FAQ

What purity do I need?
For routine PCR, desalting or cartridge may suffice. For qPCR, FISH, or therapeutic development, we recommend HPLC with MS identity for consistent performance and documentation.
Can you support GLP/GMP programs?
Yes. We offer process controls, batch records, and enhanced documentation tailored to GLP or GMP expectations; talk with us about your regulatory pathway.
Do you formulate duplexes or pools?
We can anneal siRNA duplexes with stoichiometry checks and prepare equimolar pools, delivering plate‑ready materials to your specifications.
