The antibiotic is highly soluble in water and is acid-labile. A typical lab working concentration is 50 µg per ml. It is a semi-synthetic analogue of the naturally occurring benzyl-penicillin.<unk>  at high doses can cause bleeding. Use of<unk>  can cause hypokalemia by promoting potassium loss at the distal convoluted tubule of the kidney. In molecular biology,<unk>  may be preferred as a selecting agent (see Plasmid stabilisation technology) because its breakdown results in byproducts with a lower toxicity than analogous antibiotics like ampicillin.<unk>  is more stable than ampicillin and results in fewer satellite colonies on selection plates. However, in most situations this is not a significant problem so ampicillin is sometimes used due to its lower cost.
