Abstract
The in vitro bone marrow assay method for anti-pernicious anemia preparations has been studied. A curve has been constructed showing the relationship between the dilution of liver concentrates at which maximal migration of cells from bone marrow occurred, and the U.S.P. potency of these concentrates. It would appear that this curve may be used for determination of the expected clinical potency of unknown liver extracts.
