Test Tube Liquid Biopsy DNA Preimplantation Genetic Testing PGT Clinical Trials

Product Description: Cell-Free DNA (cfDNA) Collection and Preservation System by Orsin Medical Technology

• 1. Product Description

  ---

   

• Orsin Medical Technology’s Cell-Free DNA (cfDNA) Collection and Preservation System offers a reliable, non-invasive solution for the efficient stabilization and transport of high-quality cfDNA samples. Designed for clinical research, liquid biopsy, and molecular diagnostics, our proprietary technology ensures the integrity of cfDNA from blood samples, minimizing degradation and contamination.

  Key Features:
  ✔ Room-Temperature Stability – Eliminates the need for cold chain transport, reducing costs and logistical challenges.
  ✔ High Yield & Purity – Preserves cfDNA fragments for accurate downstream analysis (NGS, PCR, etc.).
  ✔ Clinically Validated – Optimized for compatibility with major diagnostic platforms.
  ✔ User-Friendly – Simple blood collection and seamless integration into lab workflows.

  Ideal for cancer screening, prenatal testing, and disease monitoring, Orsin’s cfDNA system empowers precision medicine with robust, reproducible results.

  3 . Application

  ---

  1. Oncology & Cancer Management

• Early Cancer Detection – Isolate tumor-derived cfDNA (ctDNA) for multi-cancer screening (e.g., lung, breast, colorectal).

• Minimal Residual Disease (MRD) Monitoring – Track recurrence post-surgery/chemotherapy with high sensitivity.

• Therapy Selection & Resistance – Profile mutations (e.g., EGFR, KRAS) to guide targeted therapies.

• Liquid Biopsy – Alternative to invasive tissue biopsies for metastatic or hard-to-access tumors.

• Compatible Tests: NGS panels, ddPCR, methylation profiling.

  2. Prenatal & Reproductive Health

• Non-Invasive Prenatal Testing (NIPT) – Detect fetal chromosomal abnormalities (e.g., trisomy 21, 18, 13) from maternal blood.

• Preimplantation Genetic Testing (PGT) – Support IVF embryo screening.

• Preeclampsia Risk Assessment – Analyze placental cfDNA for early预警.

• 3. Transplant Medicine

• Organ Rejection Monitoring – Detect donor-derived cfDNA (dd-cfDNA) in transplant recipients (e.g., kidney, heart, liver).

• Graft-versus-Host Disease (GVHD) – Monitor post-hematopoietic stem cell transplantation (HSCT).

• Pathogen Detection – Identify microbial cfDNA in sepsis or occult infections (e.g., TB, CMV).

• Autoimmune Disease Research – Study cfDNA release patterns in lupus, rheumatoid arthritis, etc.

• 5. Neurological & Chronic Diseases

• Neurodegenerative Disorders – Investigate cfDNA biomarkers for Alzheimer’s, Parkinson’s.

• Cardiovascular Risk – Correlate cfDNA levels with myocardial injury or stroke.

• 6. Research & Drug Development
