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. Bioinformatics support for sequencing projects is also available. The GRCF can help with project design and custom assay development for DNA and RNA based studies.
We are a part of Johns Hopkins Genomics and function as three groups: the Core Store, the Cell Center & BioBank and DNA Services. The DNA Services group encompasses the DNA Analysis Facility, the Nucleic Acid Technogies group, the High Throughput Sequencing group and the Bioinformatics group. This site is for ordering most of the services offered by the DNA Services unit. Sanger Seqeuncing and next-gen sequencing, may be ordered on our Genesifter server. The Cell Center & Biorepository and the Core Store maintain separate ordering sites.
