Knockout Validated: SR-BI Antibody - BSA Free [NB400-101]

Knockout Validated: SR-BI Antibody - BSA Free [NB400-101]

Knockout Validated: SR-BI Antibody [NB400-101] - Immunofluorescent analysis of SR-BI localization in aorta of Tie2-Scarb1 x Scarb1-KO and Scarb1-KO mice. Mouse aorta sections were stained for SR-BI (a and d, red). In several EC stained for SR-B1 red color was present on both apical and basolateral sides. There is no red signal in aorta from Scarb1-KO mice.

Knockout Validated: SR-BI Antibody - BSA Free [NB400-101]

Knockout Validated: SR-BI Antibody [NB400-101] - Immunofluorescent analysis of SR-BI localization in liver of normal, Tie2-Scarb1 x Scarb1-KO, and Scarb1-KO mice. Liver sections from normal (b) and Tie2-Scarb1 x Scarb1-KO mice (c) were stained for SR-BI (red) and cytokeratin 8-18 (green).Merge image for normal mouse (b) demonstrates strong presence of SR-BI in hepatocytes (b, yellow signal) and absence of detectable level of SR-BI protein in liver of Tie2-Scarb1 x Scarb1-KO mice (c). In Scarb1-KO mice there was no detectable level of SR-BI protein (d, staining for SR-BI). Blue = DAPI.

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.
