (×400.)
