• Mouse Cytogenetics Core

    Chromosome karyotyping and molecular cytogenetics analyses play an important role in the study of chromosome abnormalities, genetic aberrations, cell line characterization and establishing disease models.

    The Mouse Cytogenetics Core at the Cincinnati Children’s Division of Human Genetics offers research investigators support for mouse classic karyotyping and molecular cytogenetic studies. Services include chromosome analysis of mouse tissues and cell lines, karyotype characterization of embryonic stem cells and induced pluripotent stem cells (iPSC), and locus copy number enumeration, refining chromosome breakage sites, and mapping of transgene integration sites.

    Techniques available at the Mouse Cytogenetics Core include:

    Classical Cytogenetic Analyses

    • Short-term cell culture / chromosome harvest
    • Metaphase chromosome preparations
    • G-banded karyotyping
    • Breakage study

    Fluorescence In Situ Hybridization (FISH)

    • Interphase FISH
    • Metaphase FISH
    • FISH on paraffin-embedded tissues
    • Multicolor FISH (M-FISH)
    • Custom FISH probe development (BAC / PAC clone acquisition, BAC / PAC DNA isolation, nick translation / DNA labeling reaction)

    Custom FISH Probe Development

    • Complete FISH probe development (BAC / PAC clone acquisition, culture, DNA extraction, labeling and validation)
    • BAC / PAC Clone Prep*
    • DNA probe labeling / nick translation and validation**
    • BAC and PAC clone purchase


    • Study failure
    • Rush order
    • Specialized assay development

    *Each BAC / PAC DNA preparations may yield 10-15 ug DNA.
    **Each labeling reaction may be good for 7-10 FISH assays.

    Mouse Stem Cells (ES or iPS)

    A minimum of two wells on a 24-well plate per clone, and it is preferable to have 3-4 wells plated at varying densities. The clones need to be 50-80% confluent and require media change the night before submission.

    Mouse Tissue (Fibroblasts)

    Fresh skin (ear, tail), fresh lung, or embryo (mouse embryonic fibroblasts)

    Minimum sample sizes: 6 mm ear, 1 cm tail clip, ½ lobe of lung, early passage fibroblast culture.

    Tissue is collected and sent to the laboratory in sterile transport media at room temperature. Sample must be received with a completed requisition form. Tissues can be stored (refrigerated in transport media for 24 hours), but should be set up fresh when possible. Transport media available upon request.

    For other sample types, please contact us for instruction.
