Ere propagated or constructed in our laboratory. HUVEC cells were purchased from ATCC (Manassas, VA, USA). New Zealand white rabbits were purchased from Experimental Animal Center of Hangzhou Normal University (China, SCXK (Zhe) 2010-0047). For experiments involving animals, approval was obtained from the Institutional Review Committee of Hangzhou Normal University. High fat diets were purchased from Xietong Medical Biological Engineering Limited Liability Company (Jiangsu, China). The cell culture medium sf-900 for insect cells, mammalian cell culture medium DMEM, Hanks buffer and fetal bovine serum (FBS), complete and incomplete Freund’s adjuvant were purchased from Gibco (Grand Island, NY, USA). Ni-NTA Purification System was sourced from Invitrogen (Carlsbad, CA, USA). LDL was purchased from Calbiochem-Merck (KGaA, Darmstadt, Germany). The Mouse 66His-tag monoclonal antibody, Cell Death Detection ELISA kit and Cell Proliferation ELISA kit were purchased from Roche (Mannheim, Germany). Horseradish peroxidase (HRP)-conjuagated goat-anti-mouse-IgG antibody and goat-anti-rabbit-IgG antibody were purchased from Beijing Dingguo Biotechnology Company (Beijing, China). The 8isoprostane EIA kit was purchased from Cayman chemical (Ann Arbor, MI, USA). Monoclonal antibodies anti-phospho-p38 MAP kinase (phospho-p38), anti-p38 MAP kinase, anti-JNK MAP kinase (phospho-JNK) and anti-JNK MAP kinase were purchased from Cell Signaling Technology Company (Beverly, MA, USA). The protein A sepharose CL-4B column and enhanced chemiluminescence (ECL) detection system were purchased from Amersham Pharmacia Biotech (Piscataway, NY, USA). The Malondialdehyde (MDA) detection kit, kits of total cholesterol (TC), 1315463 total triglyceride (TG), LDL and high density lipoprotein (HDL) and oil red O stain were purchased from Jiancheng Science and Technology Limited Company (Nanjing, China). Other reagents were purchased from Sigma (St. Louis, MO, USA).Preparation of LY-2409021 Polyclonal AntibodiesEscherichia coli BL21 (DE3) was transformed with the the recombinant prokaryotic expression Eliglustat web vector pET-28a-30Kc6 and was cultured in LB media with 50 mg/mL kanamycin, at 37uC until the OD600 reached approximately 0.5. Recombinant protein expression was induced with 1 mmol/L IPTG for 4 h. The Histagged fusion protein was extracted from the bacteria and purified by Ni2+-affinity chromatography. The purified protein was subsequently concentrated and desalted by dialysis. After thrombin digestion, 30Kc6 was released from the fusion protein. Then the protein was analyzed following the method of Bradford. A primary immunization of 0.5 mg/rabbit of 30Kc6 protein with Complete Freund’s Adjuvant (1:1) was administered to male New Zealand white rabbits on day 0. Boost immunizations of 0.5 mg 30Kc6 protein with Incomplete Freund’s Adjuvant were administered on days 21. After boosted 3 times with 30Kc6 protein, the blood were collected and centrifuged at 4uC 10, 000 g for 10 minutes, pipetted off the supernatant to obtain the antiserum, stored at 220uC. Columns containing 10 ml of packed protein A sepharose CL-4B were used to purify the polyclonal antibody. An ELISA was utilized to determine the polyclonal antibody titer and the specificity of the polyclonal antibody was detected by Western blot analysis with purified 30Kc6 protein.Induction of Apoptosis in HUVECLDL was placed into the dialysis bag with proper diameter and was incubated with PBS for 24 h at 4uC. The CuSO4 was added into the PBS solut.Ere propagated or constructed in our laboratory. HUVEC cells were purchased from ATCC (Manassas, VA, USA).
