Anti-CXCL4/PF4 Antibody is a humanized monoclonal antibody that binds specifically to the chemokine CXCL4 (PF4) with high affinity. By blocking its mediated biological effects and receptor interactions, it inhibits fibroblast activation and pro-inflammatory signaling. It serves as an important pharmacological tool for researching systemic sclerosis, thrombotic disorders, and inflammatory immune responses.
