The present invention discloses a single population of simulated leukocyte granules prepared from mammalian whole white blood cells, which is useful in calibrators for a hematology analyzer, a calibrator comprising the single population of simulated leukocyte granules, and a method of preparing the single population of simulated leukocyte granules. The method of preparing single population of simulated leukocyte granules according to present invention comprises the steps of: obtaining mammalian whole white blood cells; treating the mammalian whole white blood cells under the action of a hemolytic agent in the presence of a leukocyte treating liquid, i.e., an isotonic saline solution comprising a fixative, a oxidizer and a carbohydrate; fixing the treated mammalian whole white blood cells with a fixative; and suspending the fixed cells in a preservation medium suitable for long-term preservation of fixed cells.
