Description
CD19 protein plays a central role in B cell activation and humoral immune responses. It is required for the responsiveness of mature B cell to antigen stimulation, germinal center development, and antibody affinity maturation. CD19 has emerged as promising therapeutic target for hematologic cancers and solid tumors.
