Who We Are
About Santa Cruz Scientific
An analytical laboratory dedicated to the science of peptides.
Our Mission
Santa Cruz Scientific exists to give peptide manufacturers, researchers, and compounding pharmacies the analytical clarity they need to move forward with confidence. Peptides are powerful but demanding molecules, and a product can only be as good as the data behind it. Our mission is to deliver accurate, reproducible, and clearly documented testing you can build decisions on.
What We Do
We focus on the analyses that matter most for peptide quality and safety: purity by reverse-phase HPLC (with optional LC-MS confirmation), sterility testing following USP <71>, bacterial endotoxin testing by LAL per USP <85>, and heavy metal (elemental impurity) testing by ICP-MS per USP <232>/<233>. By concentrating on peptides rather than spreading across every sample type, we tailor our methods to peptide chemistry and interpret results with real context.
What Drives Our Work
Accuracy
Validated, well-controlled methods and careful technique, so your results reflect reality — not noise.
Transparency
Clear certificates of analysis with the underlying data, so you always understand what was measured and how.
Partnership
Responsive communication and guidance on which tests fit your product and intended use.
Let’s work together
Have a peptide that needs characterization or release testing? We’d be glad to help.
