Letaplimab (IBI-188) is a human IgG4 monoclonal antibody targeting CD47, a protein frequently overexpressed on the surface of cancer cells and acting as a ligand for signal regulatory protein alpha (SIRPα). By binding to CD47, Letaplimab disrupts its interaction with SIRPα, thereby enhancing the phagocytosis of tumor cells. This mechanism positions Letaplimab as a promising therapeutic agent in the field of oncology, particularly for the treatment of cancers characterized by high CD47 expression.

Frequently Asked Questions
What are Biosimilar Antibodies?
Biosimilar antibodies are research-grade recombinant antibodies designed to closely resemble approved therapeutic antibodies in terms of amino acid sequence, structural characteristics, and biological activity. These antibodies are generated using recombinant expression technologies and retain the same variable regions as their corresponding reference therapeutics, thereby preserving target specificity and binding affinity. Owing to these properties, biosimilar antibodies serve as reliable and cost-effective research reagents for applications in drug discovery, pharmacological studies, and basic biomedical research.
Research-grade biosimilar antibodies have been successfully expressed and functionally validated against a wide range of widely studied targets. These antibodies can be directly utilized as positive control reagents in drug discovery programs, as well as reference tools for rapid verification of the biological functions of target proteins in biochemical and cellular assays.
