... Using immumoelectron microscopy, we have determined the subcellular distribution of CaM in corn root cells. Specific immunolabeling for CaM with good ultrastructural preservation was obtained with Epon 812-embedded corn root ceils. Similarly, Hatase et al[12] also showed that there was specific immu ...
