Core Molecular Specs & Technical Index
Thymosin Alpha 1 (TA1) is a 28-amino-acid peptide with a molecular weight of approximately 3108.3 Da. For B2B buyers, the critical technical parameters include a minimum purity of 98.5% by HPLC, a net peptide content above 80%, and a trifluoroacetic acid (TFA) content below 1.0%. The peptide is supplied as a lyophilized white powder, highly soluble in water and phosphate-buffered saline, with optimal storage at -20°C in airtight, desiccated conditions. Stability data confirms a shelf life of 24 months when stored properly, with less than 2% degradation under recommended conditions.
- Purity by HPLC: ≥98.5% (main peak area normalization), with single impurity ≤0.5%
- Net Peptide Content: ≥80% (by UV or amino acid analysis)
- Solubility: ≥10 mg/mL in water, ≥20 mg/mL in PBS (pH 7.4)
- Storage Stability: Lyophilized powder stable for 24 months at -20°C; reconstituted solution stable for 7 days at 2-8°C
- Endotoxin Level: ≤0.5 EU/mg (suitable for cosmetic and research applications)
Industry data from the Peptide Therapeutics Foundation indicates that 92% of B2B buyers prioritize purity above 98% for cosmetic-grade peptides, as lower purity correlates with reduced formulation stability and increased batch-to-batch variability.
Manufacturing & Quality Control
Our TA1 peptide is manufactured using solid-phase peptide synthesis (SPPS) on a commercial scale, followed by reverse-phase high-performance liquid chromatography (RP-HPLC) purification. The process yields a product with consistent molecular weight and minimal racemization. Quality control includes three independent tests: HPLC for purity, mass spectrometry for identity, and amino acid analysis for composition. Each batch is accompanied by a Certificate of Analysis (CoA) detailing all specifications.
- Production Process: SPPS with Fmoc chemistry, cleavage, and global deprotection
- Purification: RP-HPLC with C18 columns, gradient elution, and lyophilization
- Third-Party Testing: Independent lab verification for purity, endotoxin, and heavy metals
- Certifications: ISO 9001:2015 for quality management, GMP compliance for cosmetic raw materials
- Batch Traceability: Full documentation from raw material sourcing to final packaging
Commercial Application Scenarios
TA1 peptide is widely used in cosmetic formulations as a bioactive ingredient for anti-aging and skin conditioning products. In lab research, it serves as a standard for immunological studies and peptide stability assays. For bulk wholesale, it is supplied in multi-gram quantities for formulation development and commercial production. Typical usage levels in cosmetics range from 0.1% to 1.0% by weight, depending on the desired activity and product type.
- Cosmetic Formulation: Added to serums, creams, and masks for skin firming and texture improvement
- Lab Research: Used as a positive control in peptide stability and bioactivity assays
- Bulk Wholesale: Supplied in 1g, 5g, and 10g vials for large-scale production
- Custom Synthesis: Available for modified sequences or specific purity requirements

Bulk Purchase Selection Guide
When sourcing TA1 peptide for B2B wholesale, buyers must avoid common pitfalls such as accepting low-purity material without HPLC data or ignoring endotoxin levels. Selection standards should include a minimum purity of 98.5%, verified by third-party testing, and a clear certificate of analysis. The buyer checklist below ensures a reliable procurement process.
- Common Pitfalls: Accepting verbal purity claims without HPLC chromatograms; ignoring storage stability data; purchasing from unverified suppliers
- Selection Standards: Purity ≥98.5%, net peptide ≥80%, endotoxin ≤0.5 EU/mg, full CoA provided
- Buyer Checklist: Request batch-specific CoA, verify third-party test results, confirm storage conditions, check lead time and minimum order quantity
- Supplier Verification: Look for ISO certification, GMP compliance, and positive client references
