Human 4-1BB Ligand / TNFSF9 (71-254) Protein, His, Flag Tag, active trimer (MALS verified)

Tumor necrosis factor ligand superfamily member 9 (4-1BBL) is also known as 4-1BB ligand, CD137L or TNFSF9, which is a cytokine that binds to TNFRSF9. 4-1BBL is the high affinity ligand of 4-1BB. 4-1BBL induces the proliferation of activated peripheral blood T-cells. Also, 4-1BBL may have a role in activation-induced cell death (AICD) . Furthermore, 4-1BBL may play a role in cognate interactions between T-cells and B-cells/macrophages. As for diseases, 4-1BBL is involved in cancers, infectious diseases and autoimmune diseases.

This protein carries a polyhistidine tag at the N-terminus, followed by a flag tag. The protein has a calculated MW of 62.8 kDa. The protein migrates as 55-60 kDa under non-reducing (NR) condition (SDS-PAGE) .

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.
