PRIMARY CATALOG / OPEN MEMBER WHOLESALE
Wholesale Kits.
Ten vials each.
Our main catalog is built around complete kits of ten matching vials, with fast, discreet tracked U.S. shipping. Browse every standard kit and price first; single-vial inventory remains available farther down the page.

Real products, current listed prices, and direct links into the full peptide catalog.
VIAL FORMAT / LAB HANDLING
Lyophilized now.
Reconstituted for research.
PSC catalog items are supplied as lyophilized—freeze-dried—research material.
Reconstitution is required before research use. Solvent choice and procedure vary by material; use a validated compound-specific protocol.
Store unopened lyophilized vials frozen. After reconstitution, refrigerate for short-term research handling unless a validated compound-specific protocol requires different conditions.

MOLECULAR FIELD GUIDE / 02
Peptide science,
mapped visually.
A peptide is not defined by a marketing category. Its amino-acid order, side-chain chemistry, charge, flexibility, and three-dimensional ensemble shape what researchers can observe.
01 / PEPTIDE ANATOMYNCBI SOURCE ↗
A chain with direction.
Amino acids are linked head-to-tail by covalent peptide bonds. By convention, a sequence is written from its amino terminus to its carboxyl terminus: N → C.
H₂N→ALA—GLY—SER—LEU→COOH
NONPOLARALA · VAL · LEU
Side chains that tend to avoid water.
POLARSER · THR · GLN
Side chains that form favorable polar interactions.
ACIDICASP · GLU
Often negatively charged near neutral pH.
BASICLYS · ARG · HIS
Often positively charged, depending on pH.
Property groups are simplified teaching categories; charge and behavior depend on the full sequence and experimental environment.
COMMON BUILDING BLOCKS
One alphabet, enormous variety.
Proteins commonly use 20 encoded amino acids. Reordering even a short chain produces a different primary sequence.
CONFORMATIONAL ENSEMBLE
Shape is more than a static model.
Hydrogen bonding, charge, hydrophobic effects, backbone flexibility, and disulfide bridges can favor different conformations.
CELL SIGNALING
Binding starts a conversation.
Many peptide signals bind cell-surface receptors, which can relay information through intracellular messengers and kinase cascades.
STEPWISE SYNTHESIS
Built one residue at a time.
Solid-phase peptide synthesis anchors a growing chain to a support so amino acids can be added sequentially.
SEQUENCE-TO-SIGNAL MODEL
How a research question moves from molecule to measurement.
Which residues, in what order?
Charge, polarity, and hydrophobicity.
Flexible shapes available to the chain.
Recognition, affinity, and selectivity.
The measured response in a defined model.
Conceptual research map only. A category or binding observation does not establish a health benefit, treatment, safety, or intended use.
PEPTIDE ARCHITECTURE / 03
Small chains.
Complex signals.
Peptides are short chains of amino acids joined by peptide bonds. Their sequence, length, charge, and three-dimensional conformation shape how they behave in laboratory models.
Hydrophobic Polar Charged
Illustrative amino-acid chain—not a product-specific sequence.
PRIMARY STRUCTUREN-TERMINUS → C-TERMINUS
01020304050607
Sequence variants
Researchers compare residue substitutions, truncations, cyclization, and conjugation to study how structure changes an observed interaction.
Affinity is not the whole story
Association, dissociation, receptor selectivity, and experimental context all influence how binding data are interpreted.
Peptides can change over time
Proteolysis, oxidation, deamidation, adsorption, precipitation, and aggregation are distinct research considerations.
Research areas describe subjects of laboratory investigation—not established health benefits, treatments, or intended uses.
