These are data on the uptake of calcium by cells suspended in a
radioactive solution, as a function of time.
Usage
data(calcium)
Arguments
Format
A data frame with 27 observations on the following 2 variables.
time
The time (in minutes) that the cells were suspended in the
solution
cal
The amount of calcium uptake (nmoles/mg)
Details
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.
