What is Melts Pro™ Selank + Semax Dissolving Strips?
Melts Pro™ Selank + Semax Dissolving Strips fall within the "melts" product category: pre-formulated dissolving thin-film strips that carry defined research peptides in a solid, ready-to-handle matrix rather than as a lyophilized powder or reconstituted solution. Each unit contains 20 individual strips. The format combines two distinct synthetic peptides, Selank and Semax, in a single dissolving-film matrix intended solely for in-vitro and laboratory research applications.
Structurally, both actives are short synthetic peptides classified as heptapeptides (seven amino-acid residues each). Selank is a synthetic analog derived from the endogenous immunomodulatory peptide tuftsin, engineered with terminal modifications that increase its stability relative to the parent sequence. Semax is a synthetic peptide related to a fragment of the adrenocorticotropic hormone (ACTH) family and is likewise stabilized against enzymatic degradation. Co-formulating the two provides a single reference material for studies that examine these neuropeptide analogs in parallel. The material is characterized as greater than or equal to 99% pure by HPLC, with a Certificate of Analysis (COA) available.
Both Selank and Semax are referenced in neuropeptide and central-nervous-system research literature, where synthetic regulatory peptides are studied as tool compounds in in-vitro and preclinical model systems. This listing describes the identity, composition, and physical form of the material only. No physiological, therapeutic, or performance outcome is claimed or implied; the product is supplied strictly for research use and is not intended for diagnostic, therapeutic, or human or veterinary use of any kind.
Reconstitution & handling
Unlike lyophilized peptide powders, this material is supplied as a finished dissolving strip and requires no reconstitution, weighing, or solvent handling prior to use in a laboratory workflow. Each strip is a thin, hydrophilic polymer film in which the peptide content is dispersed throughout a water-soluble matrix; on contact with aqueous moisture the film matrix hydrates and disperses, releasing its contents into solution.
For research procedures that call for an aqueous working stock, a strip can be dissolved in a defined volume of laboratory-grade aqueous medium such as bacteriostatic or sterile water. Because both Selank and Semax are hydrophilic peptides, they disperse readily in aqueous buffers without organic co-solvents. Strips should be handled with clean, dry gloved hands or forceps, kept away from ambient humidity until the point of use, and returned to their sealed packaging promptly, since the polymer matrix is hygroscopic and will begin to soften if exposed to moisture or high relative humidity.
Storage & stability
In their sealed, moisture-barrier packaging the dissolving strips are stable at room temperature away from direct light and humidity; for extended storage, a cool, dry environment or refrigeration further protects peptide integrity and preserves the physical properties of the film matrix. The primary stability risk for a thin-film format is moisture ingress, which can cause the strips to soften, tack, or prematurely dissolve, so packaging should remain sealed until use and any included desiccant should be retained. An aqueous solution prepared by dissolving a strip should be treated as a fresh working stock, kept chilled, protected from repeated warming, and used within a short window, as peptides in solution are generally less stable than in the dry film state.
How it's tested
Identity and purity are established analytically prior to release. Reversed-phase high-performance liquid chromatography (HPLC) is used to determine chromatographic purity, supporting the greater than or equal to 99% specification, and to resolve the peptide components as distinct chromatographic peaks. These results, together with appearance and related quality parameters, are documented on a lot-specific Certificate of Analysis (COA) that is available for the material, providing traceable verification of composition for research recordkeeping.
