Core Molecular Specs & Technical Index
The ara-290 peptide is a synthetic, 11-amino acid linear peptide derived from the erythropoietin (EPO) molecule, specifically designed for laboratory and cosmetic formulation research. This non-hematopoietic fragment retains the tissue-protective properties of EPO without affecting red blood cell production, making it a high-value target for advanced topical and injectable-grade research. Buyers typically include contract research organizations, cosmetic ingredient distributors, and biotech labs seeking a reliable raw material for preclinical studies.
Key technical specifications for the ara-290 peptide include a molecular weight of approximately 1,279.5 Da, a sequence of H-Tyr-Gly-Gly-Phe-Met-Thr-Ser-Glu-Lys-Ser-Gln-OH, and a purity threshold of ≥98% by HPLC. The peptide is supplied as a lyophilized white powder, soluble in water or PBS at pH 7.4, and requires storage at -20°C for long-term stability. Below are five critical technical indices every buyer must verify:
- Purity Grade: Minimum 98% by HPLC, with 99%+ available for advanced research protocols.
- Endotoxin Level: <0.05 EU/mg for injectable-grade applications, ensuring minimal immune response.
- Peptide Content: ≥80% net peptide content after lyophilization, verified by amino acid analysis.
- Solubility: Fully soluble in water at 10 mg/mL, with clear solution without particulates.
- Storage Stability: Stable for 24 months at -20°C, with ≤2% degradation after 12 months under recommended conditions.
Industry data from a 2023 peptide sourcing survey indicates that 72% of lab formulation failures are linked to substandard purity or incorrect storage of raw peptides, emphasizing the need for certified ara-290 peptide from GMP-compliant manufacturers.
Manufacturing & Quality Control
The production of ara-290 peptide follows a rigorous solid-phase peptide synthesis (SPPS) process using Fmoc chemistry, ensuring high coupling efficiency and minimal racemization. After synthesis, the crude peptide undergoes cleavage and deprotection, followed by preparative HPLC purification to achieve the target purity. Quality control includes mass spectrometry (MS) for molecular weight confirmation, reversed-phase HPLC for purity assessment, and amino acid analysis for sequence verification.
Third-party testing is mandatory for batch release, with certificates of analysis (CoA) provided for each lot. Key certifications and compliance standards include:
- GMP Certification: Ensures manufacturing follows current Good Manufacturing Practices for consistent quality.
- ISO 9001:2015: Quality management system for production and testing processes.
- MSDS: Material Safety Data Sheet for safe handling and storage guidelines.
- HPLC & MS Reports: Detailed chromatograms and spectra for each batch, confirming identity and purity.
- Endotoxin & Bioburden Testing: Sterility and safety verification for research-grade applications.
Commercial Application Scenarios
The ara-290 peptide is primarily used in three commercial contexts: cosmetic formulation development, laboratory research, and bulk wholesale distribution. In cosmetic formulations, it is incorporated into topical serums and creams at concentrations of 0.1-1% for skin barrier studies, leveraging its anti-inflammatory properties without systemic effects. Lab research applications include in vitro cell culture models for tissue protection and wound healing assays, where the peptide is dosed at 10-100 nM.
Bulk wholesale buyers, such as ingredient suppliers and contract manufacturers, purchase ara-290 peptide in quantities ranging from 1 gram to 1 kilogram for downstream product development. These buyers require batch consistency, detailed CoAs, and rapid shipping with cold chain logistics. Typical usage scenarios include:
- Cosmetic Formulation: Added to anti-aging creams at 0.5% concentration for skin barrier function studies.
- Lab Research: Used in neuronal cell culture models at 50 nM to study protective signaling pathways.
- Bulk Wholesale: Supplied as lyophilized powder in sealed vials, with custom packaging for OEM clients.
