- Description
- Description: The 8A7 monoclonal antibody reacts with the human BAFF receptor, also known as B lymphocyte stimulator (BLyS protein) receptor, which is expressed on B cells. The ligand for this receptor, BAFF (B cell-activating factor of the TNF family) is a B cell survival factor and regulates CD21/35 and CD23 expression. Interaction of this ligand with its receptor causes elevated CD21/35 and CD23 expression, whereas receptor blockade has been shown to down-modulate expression. Applications Reported: This 8A7 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 8A7 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.015 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered.

- Fig. 3 The expression of BAFF receptors by human mesangial cells. a Total RNA was extracted from human mesangial cells and analyzed for expression of BAFF-R, TACI, BCMA and BAFF, normalized to GAPDH expression, by real-time PCR. b The presence of BAFF-R on the surface of human mesangial cells was detected with BAFF-R antibody by flow cytometry. Background signal is presented as a gray line, and BAFF-R signal is presented as a blue line. c Cytosolic protein fraction (indicated as c) and membrane protein fraction (indicated as m) were prepared from human mesangial cells and subjected to western blot analysis. Whole protein lysate of activated human CD19 + B cells was loaded as a positive control for expression of BAFF-R. Na + /K + -ATPase and Erk kinase represented membrane and cytosolic proteins respectively

Mean MFI of BR3 on peripheral B lymphocytes in GD patients was 4.52 +- 2.06, higher than that in HC (3.00 +- 0.87), P = 0.0015; BR3 expression in HT patients was not increased; b : Trend of decreased TACI expression on peripheral B lymphocytes in GD patients. Mean MFI of TACI on peripheral B lymphocytes in GD patients was 7.96 +- 4.06, lower than that in HC (9.10 +- 3.37) without significance, P = 0.1285. TACI expression in HT was not decreased. MFI: mean fluorescence intensity. Bars: mean MFI. ns: not significant; **: vs. HC, P < 0.01

- Figure 4 BAFF-R expressing B cells at different maturational stages are present in decidua. To identify lymphocytes, in the first panel to the far left, live cells were gated using a viability dye that marks all dead cells and the lymphocyte gate was then set within CD45-expressing singlet leukocytes. (a - c) Within lymphocytes, CD56 + NK cells, CD3 + CD56 neg T cells, CD3 + CD56 + NK-T-like cells and CD19 + CD20 + B cells were identified (second and third panels). B cell maturational stages were distinguished based on CD24 and CD38 expression (fourth panel). The BAFF-R expression on the different lymphocyte populations is depicted to the far right. (d) The proportion of different cell subsets with in the lymphocyte gate and (e) the proportion of B cells at different maturational stages isolated from decidua basalis, decidua parietalis and cord blood. (f) The mean fluorescence intensity of BAFF on B cells at different maturational stages. Floating bars show minimum to maximum values, and horizontal bar indicates the median (n = 3). Approximately 40.000 cells were collected in the lymphocyte gate for d. basalis and CBMC and 20.000 for d. parietalis.
