Gamma-Glutamyltransferase Fractions in Human Plasma and Bile: Characteristic and Biogenesis
Figure 5
GGT localization on exosomes by transmission electron microscopy.
Exosomes from A) plasma and B) bile were incubated with a primary antibody directed against GGT and with a secondary 15 nm gold particle-conjugated antibody. After fixation with glutaraldehyde, samples were negatively stained with uranyl acetate and examined under a transmission electron microscope.
