R&D & Industrial Production Background
Humanin HM peptide is a precision sequence-designed synthetic peptide substance in the professional field of molecular biochemistry and synthetic peptide research. Its unique amino acid sequence has passed systematic theoretical modeling, structural simulation and repeated laboratory synthesis verification by international basic research teams. Through long-term technical iteration, process debugging and production line intelligent upgrading, a fully enclosed and standardized automated production system for solid-phase peptide synthesis has been established, realizing stable large-scale manufacturing and consistent batch quality control.
Our factory adopts mature industrial SPPS solid-phase peptide synthesis technology to complete accurate splicing and assembly of Humanin HM peptide molecular chains. All synthetic procedures are automatically executed according to unified industrial standards, including fixed amino acid feeding ratios, precise peptide bond condensation time, stable system pH range and constant temperature reaction parameters. Raw material incoming records, production operation logs and technical parameter files of each batch are encrypted and permanently archived, realizing full-process traceability and reproducible inspection from raw material input to finished product output. The standardized manufacturing system ensures stable component proportion and excellent experimental repeatability for academic research and synthetic compound development projects.
After the completion of peptide chain assembly, the crude material undergoes multiple high-precision purification processes in sequence, including solid-phase resin cleavage, protective group removal, crude product concentration and precipitation pretreatment, multi-stage C18 reversed-phase chromatographic gradient impurity removal, ion exchange resin desalting treatment, residual solvent replacement, microporous membrane sterile filtration and vacuum low-temperature lyophilization shaping. The final product is uniform loose lyophilized powder with controllable impurity content and stable molecular spatial structure.
This high-purity synthetic peptide is widely used in global basic biochemical research and molecular material development. It is commonly applied to the exploration of intracellular peptide metabolic mechanisms, molecular structure-activity relationship analysis, synthetic compound preliminary screening and in-vitro molecular testing evaluation. It serves as a standard reference reagent for laboratory structural research, synthetic process debugging and compound comparison experiments, and is widely stored and used in university biochemical laboratories and biotechnology research institutions worldwide.
Physical and Chemical Properties
The finished Humanin HM peptide appears as pure white, uniform and loose lyophilized crystalline powder with fine and evenly distributed particles. The raw material features good powder fluidity without agglomeration, moisture caking, long-term storage discoloration, foreign impurity particles, mildew smell or pungent chemical odor. The advanced low-temperature vacuum lyophilization process effectively maintains the stable natural spatial structure of peptide molecules, ensuring stable physical and chemical properties for long-term laboratory preservation and experimental application.
Under original factory sealed, light-proof and low-temperature refrigerated storage conditions, the material maintains stable molecular structure without hydrolysis fracture or structural degradation. It supports high-precision micro-weighing, quantitative sampling, gradient solution preparation and low-temperature sealed preservation in standard laboratory environments. It effectively reduces experimental data errors caused by uneven raw material properties and significantly improves the stability and repeatability of biochemical comparison experiments.
Under normal temperature and normal pressure laboratory conditions, Humanin HM peptide can be completely dissolved in sterile purified deionized water and neutral PBS buffer solution. The dissolved solution is clear and transparent without suspended particles, precipitation or turbidity stratification. This peptide is slightly soluble in conventional polar organic solvents such as methanol and ethanol, and almost insoluble in non-polar organic solvents including n-hexane, petroleum ether and diethyl ether.
The aqueous solution prepared with pure water or buffer solvent maintains mild and stable pH characteristics, which will not change the basic acid-base balance of conventional biochemical reaction systems, and will not damage the structural stability of in-vitro biological samples. The material fully meets the basic technical requirements of mainstream molecular biochemistry laboratory experimental systems.
Each batch of products is tested by professional Karl Fischer moisture titration method, with internal controlled moisture content ≤5.0%. Low moisture content effectively slows down the molecular hydrolysis rate of peptide substances, extends the shelf life of sealed products, reduces effective component attenuation during long-term storage, and avoids experimental data deviation caused by raw material performance changes.
A 1% aqueous solution is prepared for pH testing, showing stable weak acidity with pH value ranging from 4.5 to 6.5. The material has mild chemical properties without strong corrosiveness or irritation, fully conforming to the universal safety standards for laboratory biochemical reagents.
Quality Inspection Specification
Reversed Phase High Performance Liquid Chromatography (RP-HPLC) is adopted as the core detection method for product purity verification. Each batch of goods is accompanied with official COA certificate of analysis in both paper and electronic PDF versions for customer filing and batch record management. All testing items are limited to physical and chemical index detection of synthetic chemical raw materials, without any biological efficacy judgment or application-related evaluation content. The detailed quality standards are as follows:
Main Component Purity: The HPLC purity of Humanin HM peptide main component is ≥99.0%. Deeply purified finished products completely remove unreacted amino acid monomers, incomplete peptide fragments and synthetic byproducts, ensuring high consistency of component content among different batches and improving the comparability of laboratory experimental data.
Maximum Single Unknown Impurity: The content of any single unknown impurity is controlled within ≤0.5%, which avoids abnormal data fluctuation caused by single interfering components and ensures the accuracy of molecular comparison experiments.
Total Impurity Content: The total content of all known and unknown impurities is ≤1.0%, meeting the international standard of high-purity research-grade biochemical raw materials, suitable for high-precision laboratory research and compound screening experiments.
Microbial Index Control: The microbial index of raw materials is strictly controlled to meet the aseptic standard of in-vitro biochemical experiments, effectively avoiding microbial interference in laboratory solution systems and ensuring the cleanliness and stability of experimental environments.
Qualitative Identification: The molecular weight detected by mass spectrometry is completely consistent with the theoretical molecular weight of Humanin HM peptide, and the HPLC peak retention time matches the standard reference spectrum. It can be used as a qualitative standard sample for molecular identification and content calibration in peptide biochemical experiments.
Storage Specification
Unopened sealed products should be stored in a constant temperature refrigerated environment of 2℃~8℃, kept away from humidity, strong light and high-temperature heat sources. The valid shelf life of original sealed products is 24 months.
After opening and sampling, the remaining solid raw materials need to be sealed and refrigerated immediately. The prepared liquid stock solution should be packed in micro tubes and stored at -20℃ away from light. Repeated freezing and thawing should be avoided. It is recommended to complete the experimental use within one month after sub-packaging to prevent molecular structural degradation.
Long-term open placement at room temperature is prohibited. Humanin HM peptide powder has slight hygroscopicity, and open placement will easily absorb moisture in the air and cause molecular structural changes. The container must be completely sealed immediately after each sampling to ensure long-term material stability and experimental repeatability.
