    Analytical and Assay Core

    The Analytical and Assay Core is a core facility in the Department of Physiology and Biophysics. Its main goal is to provide support for various radioimmunoassays, enzyme-linked immunoassays (ELISA), molecular and chemical analyses.

    These facilities and services are available to all members of the department and to collaborators at UMMC as well as other educational and research institutions.

    The specific aims of this core are the following:

    • To provide and ensure uniform methods for collection, labeling, transporting, storage and analysis of various biological samples, including plasma, urine and tissues.
    • To provide accurate and timely analyses of urine, plasma and tissue samples
    • To provide supervision of commonly used analytical procedures, thereby reducing the duplication of effort that would otherwise be required.
    • To provide maintenance for equipment used by multiple investigators in different projects in the department and to train new personnel in the proper use of the equipment.
    • To provide hardware and software for computerized collection and retrieval of data from radiation counters.
    • To reduce the expenditure of research funds by bulk purchasing of supplies at discount and by allowing equipment, instruments and facilities to serve multiple investigators.
    • To provide expertise and equipment to develop new assays and improve existing assays.
    • To provide personnel needed to ensure compliance with state and federal regulations in radiation safety, and handling of blood-borne pathogens and hazardous chemicals. 

    The Analytical and Assay Core is located on the fourth floor (room G475) of the Guyton Research Center. The core serves as a resource for the Department of Physiology and Biophysics, collaborators at UMMC as well as other educational and research institutions on a fee-for-service basis.

    Haiyan Zhang serves as the laboratory manager. She has more than 20 years' experience in performing radioimmunoassays and other biochemical assays. Dr. Barbara T. Alexander is the overall core leader and coordinates administrative and budgetary components of the Analytical and Assay Core.
