The IGH/cMYC Plus product consists of probes, labelled in green, proximal to the Constant, and within the Variable segment of the IGH region, and cMYC probes, labelled in red. The cMYC probe mix contains a 220kb probe centromeric to the cMYC (MYC) gene and a second probe covering the 186kb region telomeric to the cMYC gene, including the D8S1644 marker.
The t(8;14)(q24;q32) translocation involving the IGH (immunoglobulin heavy locus) gene at 14q32.33 and the MYC (MYC proto-oncogene, bHLH transcription factor) oncogene at 8q24 is a recognised recurrent abnormality commonly seen in patients with B-cell malignancy.
IGH-MYC rearrangements are detected in up to 85% of cases of Burkitt lymphoma at diagnosis1. They are also seen in diffuse large B-cell lymphoma (DLBCL)2, multiple myeloma and plasmablastic lymphoma3,4.
In an IGH-MYC rearrangement the translocation breakpoints on chromosome 14 are clustered to a narrow region 5' to the intron enhancer of the immunoglobulin heavy chain, whereas the breakpoints on chromosome 8 can occur more than 340kb upstream of MYC, with no preferential site5. The translocation brings MYC into close proximity to the IGH enhancer and results in the up-regulation of MYC. Over-expression of the transcription factor stimulates gene amplification, resulting in uncontrolled cell proliferation6.

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.
Jennie Thurston
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.
