Quraxia provides end-to-end aptamer synthesis services—from design and characterization to biological testing.
What are aptamers?
Aptamers are short DNA or RNA strands that fold into unique 3D structures and bind to molecules, proteins, or cells with very high precision—like antibodies, but with unique advantages:
Can be synthesized quickly and in bulk
Remain stable in storage without losing activity
Cause minimal immune response in therapeutic use
Our Services
Custom synthesis of DNA/RNA aptamers at multiple scales (nanograms to grams)
Modified aptamers (e.g., fluorophore-labeled, thiol/amino modifications, spacers, PEGylation)
GMP-grade and research-grade oligos
Applications
Diagnostics & Biosensors: next-gen test strips, electrochemical & fluorescence sensors
Therapeutics: aptamer-drug conjugates, siRNA delivery, VEGF-targeting aptamers
Imaging: radiolabeled aptamers for PET/SPECT tumor visualization
Research Tools: affinity purification, protein/nucleic acid structural analysis
We make Aptamer delivery customized, reliable, and scalable for both research and clinical needs.
