  • 描述
    小鼠单克隆抗体[A3-B1] to CD19 (FITC)
  • 偶联物FITC. Ex: 493nm, Em: 528nm
  • 特异性ab91155 is B lineage-specific and reacts with early B-cell precursors, pre-pre-B-cells, pre-B- cells, B-cells, intermediate B-cells, mature B-cells and some plasmacytoid cells. Plasma cells were found to be negative. This antibody does not react with other haemopoïetic cells. The antibody also reacts with pre-B-cell- lines, B lymphoblastoid cell-lines and Burkitt cell- lines, and with 50% of myeloma cell-lines. Virtually all non T-ALL, B-CLL and B-cell lymphomas were found to be positive, myeloma cells were found to be negative.

  • 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.

    Application Flow Cytometry
    Sample Monkey Cell (cryopreserved PBMC)
    Specification cryopreserved PBMC
    Preparation Cell harvesting/tissue preparation method: cells were thawed and washed in RPMI with 10% FCS plus Pen/Strep. Cells were counted using Trypan blue. Cells were transferred into FACS tubes and washed with DPBS. Antibodies were added and cells were stained for 30 min in the dark at RT. As positive control human PBMC were included.
    Sample buffer: DPBS during staining, DPBS plus 2% Formaldehyde
    Fixation Formaldehyde
    Permeabilization No
    Gating Strategy Cells were gated on Lymphocytes (SSC/FSC) followed by CD3/CD14 negative gating followed by CD19 positive, Isotype or CD20 as alternative control
