FITC conjugated Rat anti Mouse CD4 antibody, clone GK1.5 (MCA4635F) used to identify CD4 expressing cells in mouse spleen cryosections by immunofluorescence.
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.

| Rat anti Mouse CD4 antibody, clone GK1.5 recognizes mouse CD4, a ~55 kDa protein also known as Ly-4 and L3T4. CD4 is a single chain transmembraneous glycoprotein which belongs to the immunoglobulin superfamily, and is primarily expressed on T helper cells, peripheral blood monocytes and tissue macrophages. CD4 is also expressed on a subpopulation of regulatory T cells (CD4+ CD25+), which play a key role in the maintenance of self tolerance. Rat anti Mouse CD4 antibody, clone GK1.5 has been reported to block CD4+ T-cell activation. It blocks class II MHC antigen-specific binding, thereby inhibiting functions such as class II MHC antigen-specific proliferation and the release of lymphokines. It may also be used for in vivo and in vitro cell depletion of CD4+ T-cells. |
