013 British Society for Immunology, Clinical and Experimental Immunology, 175: 485?CLEC16A protein functionvector (Origene) to obtain constructs with tGFP (turbo GFP, an enhanced variant of GFP) fused for the N- or C-terminal, respectively. The AsiSI and MluI restriction sites have been utilised. The resulting constructs were confirmed by sequencing. 5 g of either N-terminal or C-terminal CLEC16A-tGFP were transfected into K562 cells as described below. The pCMV-AC-tGFP vector that expresses tGFP only was employed as a handle. Fusion protein expression was verified by fluorescence microscopy and Western blot, as described beneath, applying a (t)GFP-specific monoclonal primary antibody, anti-tGFP (2H8) (1:2000; cat. no. TA150041) (Origene), followed by a horseradish peroxide (HRP)-conjugated goat anti-mouse secondary antibody (1:2000; cat. no. NED822061EA) (Perkin-Elmer, Waltham, MA, USA).CLEC16A mRNA expression levels were quantified and normalized relative to the human GAPDH (glyceraldehyde 3-phosphate dehydrogenase) housekeeping gene expression by qPCR, applying the TaqMan method (Applied Biosystems, Foster City, CA, USA), the MX-3000P real-time PCR program and the MX-Pro application (Stratagene, La Jolla, CA, USA). Primer and probe sets had been selected from Applied Biosystems’ assays on demand solution list as follows: CLEC16A (Hs01074744_m1) and GAPDH (Hs99999905 _m1). Every target was run in triplicate with 2?of FastStart universal probe master mix (Roche, Indianapolis, IN, USA) along with the primer/probe set inside a 20-l total reaction volume, as per the manufacturer’s protocol.2H-Pyrano[3,2-c]pyridin-4(3H)-one custom synthesis Transfection of LCLs and K562 cellsLCLs. Cells were treated with either 1? g of CLEC16Atargeting siRNA (KD), scrambled duplex (SD) or fluorescent duplexes. We resuspended 3 ?105 LCLs/condition in 75 l of complete medium, mixed with 1? g of siRNA duplex inside a 1-mm cuvette (Bio-Rad, Hercules, CA, USA) and electroporated utilizing a GenePulser II (Bio-Rad) set to provide a distinctive square wave pulse of 500 V for 0? ms at room temperature. Cells have been incubated inside the cuvette at 37 for 10 min after which transferred into 12-well plates containing 1? ml of prewarmed comprehensive RPMI medium. Transfection efficiency was assessed by flow cytometry utilizing the Fl-2 channel of a FACS Calibur flow cytometer and analysed with CellQuest computer software (BD Biosciences, San Jose, CA, USA).Price of 5-Bromobenzene-1,3-diol Cell viability was measured by Trypan blue exclusion (Life Technologies, Carlsbad, CA, USA) following the manufacturer’s protocol.PMID:23399686 Knock-down efficacy at the RNA and protein level in LCLs was evaluated by quantitative polymerase chain reaction (qPCR) and Western blot, respectively, as described under. K562 cells. Cells have been combined with 5 g of either N-terminal or C-terminal CLEC16A-GFP. We resuspended 1 ?106 K562 cells/condition in 100 l of cell line Amaxa Nucleofector solution V (Lonza, Basel, Switzerland) and transfected following the manufacturer’s instructions, using program T-016 around the Amaxa Nucleofector II device (Lonza). Following transfection, cells had been then transferred into 12-well plates containing 1? ml of prewarmed full RPMI medium.Protein extraction and quantification and Western blotTotal protein was extracted from LCLs 24?two h soon after siRNA transfection and in K562 cells, 24 h soon after transfection using the CLEC16A-GFP construct. Briefly, cells have been lysed in Talon xTractor buffer (Clontech, Mountain View, CA, USA) containing 1 0? M phenylmethanesulphonyl fluoride (PMSF) (Sigma-Aldrich, St Louis, MO, USA) and 1 protease inh.
