Application Areas
Skin and Wound Healing: Models of lacerations, burns, diabetic ulcers, and corneal alkali burns-accelerate epithelialization and orderly collagen deposition, reducing scar area.
Tendon and Ligament Repair: Models of Achilles tendon rupture, rotator cuff injury, and ligament tears-promote fibroblast migration and collagen cross-linking, improving biomechanical strength.
Muscle Injury Repair: Models of crush injuries, transection injuries, and motor muscle fiber injuries-accelerate the activation of muscle satellite cells and muscle fiber regeneration.
Bone and Joint Repair: Models of fracture healing, cartilage defects, and arthritis-regulate MMP expression, promote callus mineralization, and protect the cartilage matrix.
Cardiovascular Protection Research: Models of myocardial infarction, myocardial ischemia-reperfusion, and cardiac rupture prevention-mobilize epicardial progenitor cells, promote cardiomyocyte survival, and angiogenesis.
Neuroprotection Research: Models of traumatic brain injury, cerebral ischemia, and spinal cord injury-reduce neuronal apoptosis and promote axonal regeneration.
Anti-fibrosis Research: Pulmonary fibrosis, liver fibrosis, and renal fibrosis models-reducing collagen deposition and inhibiting myofibroblast activation.
Hair follicles and skin appendages: hair growth cycle regulation and hair follicle stem cell activation research.
Gastrointestinal repair: intestinal mucosal injury and inflammatory bowel disease models-promoting epithelial barrier repair.
Why Choose Us (Source Factory)
Although TB-500 is a 7-peptide, N-terminal acetylation capping, double Lys hydrophilic aggregation tendency, and acetate/moisture control can affect HPLC purity and lyophilization flowability. As a peptide source factory, we offer:
Direct supply: self-produced and self-sold, no middlemen markups; 10 mg–kg tiered ordering, controllable delivery time and price.
Professional equipment: Fmoc-SPPS + preparative-grade RP-HPLC purification + LC-MS / amino acid analysis / acetate moisture (Karl Fischer) detection, each batch includes HPLC ≥98% (customizable ≥99%), MS, and COA.
Stable Quality: Internally controlled monomer purity, single impurities, acetylation integrity, moisture (<5%), and endotoxin (research grade optional); nitrogen-filled aluminum foil packaging prevents moisture absorption and clumping.
Stable Supply: Maintains pilot-scale inventory and scale-up process data to avoid purity drops, slow dissolution, or supply disruptions associated with batch changes in commercially available "repackaged bottles."
Clear Compliance: Clearly labeled "Research Use Only," with support for institutional audits, export cold chain, and reconstitution technology consultation; differentiates between "7-peptide fragment" and "full-length Tβ4" COA templates to prevent confusion.
Storage and Usage Instructions
1. Storage Conditions
Unopened Lyophilized Powder: Sealed, protected from light and moisture; -20℃ for long-term storage (recommended), 2–8℃ for short-term storage ≤30 days; shelf life 24 months.
Opened: Store in a desiccator/nitrogen-filled container, avoid repeated exposure to room temperature, and aliquot according to usage.
Reconstituted solution: Store at 2–8℃ protected from light. Reconstituted with BAC in water, it can be used for 14 days; reconstituted with sterile water, it is recommended to use within 24–72 hours. Long-term storage can be aliquoted at -20℃ (repeated freezing and thawing at -80℃ is not recommended); repeated freeze-thaw cycles are strictly prohibited.
Contraindications: Avoid prolonged exposure to strong light, opening at high humidity, high temperatures (>30℃), vigorous shaking, and strong acids or bases (pH 6.5–7.5 is relatively stable).
2. Reconstitution Recommendations (Research Grade Lyophilized Powder)
Let the lyophilized powder warm to room temperature for 15–20 minutes (to prevent condensation dilution); use sterile antibacterial solution (BAC 0.9% benzyl alcohol)/sterile water/physiological saline; slowly pour along the bottle wall, never directly onto the powder, gently swirl without shaking, and let stand for 1–3 minutes until clear and colorless (10 mg + 2 mL ≈ 5 mg/mL).
Because both Lys groups are hydrophilic, water solubility is generally good. If local aggregation occurs, use pH 7.4 PBS or 0.1% acetic acid aqueous solution to aid dissolution. Do not use pure DMSO for extended periods.
Discard any solution that is turbid, pale yellow, or contains particles.
3. Experimental Notes
For in vitro/animal research models only; do not claim direct injection into humans.
Working concentration varies depending on the model (common range for cell experiments is 0.1–100 μg/mL), refer to literature and preliminary experiments for actual results.
Incompatible with strong oxidizing agents; contains acetylated N-terminus; pay attention to acetyl correction in amino acid analysis.
