Ultrastructural distribution of Ca ++ within neurons

We used the oxalate-pyroantimonate technique to determine the ultrastructural distribution of Ca ++ in neurons of the rat sciatic nerve. The content of the precipitate was confirmed by X-ray microanalysis and appropriate controls. In the cell bodies of the dorsal root ganglia, Ca ++ precipitate was found in the Golgi, mitochondria, multivesicular bodies and large vesicles of the cytoplasm but not in lysosomes, and was prominently absent from regions of rough endoplasmic reticulum and ribosomes. It was seen in the nucleus but not in the nuclear bodies or nucleolus.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47408/1/418_2004_Article_BF00492588.pd
