How Peptides Are Used in Modern Laboratory Studies

Peptides are among the most versatile compounds available to biochemical researchers. These short amino acid chains can act as hormones, messengers, or enzyme substrates, giving scientists direct access to key molecular mechanisms within cells. At Permagainz, our laboratory-grade peptide range includes Follistatin 344, Epitalon, Tesamorelin, and PEG-MGF, each supplied at ≥98 % purity for research applications.

In-Vitro Applications

Within controlled environments, peptides allow researchers to:

• Observe protein folding and structure–function relationships
• Study cell receptor interactions
• Model gene transcription and peptide degradation

For example, Follistatin 344 is frequently used in research involving myostatin inhibition and muscle cell cultures, while Epitalon and N-Acetyl Epitalon Amidate are used to study telomerase activation and peptide stability.
Because peptides can target specific signalling pathways, they have become indispensable in pharmacological discovery and molecular biology.

Laboratory Handling and Storage

Every peptide is supplied as a lyophilised (freeze-dried) powder, which must be stored between 2–8 °C and reconstituted using sterile bacteriostatic water. These materials require professional handling within accredited facilities, following standard biosafety procedures.

All Permagainz peptides are intended solely for scientific and in-vitro research. They are not for human or veterinary administration and must never be ingested, injected, or used therapeutically.

Quality and Compliance

At Permagainz, quality assurance is fundamental. Our peptides are tested by HPLC, mass spectrometry, and amino acid analysis to ensure consistency. Each vial includes a batch code, expiry date, and Certificate of Analysis.

By maintaining full MHRA and REACH compliance, we ensure every compound we distribute meets UK safety and transparency requirements. Researchers can focus on results, knowing that every peptide supplied by Permagainz meets laboratory-grade standards for reliability and purity.
