TOP2A Amplification Probe

◆TOP2A Gene Amplification Detection Probe

◆Product Advantages

1.Fleetness: Tissue probe hybridization time: 2 hours. Cell probe hybridization time: 1 hour. 

2.Accuracy: Less non-specific background staining (dyeing). Increase difficult samples detection rate. 

3.Reproducibility: Different laboratories test results are highly reproducible. 

◆Probe Description

The TOP2A gene amplification probe is labeled with orange dye for TOP2A gene region, and green dye for chromosome 17 centromere region (CEP17). The TOP2A gene tagged region is located at 17q21.2. The CEP17 probe adopts the α-satellite sequence and has a very high specificity. It does not generate hybrids with other chromosome centromeres.

◆Clinical Significance

Patients with abnormal TOP2A genes are predictive of a shorter relapse-free survival, and patients with TOP2A gene deletion have worse prognosis. The study of advanced breast cancer found that TOP2A gene anomalies are significantly associated with protein expression and tumor cell sensitivity to anthracyclines. Therefore, the detection of TOP2A gene status has guiding significance for the treatment and prognosis of breast cancer.
