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.

Recombinant Human 4-1BB Ligand, Fc Tag (41L-H5257) is expressed from human 293 cells (HEK293). It contains AA Ala 50 - Glu 254 (Accession # NP_003802).
Predicted N-terminus: Ala 50

Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus.The protein has a calculated MW of 47.5 kDa. The protein migrates as 52 kDa under reducing (R) condition (SDS-PAGE).

Less than 1.0 EU per μg by the LAL method.

>95% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

See Certificate of Analysis for details of reconstitution instruction and specific concentration.

Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at:
In lyophilized state for 1 year (4°C-8°C); After reconstitution under sterile conditions for 1 month (4°C-8°C) or 3 months (-20°C to -70°C).
