靶标

  • 功能Assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
  • 疾病相关Defects in CD19 are the cause of immunodeficiency common variable type 3 (CVID3) [MIM:613493]; also called antibody deficiency due to CD19 defect. CVID3 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B cells is usually in the normal range, but can be low.
  • 序列相似性Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
  • 翻译后修饰Phosphorylated on serine and threonine upon DNA damage, probably by ATM or ATR. Phosphorylated on tyrosine following B-cell activation.
  • 细胞定位Membrane.

Anti-CD19 antibody 图像

  • CD19 was immunoprecipitated using 0.5mg Ramos whole cell extract, 5µg of Rabbit polyclonal to CD19 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Ramos whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab76591.

    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

    Band: 61kDa; CD19

  • Anti-CD19 antibody (ab76591) at 1/60 dilution + Jurkat cell line lysates at 35 µg

    Predicted band size : 61 kDa
    Observed band size : 61 kDa
    Additional bands at : 95 kDa. We are unsure as to the identity of these extra bands.
  • All lanes : Anti-CD19 antibody (ab76591) at 1/50 dilution

    Lane 1 : Non transfected 293 cell lysates
    Lane 2 : CD19 transfected 293 cell lysates

    Lysates/proteins at 2 µg per lane.


    Predicted band size : 61 kDa
    Observed band size : 95 kDa (why is the actual band size different from the predicted?)
