Description
ARA-290, also known as Cibinetide, is a synthetic 11-residue peptide derived from a surface region of erythropoietin and supplied for controlled laboratory, analytical, and scientific research. Its N-terminal residue is pyroglutamate (pGlu), which is an important part of its molecular identity.
The commonly referenced parent peptide has the molecular formula C₅₁H₈₄N₁₆O₂₁ and an average molecular weight of approximately 1257.3 g/mol.
For accurate technical documentation, the exact terminal state, salt or counter-ion form, purity specification, and lot-specific analytical profile should be confirmed using the applicable Certificate of Analysis.
Research Applications
ARA-290 may be examined in controlled non-clinical research involving:
Peptide identity and characterization
Ligand-receptor interaction studies
Structure-function analysis
Molecular signaling research
Modified-residue characterization
Comparative peptide analysis
Stability assessment
Non-clinical biochemical and cellular models
Experimental observations should remain specific to the applicable research system and should not be interpreted as evidence of neurological, tissue-protective, anti-inflammatory, therapeutic, or clinical effectiveness.
Structural Information
ARA-290 is commonly represented as:
pGlu-Glu-Gln-Leu-Glu-Arg-Ala-Leu-Asn-Ser-Ser
The peptide contains 11 residues, with an N-terminal pyroglutamate modification and a free C-terminal carboxyl group.
Key structural characteristics include:
11-residue peptide chain
N-terminal pyroglutamate
Defined linear peptide sequence
Free C-terminal carboxyl group
Erythropoietin-derived helix-surface sequence
Because pyroglutamate is a non-standard residue, a conventional one-letter amino-acid sequence does not fully represent the molecular structure.
Analytical Identification
Relevant analytical characterization may include:
Amino-acid sequence confirmation
Pyroglutamate verification
Molecular mass assessment
Chromatographic purity testing
Peptide identity verification
Terminal-state confirmation
Structural characterization
Lot-specific quality analysis
