Quick Facts About RagifilimabWhat is Ragifilimab?Ragifilimab is an investigational anti-CD47 monoclonal antibody developed to block the CD47-SIRPα interaction, thereby enhancing macropha

A macrophage does not decide to eat; it counts votes. Every particle it touches carries a mixture of pro-phagocytic and inhibitory ligands, and engulfment follows only when the activating tally clear

A depletion experiment is only as good as the depletion you can prove. Injecting a functional-grade antibody and assuming the population is gone is the most common failure mode in in vivo immunology.

One of the greatest challenges in cancer therapy is how tumors evade immune detection. Among the mechanisms cancer cells exploit, the CD47 pathway has emerged as a major player in helping

Quick Facts About NarnatumabWhat is Narnatumab?Narnatumab is a monoclonal antibody targeting CD47, a key immune checkpoint that helps cancer cells evade destruction by the immune system.
