Children's Hospital of Pittsburgh Histocompatibility Center Microfabricated CE Chips to Make More Cost- Effective HLA Class I and Class II Molecular Typing
Abstract
The activities of the Children's Hospital of Pittsburgh Histocompatibility Center can be classified under three major categories: (1) the repository service; (2) the molecular typing service; and (3) the research activities aimed at improving the technical support on which the previous two services are working. This year in the Repository, where blood samples from volunteers as hone marrow donors are collected from more than 125 recruiting centers nationwide, 161,019 samples were processed. We stored 483,057 vials in three sets of freezers (one sample per donor each freezer), while 247,991 were sent out to other Typing Laboratories for molecular HLA typings. In our laboratories, 10,723 typings were performed with a very high Q.C. standard, as monitored by National Marrow Donor Program. Our Center's research branch synthesized all the oligonucleotides to be used as PCR primers or labelled probes to perform molecular HLA typing. DNA sequencing was also performed when hybridization results were not optimal. Alternatives for storing blood samples (e.g., blood spots on filter paper) or for enhancing typing capabilities (e.g., microchip technology to expedite PCR procedures) were successfully implemented or improved to the point of justifying their future implementation.
