Microsatellite Instability (MSI) Dx Analysis Test

Contact us

This kit uses PCR+CE methods to detect nine mononucleotide repeat sites including BAT25, BAT26, NR21, NR24, MONO27, BAT52, BAT56, BAT59, and BAT60 in tumor tissues to guide the diagnosis of colorectal cancer patients, especially treated with immune checkpoint inhibitors like anti-PD-1/PD-L1 antibodies.


• Sensitive: Detection limit as low as 3ng, DNA mutation detection ratio as low as 10%.
• Good Stability:The reference product is verified for 2 consecutive days, multiple instruments, multiple operators, and multiple batches, and the sample test results meet the requirements.
• High Anti-interference:Under the interference of hemoglobin, triglyceride, EDTA anticoagulant, doxorubicin, cyclophosphamide, and gemcitabine hydrochloride, the product performance has no obvious effect.
• Population with a family history of colorectal cancer: Screening and identification of Lynch syndrome
• Patients with stage II colorectal cancer: Medication guidance and assessment of prognosis
• Patients with metastatic colorectal cancer: Assessing the benefit of immunotherapy
• Patients with pan-solid tumors: Mainly gastrointestinal tumors
Analysis of results:
• GeneMapper software from Applied Biosystems,
• GeneMarker software from Softgenetics.
Fast and automatic analysis in GeneMarker software:
• pre-made project and MSI application panel with the MEDx kit,
• automatic labeling of markers and samples,
• automatic pairing of tumor samples with healthy ones,
• automatic report generation.
