Research Cytogenetics Laboratory
Welcome to the OHSU Research Cytogenetics Core Laboratory. We are a fee-for-service cytogentics laboratory available to genetics researchers to assist in development and execution of cytogenetics experiments for research purposes. Through rigorous standardization of protocols and customized experiment development, the OHSU Research Cytogenetics Core Laboratory provides high quality metaphase and interphase cytogenetic data to the OHSU research community. Services are also available to non-profit and commercial investigators located in Oregon and elsewhere.
