TNFSF9 Human Recombinant fused to 37 amino acids His tag at N-terminus produced in E.Coli is a single, non-glycosylated polypeptide chain containing 222 amino acids (71-254 a.a.) and having a molecular mass of 23.8 kDa.
The TNFSF9 37 aa His tag fusion protein is purified by proprietary chromatographic techniques.

Recombinant 4-1BBL solution (1mg/ml) contains 20mM Tris-HCl buffer pH-8, 100mM NaCl and 20% glycerol.

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
