Frequently Asked Questions

What is a PEG linker?

A PEG (polyethylene glycol) linker is a polymer chain used to connect two molecules, often in bioconjugation. It improves solubility, reduces immunogenicity, and increases the circulation half-life of therapeutic molecules.

Can you synthesize custom PEG derivatives?

Yes. RuiaoBio specializes in custom PEG synthesis. We can produce PEGs with specific chain lengths, functional groups (e.g., NHS, maleimide, azide), and protection schemes according to your requirements.

What purity levels do you offer?

We typically provide PEG derivatives with ≥95% purity, with many products exceeding 98%. Analytical data (NMR, HPLC, MS) is available upon request.

Do you provide bulk quantities?

Yes, we support scale-up from research scale (mg) to commercial production (grams to kilograms), depending on the compound.
