Below are some commonly asked questions and resources.
Understanding Peptides: Structure, Discovery, and Innovation
Peptides are chemical compounds found in all living things, formed by two or more amino acids joined by a strong, covalent peptide bond. This crucial bond (also called an amide bond) is created through a condensation reaction: the carboxyl (C-terminus) group of one amino acid links with the amino (N-terminus) group of another, resulting in a CO-NH structure and the release of water.
From their etymological root in the Greek word for “to digest” (pépein), peptides have become recognized as vital components of biochemistry. The natural world teems with thousands of peptides in humans and animals. Constant laboratory discovery and synthesis of new peptides continue to fuel excitement, promising significant advancements in both the health and pharmaceutical sectors.
Research peptides are simply any peptides utilized for scientific investigation, study, and experimentation.
In recent years, peptides have gained significant attention for their potential in therapeutic applications. They’re recognized for being highly selective and effective, yet relatively safe and well-tolerated by subjects. This promising profile has led to a major increase in interest and demand for peptides within pharmaceutical research and development (R&D).
The surging interest necessitates more intense study and experimentation to unlock peptides’ full potential for current and future medical applications and therapeutics. This rising demand drives the need for high-quality research peptides to fuel progress in these new avenues of R&D.
The term in-vitro (Latin for “in glass”) means these studies are performed outside of a living body. Scientists use research peptides in the lab to explore new designs and variants, pushing the boundaries to discover future pharmaceuticals. This work is critical:
Examples include Lupron for prostate cancer and Victoza for type 2 diabetes, both achieving billions in sales.
It’s essential to recognize the difference between a research peptide and an FDA-approved drug:
A research peptide can only become a medicine after it undergoes rigorous study, clinical trials, and, crucially, the formal FDA approval process.
Peptides are broadly categorized based on their method of synthesis, primarily dividing them into ribosomal and nonribosomal types.
Ribosomal peptides are created when mRNA is translated by the ribosome. Functioning widely as hormones and signaling molecules (like vasoactive intestinal peptides), these compounds often undergo further processing via proteolysis (protein breakdown) to achieve their final, mature structure. This class also includes certain antibiotics, such as microcins.
In contrast, nonribosomal peptides are synthesized by dedicated peptide-specific enzymes, bypassing the ribosome entirely. A key structural difference is that nonribosomal peptides are often cyclic and can have complex structures, though linear forms also exist. They are commonly found in fungi and plants. Glutathione, a crucial antioxidant, is the most abundant nonribosomal peptide.
Other functional classes include:
At Pepformance, we deliver peptides with a purity exceeding 99%. We use state-of-the-art solid and solution phase peptide synthetic technology to offer the highest quality peptides and proteins for all research and application needs. This exceptional purity is confirmed through strict manufacturing processes, rigorous quality control, and the critical implementation of both High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) analysis.
HPLC is an advanced technique used to separate, identify, and measure the individual components within a mixture, allowing for highly accurate peptide testing. Mass spectrometry (MS) measures the mass of ionized chemical species in a sample, sorting them by their mass-to-charge ratio. By plotting the resulting ion signal, MS helps confirm the sample’s identity. Both HPLC and MS are highly precise methods that scientifically confirm the identity and purity of all peptides ordered from Pepformance.
Pepformance takes immense pride in product quality, implementing continuous testing throughout the production process to verify the sequential fingerprints of our peptides for maximum accuracy in every preparation.
Proper storage of peptides is crucial for maintaining the integrity of experimental results. Correct practices prevent contamination, oxidation, and degradation, which can render peptides (and therefore experiments) useless. Implementing these guidelines will significantly extend a peptide’s stability regardless of its composition.
Once peptides are received, they must be stored cold and protected from light. Storage duration determines the ideal temperature:
Crucial Freezing Precautions:
It’s vital to protect peptides from air and moisture, especially when working with cold samples:
Peptides stored in solution have a much shorter shelf life and are vulnerable to bacterial degradation. Sequences containing Cys, Met, Trp, Asp, Gln, and N-terminal Glu are notably unstable in solution.
Storage containers must be clean, structurally sound, chemically resistant, and appropriately sized for the peptide volume.
Peptides can be transferred between plastic and glass vials as needed for long-term storage or experimental use.
When storing peptides, remember to:
Research peptides are essential to unlocking future medical treatments, leveraging the impressive natural capabilities of these molecules. Over 7,000 naturally occurring peptides have been discovered, often playing vital roles in the human body as hormones, growth factors, neurotransmitters, and anti-infective agents.
Peptides are highly valued in drug development because they function as selective and effective signaling molecules. They typically bind to specific cell surface receptors, which triggers precise intracellular effects. In clinical trials, peptides have demonstrated:
This combination of attributes presents an enormous area of opportunity for therapeutic development.
Current research and the use of peptide-based pharmaceuticals are primarily driven by the need to address major diseases:
Beyond these areas, peptide research has expanded to include infectious diseases, inflammation, and rare diseases. Peptides also show excellent potential for use in diagnostics and vaccination.
Crucially, all this research and study—focused on translating peptide potential into future medicines—is entirely dependent upon research peptides to serve as the foundational basis for experimentation and development in the laboratory.
