Probe specification

  • MDM2, 12q15, Red
  • D12Z1, 12p11.1-q11.1, Green

The MDM2 amplification probe consists of a 146kb red probe spanning the MDM2 gene and neighbouring CPM gene, with a green centromeric probe for chromosome 12 provided as a control.


Probe information

The MDM2 gene, located at 12q15, when overexpressed, enhances the tumourigenic potential of cells.

The oncogene product forms a tight complex with the p53 tumour suppressor protein and can inhibit p53 mediated transactivation, leading to escape from p53 regulated growth control1. The Murine Double Minute 2 (MDM2) gene has been shown to be amplified in around 7% of human tumours2.

Many tumours overexpress MDM2, the most common being soft tissue tumours (20%), osteosarcomas (16%) and oesophageal carcinomas (13%)3. The use of FISH in well differentiated liposarcoma has been a valuable diagnostic tool4,5, whilst small-molecule MDM2 inhibitors that could act as innovative therapeutic tools have also been identified6.

FFPE tissue preparation and FISH protocol

Select a protocol step to view:

Heat pretreatment

1. Heat Pretreatment Dark Blue
  • Heat 50ml Tissue Pretreatment Solution (Reagent 1) in a porcelain wash jar or coplin jar immersed in a waterbath until it is either boiling or 98 - 100°C.
  • Boil slides for 30 minutes (Note: different incubation times may be required depending on tissue fixation. A 30-minute incubation is a recommended starting point).
  • Wash in PBS or dH2O at room temperature (RT) for 2 x 3 minutes.
