GMP Custom Peptide Synthesis

With over 25 years of unparalleled peptide manufacturing experience, AnaSpec is your trusted source of highly complex peptides.  With a focus on excellent customer service, we strive to exceed expectations by investing in ongoing development of proprietary chemistries that deliver only the highest quality peptides.

By extending our long-standing RUO custom peptide expertise to GMP Manufacturing, we combine innovation with GMP grade reproducibility, traceability, and consistency. We provide flexible batch sizes from small scale to large scale manufacturing including synthesis, purification, and lyophilization.

Production of our GMP peptides is performed in a highly controlled environment using qualified equipment and staff. We follow a full set of SOPs and thoroughly document each process in batch records that are archived for 5 years.

AnaSpec’s Quality Management system is ISO 9001 certified and compliant with 21 CFR parts 820 for medical device and IVD components.


We are a trusted peptide manufacturer

All of our GMP peptides follow a stringent QC process. We systematically check the basic peptide properties such as identity, appearance and purity but we also offer a large range of validated QC methods including water content determination, endotoxin and bioburden measurement, solubility testing and residual water or counter-ion content, among others.

A wide range of uses*


Diagnostic companies or Clinical laboratories potentially utilize GMP peptide ASR’s to develop in vitro diagnostic tests for the detection of molecules and analytes in biological samples.

BIOPHARMACEUTICAL manufacturing materials & precursors

GMP peptides synthesized at AnaSpec can be incorporated as starting materials in the production of biopharmaceuticals.

QC CONTROLS & STANDARDS for biopharmaceuticals & API’s

Calibration standards for LC-MS/MS, 2-D electrophoresis for analyzing performance of mass spectrometers and for characterization of proteins.

PRE-CLINICAL animal testing

GMP grade peptides can be incorporated into

pre-clinical animal studies, to facilitate consistency in pharmacokinetic and toxicity studies.
