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. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD19 antibody [EPR23174-145] (ab245235)This image is courtesy of an anonymous AbreviewImmunohistochemistry analysis (Formalin/PFA-fixed paraffin-embedded sections) of paraformaldehyde fixed mouse spleen tissue. Stained with ab245235 at 1/1000 dilution. Secondary antibody used was Dako EnVision+ System- HRP Labelled Polymer Anti-R. Blocking was done with 5% serum for 1 hour at 21°C. The sample was incubated with the primary antibody and 5% Normal Goat Serum for 19 hours at 4°C. Antigen retrieval method was heat mediated Tris/EDTA pH 9.0.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of mouse spleen labelling LY6C with ab317272 at 1/100 (B), CD11b with ab133357 at 1/20000 dilution (C) and CD19 with ab245235 at 1/1000 dilution (D). Opal Polymer HRP Ms + Rb was used as a secondary antibody, and DAPI was used for a nuclear counter stain. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.
Panel A: merged staining of anti-LY6C (green; Opal™690), anti-CD11b (magenta; Opal™570) and anti-CD19 (yellow; Opal™520) on mouse spleen.
Panel B: anti-LY6C stained on monocytes/macrophages.
Panel C: anti-CD11b stained on monocytes/macrophages.
Panel D: anti-CD19 stained on B cells.
Co-staining of LY6C and CD11b can be observed.The section was incubated in three rounds of staining: in the order of ab317272, ab133357, and ab245235 for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.
The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope. -

Positive staining on mouse spleen. is observed. The nuclear counterstain was DAPI (Blue).
Secondary antibody control: Secondary antibody is ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) at 1000 dilution.
Heat mediated antigen retrieval using sodium citrate buffer (10mM citrate pH 6.0 + 0.05% Tween-20).

The expression profile/ molecular weight observed is consistent with what has been described in the literature (PMID: 26516065).
Negative control: CTLL-2 (PMID: 1370948) is treated as a negative cell line according to the literature, that CD19 is a B lymphocyte cell-surface marker that is expressed early during pre-B-cell differentiation, not in T cells.
