Cartalax Synthetic Biochemical Peptide Raw Material For Laboratory Research

Cartalax is a synthetic peptide produced through mature solid phase peptide synthesis technology. The product is white lyophilized powder, only supplied for laboratory research purposes. It is biochemical raw material and cannot be used for clinical treatment, food processing or cosmetic formulation. Strict internal quality control will be implemented before delivery. Each batch is tested to guarantee stable quality, and COA document can be offered for laboratory reference.

Reliable purity: Each batch is tested before packing to maintain consistent quality

1. Lyophilized powder form, easy to store and prepare under suitable low temperature sealed environment
2. Produced by proven solid-phase peptide synthesis technique
3. Complete quality inspection process, all indicators are checked before shipment
4. Cartalax features ultra-low molecular weight that enables free penetration through cell and nuclear membranes, directly binding to chromatin and gene promoter segments of chondrocytes and connective tissue fibroblasts to activate multi-layer cartilage regenerative and protective transcriptional networks within in vitro culture systems:
   1. Upregulate the master chondrogenic transcription factor SOX9, boost transcription of core cartilage structural genes including COL2A1 and ACAN, promote continuous synthesis of type II collagen and aggrecan to maintain cartilage elastic structural integrity;
   2. Suppress overexpression of matrix catabolic enzymes MMP-13 and ADAMTS-5 triggered by inflammatory stimulation, slow excessive breakdown of extracellular matrix inside damaged joint tissue co-culture models;
   3. Stimulate proliferative activity of quiescent chondrocyte precursor cells, raise expression of cell proliferation markers Ki-67 and CD98hc to expand viable cartilage cell populations during long-term incubation cycles;
   4. Inhibit apoptosis signaling protein caspase-3, reduce oxidative stress-induced programmed death of chondrocytes and relieve age-related cellular senescence by downregulating senescence markers p16, p21;
   5. Balance release of pro-inflammatory mediators in cartilage resident cells, reconstruct a mild non-destructive local microenvironment to cut persistent inflammatory erosion of chondrocyte structures;
   6. Optimize metabolic signal communication between chondrocytes and synovial tissue cells, ease abnormal metabolic imbalance induced by simulated mechanical load and chronic inflammatory stress.
