4-1BB Ligand,TNFSF9,CD137L
Human 4-1BB Ligand, Mouse IgG2a Fc Tag, low endotoxin (41L-H5254) is expressed from human 293 cells (HEK293). It contains AA Ala 50 - Glu 254 (Accession # P41273-1).
Predicted N-terminus: Ala 50
Request for sequence
This protein carries a mouse IgG2a Fc tag at the C-terminus.
The protein has a calculated MW of 48.3 kDa. The protein migrates as 47-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 0.1 EU per μg by the LAL method.
>90% 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.

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.
