Genetic Resources Core Facility Biorepository & Cell Center



          GRCF Upcoming Events


Overview of Services

The GRCF Biorepository & Cell Center was established in 1989 as a core resource to produce immortalized cell lines from human blood (EBV transformations). Continued success has enabled the lab to open its doors to the Hopkins community at large and to expand its services to include cryogenic storage in an on-site biorepository, bioprocessing such as mammalian cell culture and blood processing and domestic / international bioshipping. In 2013 the GRCF Biorepository & Cell Center proudly received the international recognition of CAP (the College of American Pathologist) Accreditation. This voluntary program demands that a laboratory go well beyond acceptable quality and regulatory compliance measures to help achieve the highest standards of excellence in our services. Our mission in the GRCF Biorepository & Cell Center is to bring high quality, cost effective services to investigators throughout the Johns Hopkins scientific community.
