How KRAS Services Platform Supports High-Throughput Mutation Screening

The KRAS Services Platform is designed to facilitate high-throughput screening of KRAS mutations, which are among the most common oncogenic drivers in human cancers. By utilizing a broad array of KRAS mutant variants—including G12D, G12C, G12V, G13D, and Q61H—the platform offers researchers access to a comprehensive mutation spectrum. The platform integrates protein purification, SPR (Surface Plasmon Resonance) binding assays, and nucleotide exchange assays to evaluate the interaction of KRAS mutants with key regulatory proteins such as SOS1, SOS2, and cRAF. This multi-faceted approach enables the precise measurement of binding affinities and kinetics, critical for identifying potential inhibitors that can disrupt oncogenic signaling. Additionally, the platform’s cell-based assays, including KRAS Cancer Cell Panels and Ba/F3 cell proliferation assays, provide robust systems to assess the biological impact of compounds on cell viability and proliferation. These capabilities collectively streamline the mutation screening process, allowing for rapid and reliable evaluation of therapeutic candidates.

Best Practices for Combining RAS Assays with KRAS Assay Services

Combining RAS assays with KRAS Assay Services enhances the depth and breadth of oncogenic mutation analysis. Researchers are advised to adopt a tiered approach, beginning with biochemical assays such as nucleotide exchange and protein-protein interaction studies to characterize the molecular mechanisms of KRAS mutants. Using techniques like TR-FRET and HTRF, the platform can detect the inhibition of KRAS binding to exchange factors and downstream effectors, providing valuable insights into the efficacy of small molecules. Following biochemical validation, integrating cell-based assays is essential to evaluate the functional consequences of mutations and drug treatments in a physiological context. The use of diverse cancer cell panels covering multiple cancer types and KRAS mutation variants ensures comprehensive profiling. Moreover, employing both 2D and 3D cell culture formats can reveal distinct cellular responses, enhancing translational relevance. By strategically combining these assays, researchers can generate robust, multi-dimensional data that drive informed decision-making in drug development.

Case Studies Demonstrating the Impact of KRAS Assay Services on Research

Several case studies highlight the transformative impact of KRAS Assay Services on oncology research. For example, the application of SPR binding assays enabled the characterization of the binding kinetics of MRTX1133, a small molecule inhibitor targeting KRAS G12D and G12C mutants. This assay revealed high-affinity interactions that correlated with potent inhibition of downstream signaling pathways. Complementary nucleotide exchange assays using fluorescence-labeled BODIPY-GTP and HTRF methods demonstrated the compound’s ability to block KRAS activation by inhibiting GDP-GTP exchange. Furthermore, cell proliferation assays using Ba/F3 cells and specialized cancer cell panels confirmed the biological efficacy of MRTX1133 in reducing cell viability across multiple KRAS mutant backgrounds. These integrated assay results provided a comprehensive profile of the compound’s mechanism of action and therapeutic potential. Such case studies underscore the value of the KRAS Services Platform in accelerating drug discovery and validating novel therapeutic strategies.
