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 (NB400-113). (Showing 1 - 5 of 5 FAQs).

  1. Do you have information on epitope of NB400-113?
    • NB400-113 is not epitope mapped and was generating by using an immunogen of full-length mouse SR-BI expressed by adenovirus
  2. Is this Ab identical to the former Ab3811 - Ab 3811 was used by Liisanantti et al. (Alcoholism: Clinical and Experimental Research 2009) is the Ab3811 still available?
    • Yes, Ab3811 from Abcam and the antibody NB400-113 from Novus are one and the same. The Abcam catalog number is our antibody that they are distributing. NB400-113 should perform as indicated in the literature under Ab3811.
  3. Could you please give me information about the molecular weight of SR-BI-antibody (NB400-113)?
    • Encoded by gene SCARB1, SR-BI is a plasma membrane receptor for high density lipoprotein cholesterol (HDL) and its expected molecular weight is 61kD. However, this protein undergoes post-translational modifications including N-glycosylation which causes a significant increase in the molecular mass from 61kD to up to approximately 82kD.
  4. We are interested in using this antibody to perform staining on cells and to detect cells with FACS (flow cytometry). It is indicated on the datasheet that it is possible to use this antibody for flow cytometry, however little information is provided. Could you please inform us on the isotype of the antibody and the concentration we need to use for our FACS experiments?
    • This antibody is a rabbit polyclonal, so the isotype is IgG. We have never tested in-house for flow cytometry. This antibody has been validated for use in Flow Cytometry by other researchers in publications. All the information we have regarding its use in flow cytometry comes from the publications on the datasheet (PMID: 20041149 and 22622498). We recommend 1:50-1:200 for ICC, so this is probably a good range to start your testing with.
  5. Please provide an estimated concentration for NB400-113 Lot G7?
    • As mentioned on the datasheet, this product is an unpurified formulation (whole antiserum) and the exact concentration of antibody is not quantifiable.However, the concentration of antibody in antisera can vary from 1-10 mg/ml.
