SR-AI/MSR Antibody - BSA Free

Western Blot: SR-AI/MSR Antibody [NBP1-00092] - Detection of Macrophage Scavenger Receptor I (MSR1) protein in the lysate of human liver.

Immunocytochemistry/Immunofluorescence: SR-AI/MSR Antibody [NBP1-00092] - The MSR antibody was tested in Raw cells at a 1:250 dilution against DyLight 488 (Green). Alpha-tubulin and nuclei were counterstained against DyLight 550 (Red) and DAPI (Blue), respectively.

Immunohistochemistry-Frozen: SR-AI/MSR Antibody - BSA Free [NBP1-00092] - Immune labeling of non-parenchymal liver cell (NPC) cultures for selected SRs and C-type lectins. NPCs from the 25-45% interface on the Percoll gradient were incubated for 1 h, then fixed 15 min in 4% paraformaldehyde, and double immune-labeled with antibodies to Fc-gamma-RIIb2 (SE-1; red fluorescence; left column), or CD68 (red fluorescence; right column), and to either stabilin-2 (STAB2; green), mannose receptor (MRC1; green), SR-A1 (green), or SR-B1 (green). Overlap of green and red fluorescence is seen as yellow staining in the overlay images. Cell nuclei were stained with DAPI (blue). Image collected and cropped by CiteAb from the following publication (//pubmed.ncbi.nlm.nih.gov/33246411/) licensed under a CC-BY licence.

Flow Cytometry: SR-AI/MSR Antibody [NBP1-00092] - A surface stain was performed on Raw264.7 cells with SR-AI/MSR Antibody NBP1-00092R (blue) and a matched isotype control (orange). Cells were incubated in an antibody dilution of 5 ug/mL for 20 minutes at room temperature. Both antibodies were conjugated to DyLight 550.

Background

Macrophage Scavenger Receptor I (MSR1, also called CD204 or scavenger receptor A) belongs to scavenger receptor A family and represents phagocytic pattern-recognition receptors (PRRs) expressed predominantly on macrophages and dendritic cells. MSR1 is a single-pass type II membrane glycoprotein capable of binding to a wide range of polyanionic ligands (e.g., modified low density lipoproteins, pathogen-derived molecules), and is implicated in the pathologic deposition of cholesterol in arterial walls during atherogenesis, innate immune response as well as Alzheimer's disease. MSR1 mediates the endocytosis of a diverse group of macromolecules including modified LDLs, and scavenger receptors MSR1, CD36 and LOX-1 are three main receptors for oxidized LDL on macrophage membrane wherein MSR1/CD36 account for more than 9/10 of the lipid accumulation in macrophages exposed to oxidized LDL. Defects in MSR1 have also been linked to prostate cancer and Barrett esophagus (BE).
