N-Glycosylated mitochondrial proteins?

Is anything known about N-glycosylated proteins in mitochondria? I am
worrying that mithochondria might contaminate my cell membrane
preparation. But since most of my membrane proteins are N-glycosylated
(since they bind conA) I would imagine that they are unlikely to be
mitochondrial in origin? I guess I could assay some mitochondrial marker
protein but would prefer to spend my time and resources more productively.
The membrane prep is a standard homogenization/low speed/high speed
centrifugation fraction.

Appreciate your input.
