(A) B cells are important for expression of pro-angiogenic genes within human prostate tumor tissues. The density of B cells around tumor vasculature in prostate tumor tissue was determined by immunofluorescent staining using anti-CD19 and anti-CD31 antibodies (top); scale bars, 20 μm. Real-time RT-PCR measuring RNA expression levels of pro-angiogenic genes in the consecutive human prostate tumor tissue sections (bottom). The relative amount of mRNA is normalized to 18S and compared to RNA levels in tumor tissues with high p-STAT3, which is designated as 1; means ± SD, n = 2.

Antibody Quality and 
Unrivaled 
| Mouse anti Human CD19 antibody, clone LT19 recognizes human CD19 also known as T-cell surface antigen Leu-12 or B-lymphocyte surface antigen B4. CD19 is a ~95 kDa type I single pass transmembrane glycoprotein expressed on follicular dendritic cells and B-cells during maturation but is lost on development into plasma cells (de Rie et al. 1989). CD19 is the broadest lineage specific marker for B cells and functions as a B-cell co-receptor in conjunction with CD21 (Bradbury et al. 1992), CD9, CD81 and CD82 (Horváth et al. 1998). CD19 is implicated in the down-regulation of B cell growth and proliferation (Pezzutto et al. 1987). |
