I did my experiment using a competitive enzime ELISA kit and I want to know if I have to calculate B/Bo to compare sample intensities to obtain a percentage bound. Or could I just use the results obtained from the curve?
If you performed your calculations properly, you should obtain the same results for your samples.
My experimental protocol is as follows: I have two groups: - CTL group (sleep and wake ad libitum), rats euthanized in six different ZTs --> ZT0, ZT4, ZT8, ZT12, ZT16 e ZT20. Sleep...
