Table IV. Analysis of the codistribution of marker proteins in peri-Golgi vesicles.

	II
I	Man II	Giantin	KDELr	rBet1
Man II		32.0 ± 2.3	30.8 ± 4.1	8.0 ± 1.6
Giantin	13.6 ± 1.3		5.0 ± 2.5	ND
KDELr	17.1 ± 2.6	4.6 ± 2.1		9 ± 3.4
rBet1	6.3 ± 2.6	ND	ND

Countings comprised 100 Man II-, giantin-, KDELr-, or rBet1-positive vesicles from three different grids. Numbers indicate the percentage (mean ± SEM) of vesicles positive for the protein indicated under I that also labeled for the protein indicated under II. ND, not determined.
