Protein Extraction and Detection from Plant Tissues

Crude extracts were obtained from N. benthamiana, P. persica, and A. thaliana by homogenization of ground frozen leaf tissues in disruption buffer (50 mM Tris-HCl, pH 7.5, 6 M urea, 2% SDS, and 5% β-mercaptoethanol). After centrifugation at 13,000 × g for 10 min, samples were boiled for 5 min at 95°C. Proteins were separated in SDS-PAGE gels (12% acrylamide) and electroblotted onto a nitrocellulose membrane. The CP from PPV was detected with a specific rabbit serum used as the primary antibody and horseradish peroxidase (HRP)-conjugated goat anti-rabbit IgG (Jackson ImmunoResearch) as the secondary reagent. MYC-tagged proteins were detected with a specific anti-MYC monoclonal antibody (AbMART) and HRP-conjugated sheep anti-mouse IgG (Sigma) as the secondary antibody. Immunostained proteins were visualized by enhanced chemiluminescence detection with Clarity ECL Western blotting substrate (Bio-Rad) in a ChemiDoc system (Bio-Rad). Band intensity in arbitrary units was estimated by using Image Lab software (v.6.0.0), with the signal of one selected sample considered as the reference. Ponceau red staining of membranes was used to check the global protein content of samples.

SCLC cell lines cultured in 12-well flat-bottom plates in 3ml culture medium were collected (1×106 for NCI- H82, NCI-H146, and NCI-446; 1.5×105 for NCI-H196) and lysed during 0.5h on ice in 150μl lysis buffer (62.5mM Tris-HCl [pH 6.8], 2% lauryl sulfate sodium, 10% glycerol 50mM DTT). Equal amounts of lysates were separated by 12% SDS-PAGE, electrotransferred onto a nitrocellulose membrane, and immunoprobed with antibodies against phospho-FAK (Tyr397) (1/1000, rabbit monoclonal; Cell Signaling Technology, Danvers, MA), total FAK (1/200, rabbit polyclonal; Santa Cruz Biotechnology); PARPp85 (1/1000, rabbit polyclonal; Promega, Madison, WI), phospho-Paxillin (Tyr-118) (1/1000, rabbit polyclonal; Cell Signaling Technology), total Paxillin (1/1000, monoclonal mouse; BD Biosciences, San Diego, CA), and β-Actin (1/1000, mouse monoclonal; Sigma). Secondary antibodies consisted of HRP-conjugated goat anti-rabbit IgG (1:2000; Cell signaling Technology) or HRP-conjugated sheep anti-mouse IgG (1:10000; Sigma). Immunoreactive bands were developed using chemiluminescence (Amersham ECL; GE Healthcare, Little Chalfont, Buckinghamshire, UK),detected with a Chemidoc XRS apparatus (Bio-Rad, Hercules, CA), and densitometrically quantified using Quantity One software (Bio-Rad) (results shown in Supplementary Fig.S1).

Western Blot Analysis of CD3ζ Protein

Cells were lysed in 1% CHAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulphonate) buffer [phosphate-buffered saline (PBS), 1% CHAPS, 0·5% sodium deoxycholate, 2% sodium dodecyl sulphate] containing complete protease inhibitor cocktail tablets (Roche, Indianapolis, IN, USA) for 30 min, then centrifuged through polymer wool to clear the supernatant. Protein concentrations were established using a protein estimation kit (Bio-Rad, Hercules, CA, USA). Reduced or non-reduced samples containing 20 μg of total protein were separated on 10% sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) gels, transferred to Hybond nitrocellulose membranes (Amersham Biosciences, Pittsburgh, PA, USA) and probed with mouse anti-human CD3ζ (BD Biosciences) followed by HRP-conjugated sheep anti-mouse IgG (Sigma-Aldrich), both diluted 1:1000 in PBS-Tween/5% skimmed milk powder. Bands were resolved using an ECL Western Blotting Detection kit (Amersham Biosciences), according to the manufacturer's instructions, and the membranes were analysed by exposure to X-ray film.

AdC7αRSV or AdC7GFP (5 × 1010 pu each) diluted in 40 μl PBS were administered intranasally or intramuscularly to 8-week-old female BALB/c mice. Neonatal mice received either 3 × 1010 pu (5μL) or 6 × 1010 pu (10 μL) of the vectors intranasally. The levels and kinetics of anti-RSV IgG following administration of AdC7αRSV were quantified in serum and bronchoalveolar lavage (BAL) by ELISA. Serial dilutions of serum and BAL were added to flat-bottomed 96-well EIA/RIA plates (Corning, Corning, NY, USA) coated with 1μg/mL of human anti-palivizumab clone AbD23967 (HCA261, Bio-Rad-Antibodies, Hercules, CA, USA), followed by PBST + 5% blotting grade blocker (Bio-Rad Laboratories, Hercules, CA, USA. Detection was performed using an HRP-conjugated sheep anti-mouse IgG (Sigma, St. Louis, MO, USA) in PBS + 1% blotting grade blocker and substrate (hydrogen peroxide/tetramethylbenzidine) (R&D systems, Minneapolis, MN, USA) and the absorbance at 450 nm was measured. Titers were calculated with a log (OD)–log(dilution) interpolation model, with detection cut-off equal to 2-fold the background absorbance. Half-life (t1/2) was calculated by the formula: where t = time elapsed, N0 = titer at 1 week, and Nt = titer at 4 weeks after the administration of AdC7αRSV.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
