Exactly. Incomplete repression from the associated repressor.


#142670 solubility of adenine

Roughly speaking, the answer is that it is barely soluble.  Adenine is soluble at 20 mg/ml in 1 M HCl, or the hydrochloride is similarly soluble.


#140555 Southern blotting

It doesn't affect the transfer usually. I have always stained my Southern blots with EtBr prior to transfer and never had a problem.  It may slightly retard the blotting step, but with the times (overnight) usually used for this procedure, it shouldn't be a problem.
