Comparison of ACBP4 and ACBP5 in Arabidopsis leaf and root cells by immuno-gold labeling using transmission electron microscopy.
Transverse sections were stained with affinity-purified ACBP4-specific antibodies (a, d and e) or ACBP5-specific antibodies (b, c and f).
(a) and (b) Transverse sections of leaves stained with ACBP4-specific antibodies (a) or ACBP5-specific antibodies (b).
(c) Magnification of the boxed area in (b).
(d) and (f) Transverse sections of roots stained with ACBP4-specific antibodies (d) or ACBP5-specific antibodies (f).
(e) Magnification of the boxed area in (d).
Arrowheads, gold particles. v, vacuole; cw, cell wall; g, Golgi apparatus; er, endoplasmic reticulum. Bars in (a), (c), (e) and (f) represent 0.2 µm, and in (b) and (d), 2 µm.
