OK. As I said, this is not about protein concentration, but let's say I
only have about 6ul of protein sample, so that I can only have *one*
dilution. Would pipetting uncertainty then be considered systematic
error or statistical error?
I am afraid this is a matter of unsettled definitions. By the way, it
wasn't an opinion, more of an option in interpretation. I can say that
whatever is not sampled in a particular experimental setup is systematic
error. Or I can say that (as you seem to suggest, and I like this
option better) that whenever there is a theoretical possibility of
sampling something, it is statistical error even though the particular
setup does not allow accounting for it.
