Datasheet

MSDS

Mouse CD19 (Cluster of Differentiation 19) is a Type I transmembrane glycoprotein in the immunoglobulin superfamily. It is also known as B-Lymphocyte Surface Antigen B4, B4, CVID3, CD19 molecule, B-lymphocyte antigen CD19, and T-Cell Surface Antigen Leu-12. This recombinant CD19 protein is a cis-dimer protein (CSP-124-01) and contains a CD19 extracellular domain (UniProt# P25918, amino acids Arg19-Gly287) fused with a dimer motif followed by a His tag at the C-terminus. This dimeric protein is expressed in HEK293 cells and is bioactive. It also binds CD19-specific antibodies. This CD19 dimer can be used as an antigen for in vitro assays and antibody screening, and an immunogen for immunization to generate antibodies targeting more conformational epitopes.

Protein Construct: CD19 protein dimer contains a CD19 extracellular domainfused with a dimer motif followed by a His tag at the C-terminus.

Background and Alternate Names

Mouse Cluster of Differentiation 19 (CD19) is a Type I transmembrane glycoprotein in the immunoglobulin superfamily. CD19 is also known as B-Lymphocyte Surface Antigen B4, CVID3, B-lymphocyte antigen CD19, and T-Cell Surface Antigen Leu-12. CD19 is expressed on B cells throughout B cell development, but lost in plasma cells, and is also expressed on follicular dendritic cells. CD19 contains two extracellular C2-set Immunoglobulin-like (Ig-like) domains and a cytoplasmic tail that is highly conserved among mammalian species. CD19 can form multimolecular complexes with CD21 and CD81, but forming these complexes is not required for CD19 signal transduction. Mutations on CD19 are associated with severe immunodeficiency syndromes. CD19 is highly expressed on B cell cancers such as B cell lymphomas, acute lymphoblastic leukemia, and chronic lymphocytic leukemia.
