GRCF Upcoming Events
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. 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.
We are a part of Johns Hopkins Genomics and function as three units: the Core Store, the Cell Center & Biorepository and DNA Services. This site is for ordering some of the services offered by the DNA Services unit. Other services, including next-gen sequencing, may be ordered on our Genesifter server. The Cell Center & Biorepository and the Core Store maintain separate ordering sites.
