Sermorelin, a classic GHRH pathway research peptide, is widely used in the following fields:
Application Areas
Endocrine and Metabolic Research: Pituitary growth hormone axis regulation, GHRH receptor signal transduction (cAMP/PKA/CREB pathway), physiological GH pulse pattern modeling
Pharmacological Comparative Studies: Pharmacodynamic and half-life comparisons with modified GHRH analogs such as CJC-1295, Tesamorelin, and Mod GRF 1-29
Cellular and Molecular Biology: In vitro pituitary cell culture, functional validation of GHRHR expression systems, dose-response relationship studies
Stability and Degradation Studies: Clearance kinetics of natural sequences under enzymatic hydrolysis environments such as DPP-IV, metabolic behavior analysis of unmodified peptides
Formulation Development: Optimization of lyophilized formulations, screening of sustained-release delivery systems, feasibility assessment of compound formulations
Why Choose Us
1. Direct Factory, Excellent Cost and Delivery Time
We have our own synthetic production line, with fully automated control from amino acid raw materials to solid-phase synthesis (SPPS), cutting and purification, and lyophilization, eliminating middlemen markups. 1. Ample production capacity, supporting stable supply from gram to kilogram levels, controllable delivery time, and competitive pricing.
2. Professional production equipment and mature, reliable processes.
Synthesis platform: Equipped with a multi-channel automated peptide synthesizer, employing the Fmoc solid-phase synthesis strategy, ensuring high coupling efficiency and excellent racemic control.
Purification system: Equipped with preparative-grade reversed-phase HPLC (RP-HPLC) and ion-exchange chromatography equipment, effectively removing missing peptides, truncated peptides, and racemic impurities.
Freeze-drying facilities: Professional freeze dryers control residual moisture to <1% (Karl Fischer titration verification), significantly reducing the risk of asparagine deamidation and methionine oxidation, extending raw material shelf life.
Quality control laboratory: Equipped with analytical HPLC, LC-MS, and MALDI-TOF, performing four-level quality control for each batch: synthesis-purification-detection-release.
3. Stable supply and guaranteed supply chain.
Raw material reserves: Maintaining safety stock of key amino acid monomers and resins to cope with market fluctuations.
Production Capacity Flexibility: Standard products are readily available, and customized specifications support flexible production scheduling.
Cold Chain Logistics: Finished products are stored at -20°C. Temperature-controlled packaging and temperature recorders are used for shipping to ensure full traceability throughout the transportation process.
4. Stable Quality and High Batch Consistency: Standardized Operating Procedures (SOPs) and Batch Production Records (BPR) are established, ensuring full traceability from material input to release.
Each batch of raw materials provides HPLC purity chromatograms, MS molecular weight confirmation, and a Certificate of Account (COA), ensuring verifiable and authentic data.
Strict adherence to ISO-level cleanroom operating procedures minimizes the risk of microbial and particulate contamination.
Storage and Usage Instructions
【Unopened Lyophilized Powder Storage】
Temperature: -20°C ± 5°C for frozen storage (best for long-term stability); short-term (≤24 months) can be refrigerated at 2–8°C.
Humidity: Sealed and moisture-proof; recommended to store with desiccant (silica gel/molecular sieve); relative humidity <30% RH.
Light: Store away from light; recommended to use original packaging aluminum foil bag or amber container.
Shelf Life: Under the above conditions, unopened lyophilized powder has a stability of 24–36 months.
⚠️ Important Note: Although lyophilized powder can withstand brief exposure to room temperature during normal transportation, please transfer it to -20°C for storage as soon as possible after receiving the goods. Do not repeatedly freeze and thaw.
