Educational resources for the laboratory

Original, research-oriented writing on peptide chemistry, handling and analysis. These articles are educational reference material and are kept deliberately separate from our product listings.

What are research peptides?
A complete primer on peptides: the amide bond that defines them, where peptides end and proteins begin, how research grade material is synthesised and purified, and what the research use only designation actually means in a laboratory setting.

Fundamentals · 5 min read
Understanding lyophilized powders
Why research peptides ship as freeze-dried cakes, what the cake structure tells you, and what a collapsed or shrunken cake means for a lot.

Handling · 7 min read
Reconstitution basics for laboratory work
Diluent selection, concentration arithmetic, and the mechanical habits that separate a clean stock solution from a partially denatured one.

Handling · 6 min read
Storage considerations across the peptide lifecycle
Temperature, light, moisture and container chemistry — the four variables that determine whether a lot still matches its certificate a year later.

Quality · 7 min read
How purity is measured and what a certificate of analysis shows
RP-HPLC, mass spectrometry and endotoxin testing — what each technique establishes, and what a purity percentage does and does not mean.

Receptors and signalling: a short primer for peptide research
GPCRs, receptor tyrosine kinases, agonist terminology and biased signalling — the vocabulary used across compound descriptions in this catalog.

Are research peptides legal to buy online?
How research chemicals are classified in the United States, what 'research use only' actually obliges a buyer to do, and the questions to ask before an institutional purchase.

Procurement · 8 min read
How to evaluate a research peptide supplier
A practical checklist for assessing purity documentation, lot traceability, storage handling and analytical independence before placing an institutional order.

Handling · 5 min read
Bacteriostatic water versus sterile water in the laboratory
What benzyl alcohol actually does in a diluent, when a bacteriostatic diluent is the wrong choice, and how diluent selection interacts with peptide stability.

Handling · 6 min read
Concentration calculations for reconstituted peptides
Working through mass-to-volume arithmetic, molar concentration from labelled strength, and the peptide-content correction that most calculations quietly omit.
Read article
Analysis · 7 min read
HPLC and mass spectrometry: what each test actually proves
Why purity and identity are separate questions, what a chromatogram can and cannot show, and how to read the two analyses together on a certificate.

GLP-1 receptor agonists in metabolic research
How single, dual and triple incretin receptor agonists differ mechanistically, and why half-life engineering rather than receptor affinity distinguishes most current analogs.

Growth hormone secretagogues: GHRH analogs versus ghrelin mimetics
Two distinct receptor systems are routinely grouped under one label. Understanding which is which explains the DAC question, the selectivity differences and the pulsatility literature.

BPC-157: what the research literature describes
Sequence origin, the angiogenic and cytoprotective pathways reported in preclinical models, stability characteristics, and where the evidence base currently stops.

TB-500 and thymosin beta-4: the naming problem and the biology
Why TB-500 and thymosin beta-4 are not interchangeable names, what actin sequestration means mechanistically, and how the two materials differ in the laboratory.

GHK-Cu and copper peptides in dermal research
The copper coordination that defines this class, reported effects on matrix remodelling, and the handling constraints that copper chemistry imposes in the laboratory.

Blends and multi-compound research stacks: design considerations
When co-formulated blends are appropriate, why lot-matching matters in multi-compound work, and the attribution problem that combination designs create.
