MYC Split CISH Probe is designed for the qualitative detection of human MYC gene at 8q24.21 in formalin-fixed, paraffin-embedded specimens by chromogenic in situ hybridization (CISH).
Recommend Usage:
The product is ready-to-use. No reconstitution, mixing, or dilution is required. Bring probe to room temperature (18-25°C) and mix briefly before use.
Supplied Product:
Reagent Provided:1. Digoxigenin-labeled polynucleotides targeting sequences mapping in 8q24.21* (chr8:130,373,051-130,847,951) distal to the MYC breakpoint region2. Dinitrophenyl-labeled polynucleotides targeting sequences mapping in 8q24.21* (chr8:127,888,765-128,363,281) proximal to the MYC breakpoint region 3. Formamide based hybridization buffer*according to Human Genome Assembly GRCh37/hg19
Storage Instruction:
Store at 2-8°C in an upright position. Return to storage conditions immediately after use.
Note:
The probe is intended to be used in combination with the CISH Implementation Kit 2 (Catalog #: KA5366), which provides necessary reagents for specimen pretreatment and post-hybridization processing.Hybridization signals of digoxigenin-labeled polynucleotides appear dark green distinct dot-shaped (distal to the MYC breakpoint region), and dinitrophenyl-labeled polynucleotides appear bright red distinct dot-shaped (proximal to the MYC breakpoint region).Normal situation: In interphases of normal cells or cells without a translocation involving the MYC gene region, two red/green fusion signals appear.Aberrant situation: One MYC gene region affected by a translocation is indicated by one separate green signal and one separate red signal. Other signal distribution may be observed in some abnormal samples which might result in a different signal pattern than described above, indicating variant rearrangements. Unexpected signal patterns should be further investigated.

Applications
Chromogenic In Situ Hybridization (FFPE Tissue)
Non-Hodgkin lymphoma tissue section with translocation affecting the 8q24.21 locus as indicated by one red/green fusion (non-rearranged) signal, one red signal, and one separate green signal.
Chromogenic In Situ Hybridization (Cells)
Normal interphase cells as indicated by two red/green fusion signals per nucleus.
The protein encoded by this gene is a multifunctional, nuclear phosphoprotein that plays a role in cell cycle progression, apoptosis and cellular transformation. It functions as a transcription factor that regulates transcription of specific target genes. Mutations, overexpression, rearrangement and translocation of this gene have been associated with a variety of hematopoietic tumors, leukemias and lymphomas, including Burkitt lymphoma. There is evidence to show that alternative translation initiations from an upstream, in-frame non-AUG (CUG) and a downstream AUG start site result in the production of two isoforms with distinct N-termini. The synthesis of non-AUG initiated protein is suppressed in Burkitt"s lymphomas, suggesting its importance in the normal function of this gene. [provided by RefSeq
