Description

Product Detail

Chonluten Lab-Grade Respiratory Protective Peptide Compound is high-purity synthetic polypeptide raw material exclusively developed for in-vitro lung epithelial cell and respiratory biochemical research. The product adopts full-enclosed solid-phase peptide synthesis, reversed-phase multi-stage chromatographic purification and low-temperature vacuum lyophilization process, fully removing residual amino acid monomers, coupling reagents and microbial contaminants. The finished product is uniform off-white fine lyophilized powder, with HPLC main peptide purity ≥99%, each single unknown impurity less than 0.1%, total related impurities controlled below 1.0%. The whole production line complies with laboratory biological raw material quality control standards, strictly limits endotoxin, heavy metal and microbial residues, effectively reduces lung epithelial cell oxidative damage and unstable experimental model repeatability caused by impurity interference, and guarantees stable, reproducible data output for respiratory protection mechanism experiments. Its unique polypeptide sequence can regulate intracellular anti-inflammatory and anti-apoptosis signaling pathways in respiratory cells, widely applied to primary alveolar epithelial cell culture, lung injury cell model construction, respiratory protective target screening and high-purity peptide raw material matching for respiratory biochemistry laboratories and pulmonary disease R&D institutions. Each batch is supplied with complete unmodified official certification documents, including full-item COA inspection report, peptide HPLC chromatogram, molecular weight mass spectrometry identification data and TDS technical data sheet, fully meeting laboratory filing standards and peer-reviewed academic journal submission requirements.

Core Product Advantages

Consistent ultra-high purity across batches, stable performance in lung cell experiments

All raw material batch records, synthesis process parameters and finished full-index test data are permanently archived for cross-batch consistency comparison, avoiding purity fluctuation interfering with alveolar cell activity test results. Complete original instrument spectrum data without manual modification will be delivered with every order, convenient for laboratory data archiving and research manuscript peer review.
Free full-cycle professional biochemical technical support

Our R&D engineers with years of primary lung epithelial cell culture research experience provide free online technical consultation during working hours, covering peptide ultra-low temperature storage specifications, cell culture medium dilution matching ratio, lung injury inflammatory marker abnormal data analysis and experimental scheme optimization guidance. Custom split vacuum packaging and OEM private label services are available according to personalized orders from research institutes.
Complete compliant certification materials for academic paper publication

Unprocessed original chromatogram and mass spectrum raw data can be directly submitted to journal reviewers, saving researchers massive data sorting time and significantly improving the acceptance rate of respiratory biochemistry research papers.
Factory direct supply, permanent stable spot inventory & temperature-controlled cross-border cold-chain logistics

We are professional synthetic peptide manufacturer with long-term sufficient spot stock; replenishment orders from long-term cooperative laboratories get priority production and delivery. All products adopt ultra-low temperature insulated vacuum glass vial packaging, which can fully lock polypeptide molecular activity during long-distance international transportation, prevent hydrolysis and deactivation, and realize on-time delivery to global customers.
Independent isolated segmented production workshops to block cross-contamination risks

Synthesis, purification, lyophilization and subpackaging workshops are mutually isolated with dedicated exclusive production equipment, fundamentally cutting off cross-contamination from other biochemical raw materials and different peptide products.
Full order tracking & rapid after-sales resolution mechanism

Special customer service tracks the whole process of quality inspection, vacuum encapsulation, cold-chain transportation and customs clearance. Targeted rapid solutions will be provided for all product quality and experimental technical problems; long-term cooperative clients enjoy exclusive one-on-one long-term technical follow-up service.

Standard Storage Guidance

To fully retain polypeptide molecular stability and native biological activity:

Short-term storage within 6 months: Tighten the vial cap completely, store in dry, dark environment at 2–8°C.

Long-term storage over 6 months: Must be hermetically stored under -20°C ultra-low temperature refrigeration. Prevent moisture infiltration, repeated temperature alternation and direct ultraviolet irradiation.

Before weighing and dissolving operation, place the sealed container at room temperature for full temperature balance to avoid condensed water polluting lyophilized powder.

Optional Packaging Specifications

Standard specifications: 10mg / 50mg / 100mg vacuum sealed glass vial. Customized net weight split packaging and private label OEM labeling can be arranged according to customer demands.

Disclaimer

This laboratory lyophilized polypeptide compound is only limited to in-vitro respiratory biochemical research, lung epithelial cell culture testing and pulmonary protection mechanism exploration. It is strictly prohibited for direct oral administration to human or animal bodies, clinical pharmaceutical preparation, clinical respiratory disease diagnosis and all clinical therapeutic applications.
