Product Introduce
Microsatellite Instability (MSI) Reference Standards
Microsatellite instability (MSI) results from insertion or deletion mutations in short tandem repeats, often caused by deficient mismatch repair (dMMR). MSI is a key biomarker for Lynch syndrome screening and immunotherapy response (e.g., pembrolizumab for MSI-H solid tumors).
CB-Gene’s MSI diagnostic reference standards cover both microsatellite stable (MSS) and MSI-high (MSI-H) statuses, with pre‑characterized instability percentages ranging from 1.92% to 100%. These standards are compatible with PCR‑fragment analysis and NGS platforms, supporting assay development, optimization, and routine quality control.
Product Advantages
our MSI Reference Standards empower laboratories to deliver confident results, advancing personalized oncology and precision diagnostics.
Comprehensive validation
Precisely characterized using gold‑standard methods (PCR fragment analysis and NGS), aligned with FDA/CLIA guidelines.
Multiplex locus coverage
Includes NCI‑recommended loci (BAT25, BAT26, D5S346, D2S123, D17S250) and additional markers (NR‑21, NR‑24, MONO‑27) for enhanced specificity.
Wide instability gradient
MSS (stable) and MSI‑H samples with pre‑determined instability percentages (1.92% – 100%).
Traceability & stability
Manufactured under strict quality controls with batch‑to‑batch consistency and long‑term stability documentation.
Platform flexibility
Compatible with mainstream MSI detection methods: PCR‑capillary electrophoresis and NGS panels.
Ready‑to‑use
Pre‑characterized MSI status and percentage values – no additional bioinformatics required.
