Product Description |
Recombinant Biotinylated Human CD40 Ligand/TNFSF5 Trimer Protein is expressed from HEK293 with His tag, Avi tag and Flag tag at the N-terminus.It contains Met113-Leu261. |
Product Background |
CD40 ligand or CD40L, also called CD154,- is a protein that is primarily expressed on activated T cells and is a member of the TNF superfamily of molecules. It binds to CD40 (protein) on antigen-presenting cells (APC), which leads to many effects depending on the target cell type. In total CD40L has three binding partners: CD40, α5β1 integrin and αIIbβ3. CD154 acts as a costimulatory molecule and is particularly important on a subset of T cells called T follicular helper cells. |
