CD40L (human) (multimeric) (rec.) (Animal Free)

Product description: Recombinant protein. Human CD40L (aa 116-261) is fused at the N-terminus to mouse ACRP30headless (aa 18-111) and a FLAG®-tag. Source: CHO cells. Produced using animal component-free medium. Lyophilized. Contains PBS Induces B cell activation (as demonstrated by dose-dependent upregulation of CD86) (ED50: <1ng/ml). B cell expansion online protocol available. CD40 ligand (CD40L) expressed by activated T cells engages CD40 expressed by B cells and APCs. CD40L can provide signals to B cells that induce proliferation, immunoglobulin class switching and antibody secretion. CD40L has been used recently in Immunotherapy to activate tumor-infiltrated lymphocytes (TIL). MultimericCD40L™ is a high-activity construct in which two trimeric CD40 ligands are artificially linked via the collagen domain of ACRP30. This construct very effectively simulates the natural membrane-assisted aggregation of CD40L in vivo. It provides a simple and equally potent alternative to [CD40L+enhancer] combinations. MultimericCD40L™ has been shown to be a potent tool for B cell expansion. It also has big potential as a growth factor for tumor-infiltrating lymphocytes (TILs), which have been shown to be important for T cell therapy. The CD40L (human) (multimeric) (rec.) (Animal Free) has been produced in CHO in suspension using animal-component free medium and certified CHO cells.
