Target Details

  • Target: CD19
  • Target background: CD19 is a member of the immunoglobulin superfamily and has two Ig like domains. It is a single chain glycoprotein, present on the surface of normal and neoplastic B-cells. CD19 is expressed at an early stage by progenitor B-cells in bone marrow and during all stages of B-cell maturation. This antigen is lost upon terminal differentiation to plasma cells. CD19 is important for detecting both normal and neoplastic B-cells. CD19 is present on neoplasms arising from early B-cells (e.g. acute leukemia of pre-B-cells) and more differentiated B-cell neoplasms (e.g. chronic lymphocytic leukemia and non-Hodgkin's lymphoma). Leukemia phenotype studies have demonstrated that the earliest and broadest B cell restricted antigen is the CD19 antigen. The CD19 cytoplasmic domain binds tyrosine kinases and PI-3 kinase.
