Abstract
The spatial variation of changes in intracellular calcium ions were studied with a one-dimensional scanning microphotometer. Changes in intracellular calcium were measured with a metallochromic dye, arsenazo III. Both the magnitude and the kinetics of changes in calcium were dramatically different in different regions of a cell. In Limulus ventral photoreceptors the maximum change was probably restricted to the rhabdomeric lobe.
摘要
用一维扫描显微光度计研究了细胞内钙离子变化的空间差异。用金属显色染料偶氮胂III测量细胞内钙的变化。细胞不同区域钙变化的幅度和动力学都有显著差异。在鲎腹侧光感受器中，最大变化可能局限于视杆叶。
