CD4 antibody | 44.38
Mouse anti Sheep CD4 antibody, clone 44.38 (MCA2213GA) used for the detection of CD4 expressing cells in lymphoid tissues by immunofluorescence microscopy.
Image caption:
Distribution of ovine NKp46+ cells in lymph nodes and mucosal surfaces. Sections from ovine pre-scapular lymph node (A - cortex and B - medullary zone), abomasum (C), duodenum (D), ileum (E), colon (F), uterus (G) and lung (H). NKp46+ cells: green; B-cells (IgM+) red; CD4+ T-cells blue in panel A and B; Epithelial cells (E-cadherin+) blue in parts C-H. White arrows: individual NKp46+ cells. Red arrows: putative intra-epithelial NKp46+ cells. "Fo": follicle and "P": paracortex. "L": lymphocytic aggregate. Isotype matched controls demonstrated diffuse and dull background fluorescence in both the red and green channels (data not shown), however this could easily be distinguished by character and/or intensity from the bright cell-surface staining seen with the NKp46 and IgM-specific antibodies. Autofluorescent artifacts such as those demonstrated by the yellow arrows (e.g. in C and D) were not uncommon in the tissues examined. A scale for each of the figure parts is given. Images are taken from tissues that were representative of samples taken from a minimum of three animals as determined by preliminary single colour immuncytochemistry analysis.

Mouse anti Sheep CD4 antibody, clone 44.38 (MCA2213GA) used for the evaluation of CD4 expression on ovine peripheral blood mononuclear cells by flow cytometry.
Image caption:
Analysis of the phenotype of ovine NKp46+ populations. (A)Two-colour flow cytometry analysis of ovine PBMC co-stained with EC1.1 and a selection of monoclonal antibodies against CD2, CD4, CD8, CD11b, CD16, WC1, IgM and MHCII. WC1 and IgM are surface molecules expressed by subsets of γδ T-cells and B-cells respectively. (B) Perforin expression by NKp46+ PBMC. Cells expressing NKp46 were stained with anti-perforin monoclonal antibody (solid line) or an isotype control (broken line). (C) Two-colour flow cytometry analysis of mesenteric and pre-scapular lymph nodes and the spleen cell populations co-stained with EC1.1 and monoclonal antibodies against CD2 and CD8. The results shown are representative of the results obtained from a minimum of five animals.

Phycoerythrin conjugated Mouse anti Bovine CD4 antibody, clone 44.38 (MCA2213PE) used for the evaluation of CD4 expression on ovine peritoneal cells by flow cytometry.
Image caption:
Percentage of cell populations in the peritoneal fluid during the early stages of infection. The specific cell populations are shown as follows: (a) TCD4; (b) TCD8; (c) WC1+γδ; (d) CD14; (e) MHCII; (f) CD83. Cell subsets of uninfected (Neg. Ctl) and infected sheep (Group 1) are shown in columns. Mann-Whitney U-test was used to compare data from Groups 1 and 3. Values represent the mean ± standard deviation (SD). Asterisks indicate different levels of significance between groups: *P ≤ 0.05, **P ≤ 0.01
