Howard Grimes from the Botany Department, North Carolina State University, conducted an experiment for biochemical analysis of intracellular storage and transport of calcium across plasma membrane. Cells were suspended in a solution of radioactive calcium for a certain length of time and then the amount of radioactive calcium that was absorbed by the cells was measured. The experiment was repeated independently with 9 different times of suspension each replicated 3 times.
霍华德·格兰姆斯从北卡罗来纳州立大学植物学系,进行单元内钙的储存和运输的跨单元膜的生化分析实验。单元悬浮在一定的时间长度和放射性钙的解决方案,然后被单元吸收放射性钙的量测。 9个不同的次暂停,各重复3次独立重复实验。
