Background

CD68, also called Lamp-4 in humans or macrosialin in mice, is a highly glycosylated type I transmembrane protein that belongs to the lysosome associated membrane protein (LAMP) family (1). CD68 expression is increased in cells associated with elevated phagocytic and degradative activity. High CD68 expression is detected in cells of the mononuclear phagocyte lineage including macrophages, osteoclasts, and myeloid dendritic cells (2). CD68 is a marker of activated microglia and only expressed at low levels in resting microglia (3). Staining for CD68 is predominantly intracellular, only 10 -15% of it is found on the cell surface. In oncology research, CD68 is the major biomarker for quantification of tumor-associated macrophages (TAMs) (4). High infiltration of CD68+ macrophages is an independent prognostic factor for overall survival in several tumor entities (5).

Cat. No. HS-460 003	50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Albumin and azide were added for stabilization. For reconstitution add 50 µl H₂O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications	WB: 1 : 1000 (AP staining) gallery IP: not tested yet ICC: not tested yet IHC: 1 : 2000 up to 1 : 5000 (see remarks) gallery IHC-P: 1 : 1000 up to 1 : 4000 gallery 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.
