CD45R antibody | RA3-6B2
Rat anti Mouse CD45R antibody, clone RA3-6B2 (MCA1258) used for the enumeration of B cells in the intestinal mucosa by immunofluorescence.
Image caption:
Recruitment of inflammatory cells in the intestine of neonates after CpG-ODN treatment. Eight-day-old neonatal mice received 20 μg/g of CpG-ODN orally. Twenty-four hours after treatment, ilea were removed to analyze the recruitment of inflammatory cells by immunohistochemistry. Six to ten neonates from different litters (5 sections for each animal) per group were analyzed. Data were analyzed by non-parametric Mann-Whitney test.

Rat anti Mouse CD45R antibody, clone RA3-6B2 (MCA1258G) used for the identification of marginal zone B cells in mouse spleen by immunofluorescence on cryostat sections.
Image caption:
Intrafollicular location of MZB cells in B6.TC spleens. A. Representative spleen sections from 3 mo old B6.TC (left) and B6 (right) mice stained with Moma-1-FITC, CD1d-PE and B220-PB. The B220+ CD1d+ MZB cells show as bright pink while the other B cells show as blue. The ring of Moma-1+ metallophillic macrophages delineates the MZ inner edge. B. Percentage of CD1d+ B220+ B cells relative to total B220+ B cells outside (MZ) and inside (FO) the Moma-1+ ring in 3 mo and 10 mo old B6 and B6.TC mice. The data show means and standard errors of the mean (SEM) calculated of 4 MZ and FO areas for each mouse. ***: p < 0.001 for t tests. C. Representative spleen sections from 10 mo old B6.TC (left) and B6 (right) mice stained with CD4-FITC, CD1d-PE and B220-PB. Boxed areas show multiple contacts between green B6.TC CD4 T cells and pink MZB cells, but not in the B6 spleen. Original magnification: 200X.
