Abnova™ EWSR1 Split CISH Probe

EWSR1 Split CISH Probe is designed for the qualitative detection of translocations involving the human EWSR1 gene at 22q12.2 in formalin-fixed, paraffin-embedded specimens by chromogenic in situ hybridization (CISH).

Supplier:  Abnova™ CS0008

Catalog No. 89-335-543

Description

The probe is intended to be used in combination with the CISH Implementation Kit 2, which provides necessary reagents for specimen pretreatment and post-hybridization processing.

Hybridization signals of digoxigenin-labeled polynucleotides appear dark green (distal to the EWSR1 breakpoint region), and dinitrophenyl-labeled polynucleotides appear bright red (proximal to the EWSR1 breakpoint region).
Normal situation: In interphases of normal cells or cells without a translocation involving the EWSR1 gene region, two red/green fusion signals appear.
Aberrant situation: One EWSR1 gene region affected by a translocation is indicated by one separate distinct dot-shaped green signal and one separate distinct dot-shaped red signal. Genomic aberrations due to small deletions, duplications or inversions might result in inconspicuous signal patterns. 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.
