TP53 OncoKitDX

Background on TP53 and Cancer

The TP53 gene encodes the p53 protein, a transcription factor that plays a central role in maintaining genomic stability. It regulates key cellular processes including DNA repair, cell cycle arrest, apoptosis, and senescence in response to cellular stress and DNA damage. Due to its critical function, TP53 is often referred to as a tumor suppressor gene.

Mutations in TP53 are among the most common genetic alterations observed across a wide range of cancers. These mutations can lead to loss of normal p53 function, resulting in uncontrolled cell proliferation and resistance to apoptosis. TP53 alterations are associated with tumor progression, poor prognosis, and resistance to certain therapies.

In addition to somatic mutations in tumor tissue, germline TP53 mutations are linked to hereditary cancer syndromes such as Li-Fraumeni syndrome. Accurate detection of TP53 variants is therefore essential for research into cancer biology, genomic instability, and genotype-phenotype correlations.

Kit Description

The TP53 OncoKitDx™ is designed for comprehensive detection of TP53 gene alterations using a combination of multiplex PCR and Next-Generation Sequencing. The assay enables high-throughput analysis of multiple genomic regions within a single workflow, providing detailed insight into the TP53 mutation landscape.

The panel covers coding regions as well as splice sites and selected non-coding regions, allowing detection of point mutations, small insertions and deletions, and splice variants. This broad coverage supports accurate characterization of both common and less frequent TP53 alterations.

The kit is compatible with genomic DNA extracted from peripheral blood and formalin-fixed, paraffin-embedded (FFPE) tumor tissue. This enables analysis of both inherited and tumor-specific variants within the same experimental framework.

Workflow and Integration

The assay is designed for integration into standard molecular biology workflows. The use of multiplex PCR reduces the number of reactions required, while NGS enables simultaneous analysis of multiple targets and samples.

This combined approach supports efficient processing and high-throughput analysis, while maintaining reproducibility and consistency across runs. The kit is compatible with commonly used sequencing platforms, facilitating implementation in laboratories with existing NGS infrastructure.

Research Applications

Detection of TP53 mutations is central to cancer research, as these alterations play a key role in tumor development and progression. Identification of TP53 variants supports studies on tumor suppressor gene function, genomic instability, and molecular mechanisms of carcinogenesis.

The assay enables investigation of genotype-phenotype correlations, including the relationship between specific TP53 mutations and clinical outcomes. It also supports research into treatment response and resistance, as TP53 status can influence sensitivity to chemotherapy and targeted therapies.

In addition, the detection of germline TP53 mutations contributes to studies on hereditary cancer syndromes and genetic predisposition. Comprehensive profiling of TP53 variants supports biomarker discovery and the development of precision medicine strategies.

Summary

The TP53 OncoKitDx™ provides a comprehensive, NGS-based solution for the detection of germline and somatic variants in the TP53 gene. Its broad genomic coverage, multiplex PCR design, and compatibility with blood and tumor samples enable detailed and reproducible mutation analysis.

Optimized for integration into molecular workflows, the kit supports high-throughput sequencing while maintaining analytical accuracy. By enabling reliable identification of TP53 alterations, the TP53 OncoKitDx™ supports research into cancer genetics, tumor biology, and the development of targeted therapeutic approaches.
