title: A new protocol to prepare dry plant specimens for electron microscopy and immunocytochemistry.
abstract: Samples from dry kidney bean cotyledons were fixed in acrolein vapor and embedded in Lowicryl K4M using a modified dehydration and embedding technique. The preservation of morphology as investigated by transmission electron microscopy was excellent showing desiccated cells and organelles in life-like preservation. Postembedding immunogold labeling for kidney bean purple acid phosphatase (KbPAP) showed association of kbPAP with ribosome-rich areas of the cytoplasm.
