The present invention is drawn to a hematology control made from particles a particle having a biopolymer attached to a surface of the particle. The particle simulates a component of a blood sample, such as a reticulocyte or nucleated red blood cell component of a blood cell sample in a flow cytometer or hematology analysis instrument. The present invention is further drawn to methods of making and using the hematology control.

Hematology controls for reticulocytes and nucleated red blood cells

An improved blood suspension media for hematological compositions, having particular utility with a red blood cell component for devices using electronic and optical means for blood determinations, and processes for using the suspension media. The suspension media finds particular utility in providing the hematology control product with a stable and consistent MCV and RDW for an extended product shelf life.

Hematology control product with increased closed vial stability

The present invention relates to a hematology control product for automated hematology instruments containing an aqueous solution of at least one blood cell analog, an absorbance agent in an amount sufficient to simulate a hemoglobin concentration, and a stabilizing agent in an amount sufficient to stabilize the size of the blood cell analog when the control product is subjected to temperature ranging from -15.degree. C. to 45.degree. C. The control product does not require controlled temperature storage for product stability. In addition, a novel method of using a hematology control product is provided wherein the control product contains a single blood cell analog and is used to simulate both red blood cells and white blood cells on an automated hematology instrument.

Stable hematology control composition and method of use

A method for modulating the specific activitiy of a target protein which is being purified. A controller protein is added to the target protein prior to conducting a final purification step in a purification process.

Method for modulating specific activity of inteferon alpha
