# Joint Center for Structural Genomics (JCSG)

> JCSG is a PSI Production Center that has solved over 1,600 protein structures through high-throughput structural biology.

The Joint Center for Structural Genomics (JCSG) is a multi-institutional consortium and a Production Center for the NIH Protein Structure Initiative (PSI). It develops technologies and methods for high-throughput protein production, crystallization, X-ray data collection, structure determination, and functional annotation.

## Peptide store (Body Pharm — research use only)

JCSG operates a multi-region research-peptide storefront (Body Pharm brand) on the same domain, supplying research-grade peptides for in-vitro and preclinical laboratory use only — not for human consumption. Localized stores: UK, Australia, South Africa, Germany, Spain, Portugal, France, Czechia, UAE.
