I performed a titration treatment on cells in 2 replicates and then detected an antibody in the supernatant using ELISA. I have my corrected measures and standards, sample concentrations and SD error bars, but I don't know how to decide how significant the average of each of my 2 repeats are. These are my readings. I calculated the coefficient of variation (CV), but I wouldn't know how significant this data is. I'm used to having p values dictate how accurate the data is, but should it be applied in my case?
