FC - Quality tested

Application Notes:

The TKS-1 antibody inhibits binding of soluble 4-1BB to 4-1BBL in vitro. Additional reported applications (for the relevant formats) include: in vitro blocking the binding of 4-1BB to 4-1BBL1. For most successful immunofluorescent staining results, it may be important to maximize signal over background by using a relatively bright fluorochrome-antibody conjugate or by using a high sensitivity, three-layer staining technique (e.g., including a biotinylated antibody or biotinylated anti-rat IgG second step , followed by SAv-PE ).

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Mouse B cell line 2PK3

Mouse B cell line 2PK3 stained with TKS-1 PE


4-1BB ligand, also known as CD137L, is a 97 kD member of the TNF superfamily present on antigen-presenting cells (dendritic cells and macrophages) and activated B and T lymphocytes. 4-1BBL interacts with 4-1BB (CDw137) to induce T and B cell costimulation.

Other Names: 4-1BBL, CD137L, TNFSF9
Structure: NGF/TNF superfamily, 97 kD
Distribution: Activated B cells and T cells, macrophages, and dendritic cells
Function: T cell costimulation
Ligand Receptor: 4-1BB (CDw137)
