Reference Standard Cartalax Polypeptide for Mesenchymal Stem Cell Biochemical Research

• Ultra-high Purity & Complete Molecular Structural Stability

  
  

  Adopting multi-stage ion exchange and gel filtration chromatographic separation plus low-temperature sterile vacuum lyophilization processes, the product overall purity reaches above 99%. HPLC, mass spectrometry and full-length peptide sequencing are adopted for full batch identity verification. Vacuum freeze-drying technology effectively locks intact tripeptide spatial structure and avoids molecular denaturation or fragmentation, delivering accurate, stable and reproducible experimental data for long-cycle cartilage cell and epigenetic research projects.
• Excellent Water Solubility & Simple Laboratory Operation

  
  

  The fluffy loose lyophilized powder dissolves rapidly in all conventional lab aqueous solvents without extra solubilizing additives. Operators can conveniently prepare high-concentration stock solutions and working diluents, fully matching daily operation demands of chondrocyte incubation, nucleic acid binding affinity detection and diversified in vitro biochemical analysis experiments.
• Unique Intranuclear Targeting Research Value

  
  

  As an ultra-small acidic tripeptide, Cartalax can independently cross cell membrane and enter cell nucleus without receptor-mediated endocytosis, which distinguishes it from most surface-targeted research peptides. It is the standardized experimental sample for studying peptide-DNA binding modes, epigenetic transcriptional modulation, chondrocyte extracellular matrix synthesis regulation and cell senescence marker expression control, covering multiple cutting-edge professional directions of tissue bioregulator peptide research.
• Comprehensive Traceable Quality Document System

  
  

  Customers can apply for a full set of supporting certification materials on demand, including Certificate of Analysis, HPLC chromatogram records, mass spectrum identification data and microbial limit inspection reports. All production flows follow unified manufacturing specifications for biological laboratory peptide reagents, meeting quality access standards of research institutions in various regions worldwide.
• Superior Long-Term Low-Temperature Storage Performance

  
  

  Equipped with light-blocking and moisture-proof fully sealed vial packaging, the product can maintain intact molecular conformation and stable biochemical properties for 24 months under -20°C storage environment. The prepared aqueous solution also keeps steady within the valid storage period, adapting to both short-term rapid detection tests and continuous long-cycle connective tissue cell culture research work.
