Scientific Data Images for SR-BI Antibody
Western Blot: SR-BI Antibody [NBP2-99690]
Western Blot: SR-BI Antibody [NBP2-99690] - Anti-SR-BI rabbit polyclonal antibody at 1:500 dilution. Lane A: HepG2 Whole Cell Lysate. Lysates/proteins at 30 ug per lane. Secondary Goat Anti- Rabbit IgG H&L (Dylight 800) at 1/10000 dilution. Developed using the Odyssey technique. Performed under reducing conditions. Predicted band size: 60 kDa. Observed band size: 81 kDa (We are unsure as to the identity of these extra bands).Immunocytochemistry/ Immunofluorescence: SR-BI Antibody [NBP2-99690]
Immunocytochemistry/Immunofluorescence: SR-BI Antibody [NBP2-99690] - Immunofluorescence staining of SR-BI in HeLa cells. Cells were fixed with 4% PFA, permeabilzed with 0.3% Triton X-100 in PBS, blocked with 10% serum, and incubated with rabbit anti-human SR-BI polyclonal antibody (1:5000) at 4C overnight. Then cells were stained with the Alexa Fluor(R)488-conjugated Goat Anti-rabbit IgG Secondary antibody (green) and counterstained with DAPI (blue). Positive staining was localized to cell membrane and cytoplasm.Immunoprecipitation: SR-BI Antibody [NBP2-99690]
Immunoprecipitation: SR-BI Antibody [NBP2-99690] - SR-BI was immunoprecipitated using: Lane A: 0.5 mg Hela Whole Cell Lysate. Lane B: 0.5 mg HepG2 Whole Cell Lysate. 1 ul anti-SR-BI rabbit polyclonal antibody and 15 ul of 50 % Protein G agarose. Primary antibody: Anti-SR-BI rabbit polyclonal antibody, at 1:500 dilution. Secondary antibody: Dylight 800-labeled antibody to rabbit IgG (H+L), at 1:5000 dilution. Developed using the Odyssey technique. Performed under reducing conditions. Predicted band size: 60 kDa. Observed band size: 81 kDaApplications for SR-BI Antibody

Background: SR-BI
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.
