The Genetic Resources Core Facility (GRCF) is a Johns Hopkins service center providing research expertise, products, and services for the study of the human genome. At the leading edge of technology, the GRCF provides sophisticated tools and equipment oftentimes not available in the individual research lab. The GRCF includes the Core Store and many Research Services. We strive to streamline services such as sample collection, cell line establishment, cell line authentication, cryogenic storage, DNA isolation, oligo and gene synthesis, methylation testing, both Sanger and next-gen sequencing as well as genotyping from handfuls to millions of variants. The GRCF can also help with project design and custom assay development for DNA based studies. Additionally, the GRCF sponsors various educational programs, product seminars and an annual symposium to bring new GRCF technologies to the attention of the researcher. We encourage investigators planning a study to meet with us to discuss your objectives. In many instances we can propose a range of possible approaches and may be able to point you to particular funding opportunities. We are also happy to write letters of support for grant applications that can demonstrate to reviewers that the resources for your study are available at the university. All services and products provided for the GRCF are for research purposes only. We strive to provide high quality, economical products and services to the Hopkins community and we look forward to your advice and input on how we can improve our services. Feel free to drop us a line.
