Usage
It is a non-therapeutic biosimilar antibody, owning the same variable region from the corresponding approved therapeutic antibody. In conclusion, it is a research-grade biosimilar antibody and expressed in mammalian cell, which can be directly used as positive controls in drug discovery or used for rapid verification of the biological functions of target protein.
Description
This recombinant monoclonal antibody is a research-grade biosimilar of dapirolizumab pegol, targeting CD40LG (CD40 ligand; CD40L, also known as CD154)—a key T-cell costimulatory molecule in the CD40–CD40L axis that coordinates adaptive immune activation. CD40L signaling helps drive B-cell activation, germinal center responses, immunoglobulin class switching, and affinity maturation, and it also “licenses” antigen-presenting cells to support T-cell priming. Dysregulated CD40–CD40L signaling has been implicated in autoimmune pathology, including mechanisms relevant to systemic lupus erythematosus (SLE) such as amplified B-cell responses and autoantibody production.
Dapirolizumab pegol (CDP7657) is an Fc-free, PEG-conjugated anti-CD40L Fab’ designed to inhibit CD40L signaling and modulate immune activation pathways. This biosimilar provides the antibody reagent for studying CD40L target engagement, CD40-dependent immune synapse biology, and downstream functional readouts (e.g., B-cell activation programs, APC activation, and interferon-associated immune pathways) in controlled experimental systems—supporting mechanism-of-action research and assay development around CD40–CD40L pathway modulation.
