Cytogenetics Core services available include:
The Cytogenetics Core Laboratory has experience with all commercially-available probes (e.g., chromosome enumeration probes, painting probes, single copy or locus-specific probes, translocation probes, human and mouse SKY probes, etc.) and nick-translated DNA fragments provided by researchers as “homebrew” probes (nick translocation labeling may be performed by Cytogenetics Core lab personnel). The DNA fragments may be genomic DNA, cDNA or vector DNA; however, due to sensitivity limitations of our current instrumentation, unique sequence probes larger than 2.5 kb are required for mapping studies. If the probe is known to be amplified, probes larger than 1 kb may be used.
The Cytogenetics Core Laboratory is equipped with high-resolution fluorescent and light photomicroscopes, and three computerized imaging systems (including the SKY Applied Spectral Imaging System and the Bioview System), which are able to capture, process and print microscopic images. Tissue culture facilities and equipment for probe labeling and hybridization are also available.
Fluorochromes commonly used with our fluorescent microscopes:
The fluorescent microscopes in the Cytogenetics Core are optimized for observation of the fluorochromes listed below. However, fluorochromes with similar excitation and emission wavelengths as those listed below may also be observed with our systems.
