Abstract
A stabilized, aqueous composition containing FK506. FK506 degrades rapidly in most aqueous matrices. The rate of degradation is decreased in the presence of unfixed blood cells or fragments of blood cells from human or animal sources. A number of matrices using blood components are possible. Blood can be used directly or the blood cells can be lysed. The blood is diluted with a solution of an alkali halide.
