General description
The ZytoLight® SPEC NR4A3 Dual Color Break Apart Probe (PL102) is a direct-labeled FISH probe for the qualitative detection of translocations of the NR4A3 gene at 9q22.33-q31.1 in formalin-fixed, paraffin-embedded specimens using fluorescence in situ hybridization (FISH). The probe is intended for use with the ZytoLight FISH-Tissue Implementation Kit.
ZytoLight® probes enable the precise identification of genetic abnormalities, including translocations, deletions, amplifications, and chromosomal aneuploidies, in formalin-fixed, paraffin-embedded (FFPE) tissue sections or cytology specimens, without the need for additional antibody-based detection.
Components
The ZytoLight SPEC NR4A3 Dual Color Break Apart Probe comprises:
Principle
The fluorescence in situ hybridization (FISH) method enables the identification and visualization of particular nucleic acid sequences within cell samples. DNA fragments labeled with fluorescent dyes, known as FISH probes, are co-denatured with their complementary target DNA strands in the sample and then allowed to hybridize. Following hybridization, non-specific and unbound probe fragments are removed through stringency washes. The DNA is then counterstained with DAPI, and the hybridized probes are detected using a fluorescence microscope equipped with filters matched to the specific fluorochromes used to label the FISH probes.

Components
The ZytoLight SPEC NR4A3 Dual Color Break Apart Probe comprises:
- ZyGreen (excitation 503 nm/emission 528 nm) labeled polynucleotides (~10 ng/µl), targeting sequences mapping in 9q22.33* (chr9:102,070,916-102,561,593) proximal to the NR4A3 breakpoint region;
- ZyOrange (excitation 547 nm/emission 572 nm) labeled polynucleotides (~4.5 ng/µl), targeting sequences mapping in 9q31.1* (chr9:102,636,487-103,065,504) distal to the NR4A3 breakpoint region;
- Formamide based hybridization buffer

Application
This probe is intended for use in formalin-fixed, paraffin-embedded specimens to qualitatively detect translocations of the NR4A3 gene at 9q22.33-q31.1, via FISH.
Analysis Note
Using suitable filter sets, the probe hybridization signals appear green near the NR4A3 breakpoint region and orange away from it.
- Normal scenario: in normal cells during interphase or cells without an NR4A3 gene region translocation, two green/orange fusion signals are observed.
- Aberrant scenario: one translocated NR4A3 gene region is shown by one separate green and orange signal each.
