Eliminating Variables in
Biochemical Research
In experimental design, reagent consistency is the bedrock of reproducibility. RegenPep mitigates the “batch effect” phenomenon by enforcing a stringent dual-verification protocol. We do not simply warehouse peptides; we validate their molecular integrity before they enter the cold chain.
High-Performance Liquid Chromatography (HPLC)
HPLC is employed to separate, identify, and quantify each component in the lyophilized mixture. This technique is critical for detecting synthesis byproducts such as deletion sequences (missing amino acids) or incomplete deprotection species that could interfere with receptor binding affinity.
- Detection of truncated analogs
- Quantification of main peak purity (Target: ≥99%)
- Verification of salt counter-ion removal
Mass Spectrometry (MS)
While HPLC confirms purity, Mass Spectrometry confirms identity. By measuring the mass-to-charge ratio of ions, we verify that the molecular weight corresponds exactly to the theoretical mass of the specific amino acid sequence, ensuring no “scrambled” sequences exist.
- Precise molecular weight validation
- Identification of post-translational modifications
- Confirmation of sequence integrity
Scientific Reference Context
For detailed definitions of these analytical methods, we recommend reviewing established chemical literature. External sources help clarify standard industry terminology used in our COAs.

Lyophilization
A freeze-drying process where water is removed from a frozen sample by sublimation under vacuum. This creates a stable peptide “cake” structure, preserving bioactivity and extending shelf life significantly compared to peptides in solution.
Peptide Bond
The chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is the primary linkage in all protein structures.
Net Peptide Content
Distinct from purity. Purity measures the target peptide vs. impurities (via HPLC). Net Peptide Content measures the weight of the peptide vs. the total weight of the powder (which includes counter-ions and residual water).
Reconstitution
The process of restoring a lyophilized peptide to a liquid state. Researchers typically use bacteriostatic water or sterile saline. Care must be taken to add solvent slowly down the vial wall to avoid damaging the peptide structure.
TFA Removal
Trifluoroacetic acid (TFA) is often used in peptide synthesis. For sensitive cell culture assays, RegenPep ensures TFA salts are exchanged (usually for Acetate or Hydrochloride) to prevent cytotoxicity.
