Background

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.

FAQs for SR-BI Antibody (NB400-104). (Showing 1 - 4 of 4 FAQs).

  1. Would you please help us to confirm the application of NB400-101? Can this antibody be used for IHC-P or IHC-Fr? If yes, what is the dilution for the two application? The customer finds that NB400-104 and NB400-101 have the same immunogen, but the molecular band is not the same, they are approx. 82kDa and approx. 75kDa separately. We are confused with this and would you please tell us the dilution for NB400-104 in IHC-P detection?
    • Both NB400-100 and NB400104 can be used with IHC paraffin embedded sections at 2.5-5 ug/ml. With regards to the WB image, since the markers are different on those gels, a 5 kDa difference between markers would not be out of the range of possibility but as far as the immunogen is concerned, both antibodies share the same region, meanwhile please keep in mind that NB400-104 can be used in human, mouse and rat tissues but NB400-101 can only be used in human and mouse.
  2. What is the difference between NB400-101 and NB400-104? The same IF image is shown on both product pages, so which antibody was really used?
    • Regarding your inquiry, NB400-101 and NB400-104 are the same antibodies and the reason why they have different catalog numbers is, in the first stage of production one of these antibodies was purified and the other was not but now both are purified and the same.
  3. Do the cells have to be permeabilized before using this antibody for flow cytometry?
    • For flow cytometry, we do recommend fixation and permeabilization of the cell prior to incubation with this antibody. The product NB400-104 recognizes an epitope in the cytoplasmic domain of this membrane protein. Usually our lab will recommend using 0.1-0.5% Tween-20 for membrane permeabilization. Sometimes, you can also achieve ample permeabilization of the membrane using methanol fixation. Our lab's flow protocol can be found here: Flow Cytometry protocol.
  4. Hi. I'm interested in scarb1 antibody. Can you tell me what is the difference between NB400-101 and 104?
    • SR-BI antibody NB400-101 has been validated for Block/Neutralize, while NB400-104 has not been.
