Abstract

The major albumin protein in storage parenchyma tissue of developing peas has been localised at an ultrastructural level by immunocytochemistry. Tissue was fixed in buffered aldehyde and embedded in LR White resin which was polymerised by addition of catalyst. Sections were labelled by the indirect method of absorption of Protein A-gold to specifically bound antibodies. This method gives high levels of specific labelling on sections which retain good ultrastructural preservation and have high contrast after conventional staining. The albumin is located throughout the cytoplasm although no labelling was found associated with the endoplasmic reticulum, Golgi apparatus, vacuoles-protein bodies or other organelles.
