BCL2 Split CISH Probe is designed for the qualitative detection of translocations involving the human BCL2 gene at 18q21.33 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:This Probe is composed of:1. Digoxigenin-labeled polynucleotides, which target sequences mapping in 18q21.33* (chr18:60,610,473-60,779,138) proximal to the BCL2 breakpoint region.2. Dinitrophenyl-labeled polynucleotides, which target sequences mapping in 18q21.33* (chr18:61,134,665-61,507,691) distal to the BCL2 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.Interpretation of results:Using the CISH Implementation Kit 2 (Cat # KA5366), hybridization signals of Digoxigenin-labeled polynucleotides appear as dark green colored distinct dots (proximal to the BCL2 breakpoint region), and Dinitrophenyl-labeled polynucleotides appear as bright red colored distinct dots (distal to the BCL2 breakpoint region).Normal situation: In interphases of normal cells or cells without a translocation involving the BCL2 gene region, two red/green fusion signals appear.Aberrant situation: One BCL2 gene region affected by a translocation is indicated by one separate green signal and one separate red signal.Overlapping signals may appear as brown signals. Genomic aberrations due to small deletions, duplications or inversions might result in inconspicuous signal patterns. Other signal patterns than those described above may be observed in some abnormal samples. These unexpected signal patterns should be further investigated.

Gene Summary:
This gene encodes an integral outer mitochondrial membrane protein that blocks the apoptotic death of some cells such as lymphocytes. Constitutive expression of BCL2, such as in the case of translocation of BCL2 to Ig heavy chain locus, is thought to be the cause of follicular lymphoma. Two transcript variants, produced by alternate splicing, differ in their C-terminal ends. [provided by RefSeq
