The UroVysion Bladder Cancer Kit probes are directly labeled with one of the Vysis fluorophores; SpectrumRed, SpectrumGreen, SpectrumAqua or SpectrumGold. The UroVysion Bladder Cancer Kit consists of three alpha-satellite repeat sequence probes; CEP 3 SpectrumRed, CEP 7 SpectrumGreen, and CEP 17 SpectrumAqua that hybridize to the centromere regions of chromosomes 3, 7, and 17, respectively. In addition, a unique sequence probe, LSI p16 (9p21) SpectrumGold, is included that hybridizes to the p16 gene at 9p21. This probe set is premixed in Hybridization Buffer.

Results of Hybridization
Determination of results is conducted by enumeration of CEP 3, 7 and 17, and LSI p16 (9p21) signals through microscopic examination of the nucleus.Hybridization is viewed using a fluorescence microscope equipped with appropriate excitation and emission filters allowing visualization of the red, green, aqua, and gold fluorescent signals. Samples hybridized with the UroVysion Bladder Cancer Kit will exhibit signals indicative of the copy number of chromosomes 3, 7, and 17 and of the p16 gene. Processing The UroVysion Bladder Cancer Kit can be used with the Vysis VP2000TM TM Processor for specimen pretreatment and the HYBriteTM Denaturation/ Hybridization unit for modular automation.Vysis Microscope Filter Recommendations
UroVysion probe signals and DAPI counterstain should be viewed with the following Vysis filter sets:
- DAPI single bandpass (DAPI counterstain)
- Aqua single bandpass (chromosome 17)
- Yellow single bandpass (p16 gene)
- Red/Green dual bandpass (chromosomes 3 and 7)
An epi-fluorescence microscope equipped with a 100-watt mercury lamp is strongly recommended.An epi-fluorescence microscope enables a light source to transmit light through the viewing path, replacing the illuminator and condenser of the conventional wide field microscope. For this mode to function, the structures of interest are labeled with a fluorophore. Light from the source is collimated and directed into the tube of the microscope to a 45-degree mirror with an interference coating that lets in light at particular wavelengths and is transparent at other wavelengths (a dichroic mirror). This light is directed to the back of the objective and is focused into the sample. The objective functions as a condenser. Exciting light is absorbed by the fluorophore in the sample. The energy of the absorbed photon causes an electron in the dye molecule to jump to a higher energy orbital state. The electron rapidly jumps back to its ground orbital state, with the energy released becoming a photon of less energy compared to the exciting photon. The emitted photon has a color shifted toward red. The eyepiece collects the image in an identical manner as is transmitted in wide field microscopy.
