Histocompatibility & Engraftment Monitoring Core

At the Histocompatibility & Engraftment Monitoring Core of the Comprehensive Transplant Center, our mission it to:

  • Provide high-quality histocompatibility services to all investigators in the Feinberg School of Medicine and the larger Northwestern University research community
  • Develop state-of-the-art assays to improve selection and monitoring for solid organ and stem cell transplantation
  • Provide consultation on all aspects of histocompatibility testing in transplantation, autoimmunity, infectious diseases and allergy

The core is under the direction of co-directors David F Pinelli, PhD, F(ACHI) and Anat Tambur, PhD, DMD, F(ACHI), and associate director Aleksandar Senev, MD, PhD, F(EBTI), S(ACHI). The core also includes a laboratory manager, two supervisors, post-doctoral directors in training, and senior and junior technologists with extensive experience in tests related to solid organ and stem cell transplantation.

The Transplant Immunology Laboratory is accredited by the American Society for Histocompatibility and Immunogenetics, and Dr. Pinelli and Dr. Tambur are certified by the American College of Histocompatibility and Immunogenetics as laboratory directors and clinical consultants.


The Histocompatibility and Engraftment Monitoring Core currently provides the following services to the investigators of the CTC as well as other investigators in Northwestern University. Investigators will be responsible for the costs incurred for their projects. We offer a verity of high complexity laboratory assays, all performed under strict CLIA guidelines. Consultation regarding clinical interpretation of these assays is also available.

  • HLA typing for Class I and Class II antigens
    • Low/intermediate resolution by SSO Labtype
    • High resolution by Next Generation Sequencing (NGS)
  • HLA Class I and Class II antibody assessment
    • PRA analysis and CPRA calculations
    • Single Antigen Bead (SAB) assays by Luminex
    • Single Antigen High Definition Bead assays by flow cytometry
    • Titration studies for antibody strength assessment
  • T and B Lymphocyte flow cytometric crossmatch
    • Donor-Specific
    • Surrogate crossmatch for Shared Epitope analysis and other investigations
  • Engraftment monitoring with 21 genetic markers using STR analysis

Starting a Project

To discuss starting a transplant-specific project using the services of the Histocompatibility Core of the Comprehensive Transplant Center, please contact our director. We are located on the 11th floor of the Tarry Building, 300 E. Superior St.
