Research Peptides Testing

Analytical testing for research-use peptides. Our standardized QC panels cover purity, endotoxin, sterility, and heavy metals, delivering verified results in 3 to 5 business days. Whether you need a full QC panel or individual a-la-carte tests, we provide the analytical data your research requires.

Services for Research Peptides

Purity & Quantitation (HPLC)

Reversed-phase HPLC analysis for research peptide purity assessment and active content determination. We report both purity percentage and quantitative content.

Endotoxin Testing (USP <85>)

Kinetic chromogenic LAL method for bacterial endotoxin quantitation. Results reported in EU/mg with full method documentation on the Certificate of Analysis.

Rapid Sterility Screen

DNA-based microarray platform for rapid detection of a broad panel of microbial contaminants. Results available in days, not the traditional 14-day incubation period.

Heavy Metals (ICP-MS)

Multi-element screening for residual metals commonly introduced during solid-phase peptide synthesis, including copper, zinc, iron, and lead.

Full QC Panel

Our most popular option. Bundled testing package covering purity, endotoxin, sterility, and heavy metals in a single submission with preferred pricing and faster turnaround.

Custom Testing

Need something specific? We can develop and validate custom analytical methods for amino acid analysis, sequence confirmation, or other research peptide assays.
