About Amino Foundry
Research-grade peptide synthesis for laboratory use. Third-party tested, HPLC verified, endotoxin tested.
What Is Amino Foundry's Research Mission?
Amino Foundry was founded to address a critical gap in the research peptide market: scientific documentation. While many suppliers offer compounds for laboratory research, few provide the molecular detail, published research citations, and methodological transparency that serious research demands.
We are a US-based supplier of research-grade peptides for laboratory use. Every compound in our catalog is accompanied by detailed molecular specifications, amino acid sequences, and citations from peer-reviewed literature. We believe researchers deserve transparency about the compounds they study.
Our focus is on compounds used in published preclinical research, particularly those investigated in cellular and tissue models. We maintain strict compliance with content standards: no human or animal results, no preparation-for-research-use instructions, no usage guidance—only the molecular science and published research literature.
What Quality Standards Does Amino Foundry Apply?
Every compound we supply undergoes rigorous analytical verification before release. Our quality process ensures that researchers receive compounds that match their specifications.
How Does HPLC Verification Work?
High-Performance Liquid Chromatography confirms purity and identity. Each compound is tested to ensure it meets or exceeds the stated purity threshold (typically ≥99%).
What Does Mass Spectrometry Confirm?
LC-MS/MS analysis confirms molecular weight and structural integrity. This analytical technique provides definitive identification of peptide compounds.
What Does Endotoxin Testing Verify?
Limulus Amebocyte Lysate (LAL) testing ensures endotoxin levels meet research-grade standards for cell culture applications.
What Is a Certificate of Analysis?
Each batch receives a Certificate of Analysis (CoA) documenting analytical results, batch numbers, and testing dates.
How Is Amino Foundry's Facility Operated?
Amino Foundry operates from facilities designed for research compound handling and distribution. Our operations include climate-controlled storage areas maintaining -20°C for long-term compound preservation, clean packaging environments, and laboratory-grade weighing equipment.
We partner with third-party analytical laboratories for compound verification. These laboratories are ISO 17025 accredited and operate according to Good Laboratory Practice (GLP) guidelines. Published analytical standards confirm that third-party testing provides independent quality verification free from supplier bias (PMID: 19549937). This separation of synthesis and analytical testing ensures unbiased quality verification.
All operations comply with relevant regulations for research chemical distribution. Our compounds are labeled and sold exclusively for laboratory research use, with appropriate documentation accompanying every shipment.
What Scientific Documentation Does Amino Foundry Provide?
Every product page includes detailed scientific documentation: molecular formula, molecular weight, CAS number, amino acid sequence, receptor targets, and mechanisms of action from published research. We cite peer-reviewed literature with PubMed identifiers (PMIDs) for every scientific claim.
This approach makes Amino Foundry unique among US peptide suppliers. Where competitors provide minimal product information, we provide molecular-level detail that supports serious research applications. Published research demonstrates that analytical documentation including HPLC chromatograms and mass spectra is essential for verifying compound identity and purity prior to experimental use (PMID: 25342275). Our content focuses on the science—the molecular mechanisms, binding affinities, and receptor interactions documented in preclinical literature.
Frequently Asked Questions About Amino Foundry
What purity standards does Amino Foundry apply to research peptides?
Amino Foundry applies a minimum ≥99% purity standard to all research peptides, verified by reverse-phase High-Performance Liquid Chromatography (HPLC) with UV detection at 214 nm. This threshold ensures that fewer than 1% of sample content consists of synthesis-related impurities such as truncated sequences, oxidized variants, or residual reagents. Published research demonstrates that purity at this level is required for reproducible results in receptor binding assays and cell culture studies, where even trace impurities can confound experimental outcomes (PMID: 19549937). Batches failing to meet the ≥99% specification are rejected and not released. Researchers receive the actual purity percentage on the batch-specific Certificate of Analysis, not a generic specification claim. This commitment to documented, measurable purity standards distinguishes Amino Foundry from suppliers who do not disclose analytical methodology or provide batch-specific testing data with every order.
How does Amino Foundry verify peptide identity and purity?
Amino Foundry uses two complementary analytical techniques for every compound: HPLC for purity quantification and LC-MS for molecular identity confirmation. HPLC separates peptide components based on hydrophobicity, generating a chromatogram where purity is calculated as the target peptide peak area divided by total peak area. LC-MS confirms molecular weight through electrospray ionization and mass-to-charge ratio measurement, with observed mass compared against theoretical values within ±0.5 Da tolerance. Both methods are performed by ISO 17025 accredited third-party laboratories independent of the synthesis supplier. Published analytical guidelines establish this dual-method approach as the standard for research peptide characterization (PMID: 25342275). Endotoxin testing using the LAL assay is also performed for compounds intended for cell culture applications. Results from all three tests are compiled into the Certificate of Analysis provided with every batch shipment.
What is the difference between HPLC purity and mass spec confirmation?
HPLC purity and mass spectrometry serve distinct but complementary analytical purposes. HPLC quantifies purity by measuring the proportion of the target compound peak relative to all detected peaks in the chromatogram—it tells you how much of the sample is the intended peptide. Mass spectrometry confirms molecular identity by measuring the mass-to-charge ratio of ionized molecules—it tells you what the compound is. A peptide could theoretically show high HPLC purity but still be the wrong compound if synthesis produced a structurally similar impurity with similar chromatographic retention. Conversely, a peptide could have correct mass but low HPLC purity due to multiple co-eluting variants. Published guidelines emphasize that both tests are required for complete compound characterization (PMID: 19549937). Amino Foundry requires both HPLC and LC-MS results before releasing any batch, and both appear on the Certificate of Analysis with method parameters and acceptance criteria clearly documented.
What documentation does Amino Foundry provide with each research peptide order?
Each research peptide order from Amino Foundry includes a batch-specific Certificate of Analysis (CoA) documenting the complete analytical testing record for that production lot. The CoA contains the compound name, CAS number, molecular formula, molecular weight, and amino acid sequence alongside HPLC purity results with chromatogram, LC-MS identity confirmation with observed versus theoretical mass, and endotoxin test results where applicable. Batch number and testing dates enable full traceability from the vial to the analytical record. Published quality standards establish CoA documentation as the primary mechanism for research compound traceability and experimental reproducibility (PMID: 30915550). Amino Foundry also provides access to product-level scientific documentation including published PMID citations for molecular mechanisms and receptor interactions. Researchers are encouraged to retain CoAs with laboratory records and experimental notebooks, as journals increasingly require analytical characterization of research compounds in supplementary materials.
