CISH Probes
Description:
BCL2 Split CISH Probe is designed for the qualitative detection of human BCL2 gene at 18q21.33 in formalin-fixed, paraffin-embedded specimens by chromogenic in situ hybridization (CISH).
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 (proximal to the BCL2 breakpoint region), and dinitrophenyl-labeled polynucleotides appear bright red distinct dot-shaped (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.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.
Reagent Provided: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
