Reference standard description
Analytical-grade reference standard. Synthetic 11-amino acid pyroglutamate-capped linear peptide (pGlu-EQLERALNSS) corresponding to the helix B surface of erythropoietin, designed to selectively activate the innate repair receptor (IRR/βcR) without binding to the canonical EPOR homodimer. Suitable for IRR pharmacology assays, neuroprotection pathway research, tissue-protective signaling studies, and EPOR selectivity profiling. Certificate of Analysis available online.
For laboratory research use only. Not for human or animal consumption, therapeutic use, clinical use, diagnostic use, dietary supplementation, dosing, injection, ingestion, or administration of any kind.
