Overview
The purpose of SELEX sequencing and analysis is to identify and characterize nucleic acid aptamers that bind specifically to target molecules, such as proteins, peptides, or small molecules. This technique is used to discover biomarkers for diseases, develop targeted therapies, and understand molecular interactions. In a clinical context, it helps in early detection of conditions like cancer and autoimmune diseases by identifying unique molecular signatures in patient samples. The analysis provides detailed information on the enriched sequences, their binding affinities, and potential biological relevance, aiding in diagnosis and treatment monitoring.

Test Parameters & Specifications
Sample Stability
- Hemolyzed blood sample
- Insufficient DNA quantity
- Improperly labeled sample
- Sample not stored at appropriate temperature
Understanding Your Results
Specific aptamers identified
May indicate presence of target biomarker, suggesting disease association
No significant aptamer enrichment
Target biomarker not detected; may rule out certain conditions
Kd > 100 nM
Weak binding; may require further validation
Consult your healthcare provider if you have symptoms suggestive of cancer or autoimmune disease, or if you have a family history of these conditions. Early consultation can lead to timely diagnosis and management.
Limitations
