Questions, answered
1. What are AURAxx and ALPHAxy?
AURAxx and ALPHAxy are suppliers of premium Research Use Only (RUO) peptides built on a simple premise: female and male biology are distinct, and those differences continue to drive meaningful scientific discovery. Our curated RUO peptide collections are designed to support laboratory research exploring those biological distinctions, with an unwavering commitment to analytical quality, batch consistency, and scientific transparency. All products are intended exclusively for legitimate laboratory and in vitro research. They are not intended for human or veterinary use, therapeutic or diagnostic application, or clinical procedures of any kind.
2. What does Research Use Only (RUO) mean?
Research Use Only means our products are intended solely for laboratory research and scientific investigation. They are not intended for human consumption, veterinary use, therapeutic use, diagnostic use, or clinical applications of any kind. This designation governs every aspect of how our products are developed, documented, distributed, and supported.
3. Who can purchase AURAxx and ALPHAxy products?
Our products are intended exclusively for qualified researchers, laboratories, universities, educational institutions, biotechnology companies, and other organizations engaged in lawful scientific, analytical, or in vitro research. By placing an order, the purchaser represents and warrants that the products are being acquired solely for legitimate RUO purposes and will be handled by individuals with the appropriate knowledge and experience to work with laboratory research materials.
Purchasers must be 21 years of age or older and are solely responsible for ensuring that their purchase, possession, handling, storage, transportation, and use of any product complies with all applicable federal, state, and local laws, regulations, and institutional policies.
AURAxx and ALPHAxy reserve the right to refuse or cancel any order that appears inconsistent with the intended Research Use Only purpose of our products.
4. Are your products tested?
Yes. Consistent with the AURAxx Quality Standard, our products undergo analytical evaluation using established laboratory techniques to verify identity and purity. Depending on the product and manufacturing process, testing may include High-Performance Liquid Chromatography (HPLC), Mass Spectrometry (MS), and additional methodologies appropriate to a comprehensive quality assessment. These evaluations help verify that each batch conforms to established product specifications.
5. Are your products manufactured under established quality standards?
Yes. AURAxx and ALPHAxy source RUO materials from manufacturing partners that employ established quality systems, documented manufacturing procedures, and analytical quality control processes appropriate for laboratory research materials. Our supplier qualification philosophy prioritizes:
Documented manufacturing and quality
control procedures
Batch-to-batch consistency
Analytical verification of product identity and purity
Established laboratory testing methodologies
Lot traceability and production documentation
Comprehensive analytical records
Continuous quality monitoring and review
Following manufacturing, products may undergo additional independent analytical evaluation using HPLC and MS where appropriate, consistent with the AURAxx Quality Standard. Findings are captured in batch-specific COAs and provided to researchers whenever applicable.
All products are supplied exclusively as Research Use Only (RUO) materials.
Five Verifications. Every Vial.
Each check is completed before release, documented on the batch Certificate of Analysis, and accessible through your account.
Purity
Reverse-phase HPLC separates the target peptide from truncated sequences and deletion fragments. The chromatogram is recorded and archived in the batch file.
Identity
Mass spectrometry confirms the measured molecular weight matches the target sequence before any vial is released.
Potency
Net peptide content is measured to verify that the milligram quantity stated on the label reflects what is actually in the vial.
Stability
Compounds are lyophilized for long-term shelf stability and shipped under cold-chain conditions to protect integrity from synthesis through delivery.
Endotoxin screening
Each batch is screened for endotoxin levels to a documented threshold, with results recorded on the Certificate of Analysis.
