Abnova™ ERBB2 CISH Probe

ERBB2 CISH Probe is designed for the qualitative detection of human ERBB2 gene in formalin-fixed, paraffin-embedded specimens by chromogenic in situ hybridization (CISH).

Supplier:  Abnova™ CG0018

Catalog No. 89-335-565

Description

The probe is intended to be used in combination with the CISH Implementation Kit 1, which provides necessary reagents for specimen pretreatment and post-hybridization processing.

Hybridization signals of digoxigenin-labeled polynucleotides appear as brown- to dark brown colored distinct dots (ERBB2 gene region).
Normal situation: In interphases of normal cells or cells without an amplification involving the ERBB2 gene locus, two distinct dot-shaped brown signals per nuclei appear.
Aberrant situation: In a cell with amplification of the ERBB2 gene locus or polysomy of chromosome 17, multiple copies of the brown signal or brown signal clusters will be observed. 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.
