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.

Immunohistochemistry on fresh frozen (IHC-Fr) cryo-tissue-sections. In contrast to standard PFA perfusion fixed tissues, fresh frozen cryo-tissue-sections can be variably postfixed with alcohols, acetone or PFA. Alcohol or acetone fixation is e.g. of advantage for antigens masked by PFA crosslinking. For recommended postfixation, please refer to the ”Remarks” section. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Immunogen Synthetic peptide corresponding to residues near the amino terminus of human Galectin-3 (UniProt Id: P17931)
Reactivity Reacts with: human (P17931).
No signal: mouse (P16110).
Other species not tested yet.
Remarks

ICC: 4% formaldehyde/PFA fixation is recommended.

Fluorescent double staining for Galectin-3 (green) and IBA1 (red) in a human small intestine

Background

Galectin-3 (Gal-3, Mac-2) is a β-galactoside binding protein that is predominantly located in the cytoplasm and shuttles into the nucleus. In addition, it is secreted to the cell surface and into biological fluids. Depending on its localization, it exerts pleiotropic biological functions like cell growth, cell differentiation, inflammation, fibrogenesis, migration, apoptosis, and host defense (1). It is also involved in cancer pathogenesis, proliferation, and spreading of metastasis (2). Galectin-3 is highly expressed in the covering epithelia of the digestive tract and the urinary system (3) and plays important roles in the organization of renal and intestinal cells. Furthermore, Galectin-3 has been identified in a variety of other cell types including fibroblasts, keratinocytes, granulocytes, dendritic cells, and macrophages (2). Galectin-3 is expressed by certain tissue-resident macrophages such as Kupffer cells in the liver, red pulp macrophages in the spleen, and alveolar macrophages in the lung (3). In the brain, Galectin-3 is abundant in activated microglia but not expressed in resting cells. Following brain injury, Galectin-3 triggers anti-inflammatory properties of microglia (4). In Alzheimer’s disease, Gal-3 expression is strictly associated with microglial cell activation around Aβ plaques. In stroke, Gal-3 was found to be expressed primarily in proinflammatory microglial cells (5).
