Western Blot: SR-BI Antibody [NB400-113]

Western Blot: SR-BI Antibody [NB400-113]

Western Blot: SR-BI Antibody [NB400-113] - Detection of SR-BI (80kDa) in mouse testis lysate total protein using NB400-113.
Immunocytochemistry/ Immunofluorescence: SR-BI Antibody [NB400-113]

Immunocytochemistry/ Immunofluorescence: SR-BI Antibody [NB400-113]

Immunocytochemistry/Immunofluorescence: SR-BI Antibody [NB400-113] - Antibody was tested in HeLa cells with DyLight 488 (green). Nuclei and alpha-tubulin were counterstained with DAPI (blue) and DyLight 550 (red).
Immunohistochemistry-Paraffin: SR-BI Antibody [NB400-113]

Immunohistochemistry-Paraffin: SR-BI Antibody [NB400-113]

Immunohistochemistry-Paraffin: SR-BI Antibody [NB400-113] - Analysis of a FFPE section of human adrenal gland tissue using 1:100 dilution of SR-BI antibody. The staining was developed using HRP-DAB based detection method and the nuclei of the cells were counterstained with hematoxylin. This antibody generated a specific staining of SR-BI/SCARB1 in the glandular cells. The staining was membrane-cytoplasmic in the zona glomerulosa cells while the signal was primarily localized to the membranes of the cells in the zona fasciculata and zona reticularis layers of the adrenal cortex.

Background: SR-BI

SR-BI (scavenger receptor class B member 1, SCARB1) belongs to the CD36 family and acts as a cell surface lipoprotein receptor for a variety of ligands including high density lipoprotein (HDL), phospholipids, phosphatidylserine, and lipoproteins such as lipopolysaccharide (LPS). SR-BI mediates selective uptake of HDL cholesteryl (HDL-C) ester in the liver, steroidogenic tissues, and adipose tissue and facilitates the flux of free and esterified cholesterol between the cell surface and apoB-containing lipoproteins and modified lipoproteins. SR-BI plays a role in antigen capture and cross-presentation from bacteria, parasites, and viruses such as Hepatitis C. In endothelial cells and macrophages, SR-BI is involved in anti-inflammatory and pro-survival signaling, providing protection against atherosclerosis and clearing apoptotic cells (efferocytosis) (1, 2).

At least 5 different human splice variants have been identified with theoretical molecular weights ranging from 60.9 kDa for the canonical sequence to 45 kDa for an N-terminally truncated variant (SR-BII) (3). The extracellular domain of human SR-BI (CLA-1) shares 80%, 80%, 89%, 86% and 84% aa sequence identity with mouse, rat, porcine, rabbit, and bovine SR-BI, respectively. SR-BI is highly glycosylated and removal of N-linked glycosylation reduces lipid transport.
