About GR-E1

GR-E1 is a 37-amino-acid synthetic amylin analogue engineered for selectivity at the amylin 1 receptor over the calcitonin receptor. It is supplied as a lyophilized powder and is used in vitro in amylin-receptor subtype selectivity work.

Every vial is filled and lyophilized under GMP at the source and leaves with a batch number on the label. Purity, identity, net peptide, water, counter-ion and endotoxin are run by an independent ISO/IEC 17025-accredited laboratory in the United States, and the certificate for that lot is published in full.

For research use only Not for human or veterinary use, and not for diagnostic or therapeutic use. Sales are final on opened vials; sealed vials may be returned within 14 days. Orders placed before 2:00 PM ET ship the same business day. Free shipping over $200.
