Description
Product Description
Cibinetide, also known as ARA 290, is a short synthetic peptide derived from a specific structural region of erythropoietin (EPO). Unlike full-length EPO, Cibinetide does not stimulate erythropoiesis and is primarily studied for its role in non-hematopoietic signaling pathways associated with inflammation regulation and cellular protection.
In experimental research, is commonly used to investigate mechanisms related to immune modulation, neural protection, and tissue response to injury. Its selective interaction with tissue-protective receptor complexes has made Cibinetide a useful model peptide for studying EPO-related signaling without hematologic effects.
This product is provided in lyophilized powder form, supporting long-term stability and consistent handling under controlled laboratory conditions.
