アンチモン酸カリウム法によるVX2癌細胞内カルシウム局在の検討

抄録

Calcium is an essential metal and important mineral as a body component. The intracellular calcium localization in VX2 carcinoma cells was studied at an ultrastructural level by potassium antimonate technique and x-ray microanalysis. The use of nylon grids which are coated with carbon for x-ray microanalysis allowed a peak of calcium and the precipitates were found to be of calcium compound. The calcium antimonate complex was shown to be most prevalent at the euchromatin and mitochondria. The present study was conducted in order to elucidate the exact intracellular site of calcium storage and to provide some aspects on the calcium metabolism that might occur in VX 2 carcinoma.
