CD169 antibody | 3B11/11
Mouse anti Porcine CD169 antibody, clone 3B11/11 (MCA2316GA) used for the evaluation of CD169 expression on porcine cells by flow cytometry and immunohistochemistry.
Image caption:
(A) MAb 1F1 and 3B11 recognize an antigen expressed in alveolar macrophages and MoDC. Cells were labeled with 1F1 or 3B11 mAb (black histograms) or with irrelevant isotype-matched mAb (grey histograms). Results are representative of five independent experiments. (B) In the spleen, staining with 1F1 (1) and 3B11 (2) mAb appears associated with the walls of the ellipsoidal vessels that surround the islands of white pulp. (C) In lymph nodes, the antigen was detected in the subcapsular sinus and medullary cords (1) and in the periphery of follicles and some follicular cells (2).

Mouse anti Porcine CD169 antibody, clone 3B11/11 (MCA2316) used for the evaluation of CD169 expression on porcine cells by western blotting and immunoprecipitation.
Image caption:
MAb 1F1 and 3B11 bind to two different epitopes on the Sn molecule. Black histograms show binding of labeled 3B11 or 1F1 mAb on alveolar macrophages after incubation with the indicated unlabeled antibodies. Grey histograms correspond to the negative control staining. Results are representative of at least two independent experiments using cells from different animals.

| Mouse anti Pig CD169, clone 3B11/11 recognizes porcine CD169, also known as sialoadhesin or Siglec-1, a member of the sialic acid binding immunoglobulin-like lectin (Siglec) family. CD169 was originally identified in mice and identified as the sialic acid dependent Sheep erythrocyte receptor (Crocker et al.1986). CD169 has subsequently been identified in rat (van den Berg et al. 1992), human (Mucklow et al. 1995) and pig (Vanderheijden et al. 2003) . Mouse anti Porcine CD169, clone 3B1/11 was originally raised as part of a panel of anti porcine macrophage monoclonal antibodies raised against isolated porcine alveolar macrophages (Bullido et al. 1997). Immunohistochemical analysis indicated restriction to macrophage populations mainly in the spleen, lymph nodes, liver and Peyer’s patches. Originally described as a non phagocytic intercellular adhesion receptor, work on porcine CD169 indicated that it may play a role as a viral adhesion receptor (Delputte et al. 2006) and as a targeted receptor for the delivery of toxins and antigens (Delputte et al. 2011) . Mouse anti pig CD169, clone 3B11/11 detects a band of approximately 190 kDa in alveolar macrophage extracts under non-reducing conditions (Revilla et al 2009). |
