CD8 antibody | 4B11
Mouse antiHuman CD8 antibody, clone 4B11 (MCA1817) used for the identification of CD8 expressing cells in Buruli ulcer secondary lesions by immunohistochemistry on formalin fixed, paraffin embedded tissue sections.
Image caption:
Presence of B-cell clusters in the secondary lesions.
A: Band of CD20 positive B-cells in sections of ulcer 2 of patient 1. B–E: serial sections of nodule 3 of patient 2 with a small dense cluster of CD20 positive B-cells (B) surrounded by CD14 positive macrophages/monocytes (C) and few interspersed CD3 positive T-cells (D) from which the majority was CD8 negative (E). Higher magnification (F–I) revealed a very dense package of the B-cells.

Mouse anti Human CD8 antibody, clone 4B11 (MCA1817) used for the detection of CD8 expressing lymphocytes in OLP tissue by immunohistochemistry on formalin fixed, paraffin embedded tissue sections.
Image caption:
Presence of bacteria within epithelial cells CD3+, CD8+ and CD8− lymphocytes in OLP tissues.
Sections of OLP tissues (n = 4) were hybridized in situ for 16S rRNA and then immunostained for CD8 (H). Red arrows indicate bacteria detected within CD8+ cells; blue arrows indicate bacteria detected within CD8− lymphocytes; arrowheads indicate an immunologic synapse-like structure.

Image caption:
Increased infiltration of T cells correlated with the levels of bacteria in the lamina propria in OLP.
(A–D) Representative immunohistochemical detection of CD3+ cells (A), CD4+ cells (B), CD8+ cells (C), and macrophages (D) in control (n = 10) and OLP (n = 36) tissues. Each symbol in the graphs represents the mean intensity of stained signals per ROI measured in four randomly chosen fields (**P <0.01; ***P <0.001 by Mann-Whitney U test). (D) Correlation plots between the levels of bacteria in the lamina propria and the levels of CD3+ cells, CD4+ cells, CD8+ cells, or macrophages (r and P by Spearman's rank correlation test).

Mouse anti Human CD8 antibody, clone 4B11 recognizes the human CD8 cell surface antigen, a ~32 kDa glycoprotein expressed by the cytotoxic/suppressor subset of T-cells and weakly by NK cells. Mouse anti Human CD8 antibody, clone 4B11 was raised based on an earlier successful strategy used to generate rabbit polyclonal antibodies against human CD8 employing the same immunizing peptide (Mason et al. 1992).
Mouse anti Human CD8 antibody, clone 4B11 has been reported as being suitable for use in Western blotting (Williamson et al. 1998) .
