The MLL probe, labelled in green, covers a 200kb region including the MLL (KMT2A) gene. The MLLT4 probe, labelled in red, consists of two clones (187kb and 136kb) that flank the MLLT4 gene.
Translocations involving chromosome 11q23 frequently occur in both acute myeloid leukaemia (AML) and acute lymphoblastic leukaemia (ALL). In most cases, the MLL gene is involved but translocation partners are extremely variable, with 79 direct translocation partners having been molecularly characterised so far.
The most common MLL rearrangement in both AML and ALL involves fusion of the MLL and AFF1 (AF4) genes via a t(4;11)(q21;q23) translocation. Three of the other more common translocations involve the MLLT3 (AF9) gene on chromosome 9, the MLLT1 (ENL) gene on chromosome 19 or the MLLT4 (AF6) gene on chromosome 6:
We now have a range of Research Use Only (RUO) Translocation, Dual Fusion probes to allow specific detection of these MLL rearrangements.

Find certificate of analysis documentation for our CytoCell FISH probes
Our lab has been using a wide range of CytoCell FISH probes for a number of years, and have been increasing this range all the time. The probes have clear bright signals and show good reproducibility. CytoCell provides fast delivery of catalogue probes, and are very responsive when we have any queries or problems with their products.

In our hands, CytoCell FISH probes have proven to be of the highest quality with bright, easy to interpret signals, thus providing confidence in our results. OGT's customer support is outstanding, as their staff are extremely knowledgeable and truly care about their customers and their customers’ needs.

Director of Cytogenetics, Carolinas Pathology Group, USA
I first came across CytoCell FISH probes in a previous lab I worked in and I was struck by the quality of the products. Since this time, I have been recommending and introducing CytoCell probes across all application areas — now they are the primary FISH probes used in our lab. They have an excellent range of products and their ready-to-use reagent format saves considerable time.

We have been working with CytoCell fish probes for two decades because of their excellent clarity and intensity regardless of the size of the probe. It is so clear and simple to detect.

The quality and consistency of CytoCell’s probes means I can trust the results, and my clients get their results in a timely manner.
Dr. Theresa C. Brown
Director, Cytogenetics Laboratory, Hayward Genetics Center, Tulane University School of Medicine, USA
It was very important for us to have more consistent results with our probes — easy-to-read bright signals and a range of vial sizes, which is much more cost-effective.
Janet Cowan, PhD
Director of the Cytogenetics Laboratory, Tufts Medical Center, USA
Not only do CytoCell offer an extensive range of high-quality FISH probes, the customer support is also excellent — providing fast access to all the probes I need. The probes are highly consistent with bright signals allowing easy scoring of results.
Dr. Eric Crawford
Senior Director, Genetics Associates Inc., USA
The quality and reproducibility of results using the CytoCell kit has been vital in accurately detecting co-deletions in our glioma investigations. We now have a cost-effective test that we can rely on that is also easy to use and interpret. We've been consistently impressed with this kit - not to mention the support offered by OGT's customer service, and have completely transitioned over to CytoCell probes.
