The science behind
every vial.

Peptides are short chains of amino acids — the same building blocks as proteins — that act as precise biological messengers. Understanding the science behind them starts with understanding how they're made, measured, and maintained.

Fundamentals

What exactly is a peptide?

Peptides are short chains of amino acids — typically 2 to 50 — linked together by peptide bonds. Structurally, they are smaller than proteins but share the same fundamental building blocks. Because of their compact size, peptides can be synthesized with high precision and cross biological barriers more readily than larger protein molecules.

In research contexts, synthetic peptides allow scientists to study specific biological signaling pathways in isolation — making them invaluable tools for understanding mechanisms of cell communication, receptor activation, and tissue response.

Core Principles

Four pillars of research integrity

Purity

99%+ HPLC Verified

High-Performance Liquid Chromatography (HPLC) is the gold-standard analytical method for quantifying peptide purity. A result of 99%+ means at least 99% of the measured sample is the target compound — with under 1% constituted by synthesis by-products, truncated sequences, or impurities. Every SelaraLabs batch is tested independently before shipment.

Synthesis

SPPS Manufacturing

Our compounds are produced via Solid-Phase Peptide Synthesis (SPPS) — the industry-standard method for constructing peptide chains with precise amino acid sequence control. SPPS allows exceptional reproducibility batch to batch, with each step monitored for coupling efficiency. Post-synthesis, peptides are lyophilized to preserve molecular integrity during storage and transit.

Documentation

COA On Every Batch

A Certificate of Analysis (COA) accompanies every SelaraLabs order. Each COA documents the HPLC purity percentage, molecular weight confirmation via mass spectrometry, synthesis date, and batch identifier. COAs are issued by an independent third-party laboratory — not self-reported. Documentation is available for review upon request.

Research Context

For Research Use Only

All SelaraLabs products are intended exclusively for in vitro research, laboratory investigation, and scientific study. They are not approved by the FDA for human or veterinary use. Purchasers confirm research-only intent at checkout via mandatory attestation. This designation is documented and retained for every transaction.

Storage & Handling

Proper handling for reliable research results

STEP 01

Upon Receipt

Inspect seal and packaging integrity upon arrival. Verify batch ID against the enclosed Certificate of Analysis. Log receipt date in your research records.

STEP 02

Laboratory Storage

Store lyophilized peptide compounds at −20°C in a sealed, moisture-free environment. For short-term lab use (under 48 hours), storage at 4°C is acceptable. Avoid repeated temperature fluctuations.

STEP 03

In-Vitro Preparation

For in-vitro or cell-culture applications, reconstitute using research-grade sterile solvent appropriate to your assay protocol. Prepare only the volume needed per experiment session.

STEP 04

Research Handling

Protect from UV light, oxidizing agents, and repeated agitation. All compounds are supplied strictly for laboratory research use. Not for human or veterinary administration.

Lyophilized peptides are stable at room temperature during transit and short-term storage. Long-term stability: up to 24 months at −20°C. Avoid repeated freeze-thaw cycles in any form.
