Custom synthesis

We source and screen custom sequences for institutional clients. Include the sequence in single-letter or three-letter code, required purity, quantity, any modifications (amidation, acetylation, cyclization, labels) and your timeline. Typical lead time is three to five weeks depending on length and complexity.

Institutional accounts

Purchase orders, net terms, consolidated invoicing and volume pricing for universities, contract research organizations and laboratories. Send your institution name, purchasing contact and expected annual volume to get set up.

The scope we can answer within. Caliper supplies reference standards for analytical laboratory testing. Questions on purity, identity, stability, solubility, storage, and reconciling your own analytical data against the certificate are exactly what our team is for. Anything outside analytical laboratory testing falls outside our scope.
