Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Staining of human CD163 in human spleen with anti-human CD163 but no staining of mouse CD163 in mouse spleen

Background

CD163 is a member of the group B scavenger receptor cysteine-rich (SRCR) superfamily expressed on human and murine macrophages. CD163 is also expressed in human monocytes, but not in circulating mouse monocytes (1). CD163 expression is significantly induced by anti-inflammatory stimuli like glucocorticoids and dexamethasone. Inflammatory stimuli like interferon γ and LPS suppress CD163 expression in macrophages (2). In mice, CD163 is mainly expressed by tissue-resident macrophages including Kupffer cells of the liver, red pulp macrophages in the spleen, perivascular macrophages of the CNS (3), and bone-marrow resident macrophages (4), but not by classical bone-marrow derived macrophages (4). In malignant tumors in mice and humans, macrophage CD163-mediated induction of IL-6 promotes tumor development and progression (4). The pool of tumor-associated macrophages (TAMs) is composed of both newly recruited monocyte derived macrophages and resident macrophages (5). CD163-positive tissue-resident macrophages have been shown to play a specific role in the malignant spread of disseminated tumor cells and the development of invasive disease in a mouse model of metastatic ovarian cancer (1). CD163 is considered useful to distinguish CD163-positive resident macrophages from CD163-negative bone-marrow derived macrophages in mice (4).
