Catalog no. 115-096-071) was purchased from Jackson ImmunoResearch Laboratories (West Grove, PA, USA). Horseradish peroxidase-labeled sheep anti-mouse immunoglobulins (IgGs) (no. NXA931) were obtained from GE Healthcare (Uppsala, Sweden). The antiphosphotyrosine (clone 4G10, no. 05-321) and the anti-p85 (no. 06-195) antibodies had been purchased from Upstate Biotechnology (Lake Placid, NY, USA). Monoclonal anti-flotillin-1 antibody (no. 610820) was purchased from BD Transduction Laboratories (Mississauga, ON, Canada). The mouse IgG2a isotype antibody (no. 0572) was purchased from Beckman Coulter (Mississauga, ON, Canada). Anti-CD11b antibody (OKM1, no. 88012702) was purchased from Sigma-Aldrich Canada (Oakville, ON, Canada), along with the anti-FPRL1 antibody was obtained from R D Systems (Minneapolis, MN, USA).Carboxy-PTIO In Vitro Sodium orthovanadate (Na3VO4), N6,2-O-dibutyryladenosine 3,5-cyclic monophosphate sodium salt (dibutyryl cyclic adenosine monophosphate (dibutyryl cAMP)), colchicine and Dextran T500 have been obtained from Sigma-Aldrich Canada.Hexanoylglycine Technical Information 3-[(3Cholamidopropyl)dimethylammonio]propanesulfonic acid (CHAPS), aprotinin and leupeptin have been purchased from Roche Applied Science (Laval, QC, Canada).PMID:23805407 The Western Lightning Chemiluminescence Plus ECL kit was obtained from PerkinElmer (Boston, MA, USA). Ficoll-Paque and 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) were obtained from Wisent (St-Bruno, QC, Canada). Protein A Sepharose was bought from GE Healthcare. Gelatin was obtained from Fisher Scientific (Nepean, ON, Canada). Fura-2-acetoxymethyl ester (Fura2AM) was obtained from Invitrogen (Burlington, ON, Canada), and also the triclinic MSU crystals were synthesized and characterized as previously described by Naccache et al. [14]. Endotoxin contamination was ruled out by Limulus amebocyte lysate assay. siGENOME SMARTpool MICL (no. D-021369-01) and siGENOME nontargeting smaller interfering RNA (siRNA) pool 1 (adverse control, no. D-001206-13-05) have been purchased from Dharmacon Inc (Lafayette, CO, USA).The Institutional Evaluation Board of Laval University (Quebec, QC, Canada) authorized the study, and volunteers signed a consent type. Neutrophils have been collected from healthful adult volunteers and isolated as previously described [15]. They were resuspended in Mg 2+ -free Hanks’ balanced salt solution (HBSS) containing 1.6 mM CaCl2. The myeloid cell line PLB-985 was obtained from the German Collection of Microorganisms and Cell Cultures (DSMZ; Braunschweig, Germany) and grown in RPMI 1640 medium containing ten decomplemented fetal bovine serum (FBS), ten mM HEPES, 1 mM Na+ pyruvate at 37 within a five CO2 humidified atmosphere. The cells have been maintained in culture for 12 passages ahead of new batches have been thawed. To induce differentiation to a neutrophil-like phenotype, PLB-985 cells have been cultured in medium supplemented with 0.3 mM dibutyryl cAMP for 3 days before every experiment.Transfection of dibutyryl cAMP-differentiated PLB-985 cellsOne day following the initiation of differentiation with 0.three mM dibutyryl cAMP, PLB-985 cells were transiently transfected using a nucleofection program obtained from Amaxa Biosystems (Cologne, Germany). Briefly, 2 106 cells were centrifuged and resuspended in one hundred of nucleofection buffer (25 mM HEPES, pH 7.4, 120 mM KCl, two mM MgCl2, 10 mM K2HPO4, five mM L-cysteine) containing three of MICL-specific siRNA (siMICL) or damaging manage siRNA (siCtrl). The samples were transferred into an electroporation cuvette, and transfections were perfor.
