Detection of CXCR5 antibody in CD19+ Human PBMCs antibody by Flow Cytometry.

Detection of CXCR5 in CD19+ Human PBMCs by Flow Cytometry.

Human peripheral blood mononuclear cells (PBMCs) were stained with Mouse Anti-Human CD19 APC-conjugated Monoclonal Antibody (Catalog # FAB4867A) and either (A) Mouse Anti-Human CXCR5 Monoclonal Antibody (Catalog # MAB190) or (B) Mouse IgG2B control antibody (Catalog # MAB0041) followed by anti-Mouse IgG PE-conjugated secondary antibody (Catalog # F0102B).

CXCR5 antibody in Human PBMCs by Immunocytochemistry (ICC).

CXCR5 in Human PBMCs.

CXCR5 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Mouse Anti-Human CXCR5 Monoclonal Antibody (Catalog # MAB190) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 637-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL008) and counterstained with DAPI (blue).

CXCR5 antibody in Human Kidney by Immunohistochemistry (IHC-P).

CXCR5 in Human Kidney.

CXCR5 was detected in immersion fixed paraffin-embedded sections of human kidney using Mouse Anti-Human CXCR5 Monoclonal Antibody (Catalog # MAB190) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cell membranes.

Chemotaxis Induced by CXCL13/BLC/BCA‑1 and Neutralization by Human CXCR5 Antibody.

Chemotaxis Induced by CXCL13/BLC/BCA‑1 and Neutralization by Human CXCR5 Antibody.

Recombinant Human CXCL13/BLC/BCA-1 (Catalog # 801-CX) chemoattracts the BaF3 mouse pro-B cell line transfected with human CXCR5 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CXCL13/BLC/BCA-1 (0.05 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CXCR5 Monoclonal Antibody (Catalog # MAB190). The ND50 is typically 0.25-1.5 µg/mL.
Detection of Human CXCR5 by Western Blot

Detection of Human CXCR5 by Western Blot

Inverse correlation between p53 and CXCR5 expression and function in MCF-7 cells.(A) p53 knock-down results in an increase in the relative abundance of CXCR5 mRNA. The result of 10 experiments is shown. (B) Changes in p53 and CXCR5 protein levels correlate with the levels of corresponding mRNAs. mRNA levels were measured by RT-PCR in real time. Representative data are shown, the experiment was repeated 2 times for p53 and 3 times for CXCR5. Complete western blots are shown in Supplementary Figure S1. (C) CXCR5 stimulates of c-Jun mRNA expression in MCF-7 cells in p53-dependent manner. Cells were exposed to recombinant CXCL13 for 6 hours prior to RNA isolation. The result of three experiments is shown. *P < 0,01 versus MCF-7.
