OX40L is a membrane-expressed cytokine that belongs to the TNF ligand family. It acts as costimulator through interaction with its ligand OX40 on T cells, stimulating T cell activation, proliferation and cytokine production. OX40L is expressed on antigen presenting cells including B cells, dendritic cells, mast cells and endothelium. MegaOX40L(TM) is a high activity construct in which two trimeric OX40L ligands are artificially linked via the collagen domain of ACRP30. This construct very effectively activates T cell proliferation.
Biological Activity:
Activates T cell proliferation.
Sequence:
The extracellular domain of mouse OX40L (aa 52-199) is fused at the N-terminus to mouse ACRP30headless (aa 18-111) and a FLAG(R)-tag.
Storage and Stability:
Short-term Storage: +4 degrees C
Long-term Storage: -20 degrees C
Stable for at least 6 months after receipt when stored at -20 degrees C.
