Recombinant Human TGF-β1 Instruction

Transforming Growth Factor Beta 1 (TGF-β1) is a multifunctional cytokine that regulates cell proliferation, differentiation, apoptosis, and immune responses. It plays a central role in tissue fibrosis, wound healing, and immune tolerance. Recombinant Human TGF-β1 Protein (Y04201N) is expressed from mammalian cells. It contains AA Ala 279 - Ser 390 (Accession # P01137), and is widely used in advanced cell culture, immunology research, and regenerative medicine applications.

· 36 months at -20°C to -80°C in lyophilized state; · 6 months at -20°C to -80°C under sterile conditions after reconstitution;

· 7-10 days at 2°C to 8°C under sterile conditions after reconstitution;

· Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

· It is recommended to redissolve in 4mM HCL.

Q1: What is TGF-β1 mainly used for? TGF-β1 is primarily used for Treg differentiation, MSC lineage specification, EMT induction, fibrosis modeling, and immune regulation studies.

Q2: Is this TGF-β1 suitable for serum-free culture systems? Yes. EastMabBio recombinant TGF-β1 is compatible with serum-free, xeno-free, and chemically defined media systems.

Q3: How should recombinant TGF-β1 be stored? Lyophilized protein should be stored at -20°C or below. After reconstitution, aliquot and avoid repeated freeze-thaw cycles.

Q4: What shipping conditions are used? Products are shipped on dry ice with validated cold-chain packaging to maintain stability during international transportation. 

Q5: Do you provide QC documents? Yes. COA, MSDS, TSE-BSE statements, endotoxin reports, bioactivity data, and additional QC documentation are available upon request.
