Figure Lengend Snippet: A. Quantitative RT-PCR analysis of Irf-4 , Blimp-1 , Ddit3 , and Cxcr4 mRNA expression in 589 untreated cells and following 72 hours of LPS treatment. Values were normalized to Gapd mRNA, and error bars represent PCR triplicates. Significance was determined using a one-tailed Student’s t-test (*p<0.05; **p<0.01; ***p<0.001; ****p<0.0001; NS = not significant). B. Densitometry values representing the percentage of spliced/unspliced (s/u) Xbp-1 in 589 BzS, BzR and I-BzR cells untreated or treated with LPS for 72 hours. C. Quantitative RT-PCR analysis of Cd69 mRNA expression in 589 untreated cells and 72 hour LPS-treated cells. Values were normalized to Gapd mRNA and error bars represent PCR triplicates. Significance was determined using a one-tailed Student’s t-test (*p<0.05; ***p<0.001). D. Fluorescence-activated cell sorting analysis of untreated (solid black line) BzS (top panel), BzR (middle panel), or I-BzR (bottom panel) and LPS-treated (dotted lines) cells stained for CD69 protein expression.
Article Snippet: Cells were stained with the following anti-mouse antibodies: CD184/Cxcr4 PE (clone 2B11, also used for anti-human Cxcr4), CD69 FITC (clone H1.2F3), CD93 APC (clone AA4.1), CD20 PE (clone AISB12), CD22 FITC (clone 2D6), CD27 FITC (clone LG.7F9) (all from eBioscience, San Diego, CA), CD138/syndecan-1 PE (clone 281-2), CD19 PE (clone 1D3), B220 APC (clone RA3-6B2) (all from BD Biosciences, Franklin Lakes, NJ), IgM-FITC (SouthernBiotech, Birmingham, AL), CD38 (BioLegend, San Diego, CA) and analyzed using the FACSCalibur (BD Biosciences, Franklin Lakes, NJ).
