Biochemical Reactions of Cells Treated with Puromycin

SUMMARY:

The Puromycin data frame has 23 rows representing the measurement of initial velocity of a biochemical reaction for 6 different concentrations of substrate and two different cell treatments. Most of the concentration levels were tried twice. All of the data is numeric. This data frame contains the following variables (columns):

ARGUMENTS:

conc
the concentration of the substrate.
vel
the initial velocity of the reaction.
state
a factor telling whether the cells involved were treated or untreated.

The data are from a biochemical experiment where the initial velocity of a reaction was measured for different concentrations of the substrate. Data are from two runs, one on cells treated with the drug Puromycin, the other on cells without.

EXAMPLES:

attach(Puromycin) 
plot(conc, vel, type = "n") 
text(conc, vel, ifelse(state== "treated", "T", "U"))
