Critical Assay Challenge The TarMart Advantage (Technical Spec)
Assaying SOS1-mediated nucleotide exchange High-purity SOS1 catalytic domain (Rem-CDC25) and nucleotide-free KRAS proteins available with strictly controlled activity.
SOS1 vs. SOS2 subfamily counter-screening Homolog panel proteins (recombinant SOS2) verified by mass spectrometry to ensure zero cross-contamination.
Lack of reliable intracellular controls Sequence-verified benchmark antibodies and validated siRNA sets included for phenotypic assay normalization.
False positives in high-throughput screening (HTS) Endotoxin-controlled, high-purity proteins reduce non-specific binding in microplate-based assays.

Global Clinical Landscape & Future Outlook

The race for SOS1 therapeutics is intensifying, with major players shifting focus from monotherapy to rational combination regimens. As first-generation SOS1 inhibitors (such as BI-1701963 and MRTX0902) progress through clinical trials, the next wave of R&D is targeting the circumvention of adaptive resistance in KRAS-mutant solid tumors. By disrupting the SOS1-RAS interaction, these therapies prevent the reactivation of wild-type RAS isoforms (KRAS, HRAS, NRAS) triggered by upstream receptor tyrosine kinase (RTK) feedback loops.
