T Lymphocytes antibody | KEN-5
Mouse anti Rabbit T lymphocytes antibody, clone KEN-5 (MCA800G) used to assess CD5 expression levels on rabbit mononuclear cells by flow cytometry.
Image caption:
Analysis of in vivo BrdU incorporation.
Rabbits were treated as described in Fig. 1. PBMCs were collected at days 11, 15, 17, 20 and 24 post-inoculation, while mononuclear cells were isolated from popliteal lymph node and spleen at the time of death. Cells were labelled with anti-CD11b, IgM, CD5, CD4 and CD8 mAbs as the primary antibodies. Alexa 633-GAM was used as the secondary antibody. In vivo BrdU incorporation was revealed by immunofluorescent staining as described in Methods. After staining, cells were analysed by flow cytometry. A. Representative flow cytometry dot plots are shown for each double staining, they illustrate the data obtained at day 17 post-infection for the PBMC of rabbits MR17/1 and IR17/1. The data represent the percentages of BrdU positive cells (y-axis) calculated based on the acquisition of 10,000 cells expressing the indicated cell marker (x-axis). B. The percentage of BrdU positive cells amongst the indicated cellular subset was determined and compared between AlHV-1 infected (left column: bold lines; middle and right columns: hatched bars) and mock infected (left column: dotted lines; middle and right columns: open bars) groups (* P<0.05; **P<0.005, *** P<0.0001). In the left column the following symbols were used: ▴, MR17/1 and IR17/1; ▭, MR17/2 and IR17/2; ●, MR20 and IR20; ○, MR24 and IR24.

Mouse anti Rabbit T lymphocytes, clone KEN-5, recognizes rabbit (lapine) T-cells. Clone KEN-5 recognizes >90% thymocytes and approximately 40-45% mesenteric lymph node cells and immunoprecipitates a ~67 kDa protein from rabbit thymocytes.
In contrast to humans and mice where only a very small population of B-cells express the CD5 antigen, the CD5 antigen in rabbits is widely expressed by peripheral blood B cells. However, the KEN-5 antibody, while originally reported as recognising rabbit CD5 (Kotani et al.1993), does not bind to rabbit CD5 transfectants. Furthermore, clone KEN-5, unlike other known antibodies recognizing rabbit CD5 and anti human cross reactive CD5 antibodies, shows very limited binding to rabbit B-cells, which in adult rabbits have been demonstrated to express CD5 (Raman & Knight 1992) More recently studies (Pospisil et al. 2009) indicate that clone KEN-5 may recognize a epitope that is dependant on glycosylation to maintain its structural configuration which may explain why this antibody does not recognize recombinant rabbit CD5 produced in insect cells which contain different glycans from those found in mammalian cells. It has therefore been suggested that KEN-5 may distinguish between different isoforms of CD5 in lapine T and B cells (Pospisil et al. 2009).
