P21 PEG MGF Detailed Product Description (Assay: 99.1%)

Product Name: P21 PEG MGF Lyophilized Peptide Powder

Purity Assay: 99.1% (HPLC Tested & Third-Party Verified)

Product Overview

P21 PEG MGF is a high-stability, long-acting pegylated variant of Mechano Growth Factor (MGF), optimized with advanced structural modification for enhanced molecular stability and prolonged biological half-life. This peptide is widely used in academic and biomedical laboratory research focusing on muscle cell proliferation, skeletal muscle repair, tissue regeneration, post-injury recovery mechanism, and physiological growth regulation. Presented as fine, uniform, sterile white lyophilized powder, P21 PEG MGF delivers consistent potency and extremely low impurity levels. Third-party HPLC certification confirms its purity reaches 99.1%, ensuring superior solubility, stable biological activity, and excellent batch-to-batch reproducibility for high-precision laboratory experiments. Compared with standard MGF, the PEG modification significantly reduces enzymatic degradation, extends active duration, and improves stability in liquid state, making P21 PEG MGF a premium-grade research peptide for advanced physiological and tissue repair studies.

Manufactured in GMP-compliant sterile workshops, every batch of P21 PEG MGF undergoes full standard quality control procedures, including HPLC purity verification, sterility testing, endotoxin analysis, residual moisture detection, heavy metal screening, and microbial limit testing. Complete batch COA and full test documentation are available upon request, providing full traceability and reliable quality assurance for global laboratory buyers and research institutions.

Key Product Features

• 99.1% High HPLC Purity – Third-party verified ultra-high purity eliminates impurity interference, ensuring accurate, stable, and repeatable experimental results
• P21 Optimized PEGylation Structure – Advanced pegylated modification greatly extends half-life, improves molecular stability, and provides longer-lasting effects than conventional MGF
• Strong Tissue Repair & Proliferation Activity – Ideal for research on muscle regeneration, cell growth activation, and tissue recovery mechanisms
• Excellent Water Solubility – Dissolves rapidly and completely in sterile water or bacteriostatic water to form clear, colorless, stable peptide solution
• Low-Endotoxin & Sterile Grade – Strict microbial and endotoxin control meets cell culture, biological testing, and preclinical research standards
• Perfect Batch Consistency – Fixed synthesis technology and strict quality standards ensure identical purity, appearance, and activity across all batches

Packaging Specifications

P21 PEG MGF is vacuum freeze-dried and individually sealed in sterile glass vials. The vacuum isolation packaging effectively prevents oxidation, moisture contamination, and activity loss during transportation and long-term storage. Standard packaging is 10 vials per box. Custom private label OEM packaging with exclusive customer branding is available with a customization MOQ of 100 boxes.

Storage Instructions & Shelf Life

Unopened lyophilized vials should be stored sealed at -20°C in a dry, dark, and clean environment, with a shelf life of 2 years under standard storage conditions. After reconstitution with sterile water, the peptide solution must be refrigerated at 2°C–8°C and used within 30 days to maintain maximum biological activity.
