Transient expression of two selected viral proteins fused to GFP, N, and NSs following agroinfiltration was validated by western blot. Soluble proteins from agroinfiltrated leaf tissues at 2 dpi (for localization assay) or 3 dpi (suppression of RNA silencing assay) were extracted in protein sample buffer (Laemmli, 1970 (link)) and separated on a SDS-12% polyacrylamide gel. Proteins were transferred to PVDF membrane (Millipore) and detected using mouse anti-GFP antibodies (1:1000, Roche Life Science) or mouse monoclonal anti-Flag M2 clone 2 antibody (1:2000, Sigma–Aldrich) followed by rabbit anti-mouse IgG horseradish peroxidase conjugate (1:25,000), Pierce ECL Plus chemiluminescent substrate, and exposure to x-ray film (Fujifilm). Protein sizes were estimated using pre-stained Page Ruler protein ladder (Thermo Fisher Scientific).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Neurospheres were fixed with phosphate-buffered saline (PBS) containing 4% paraformaldehyde for 40 min in normal incubation conditions (i.e., at 30°C and 5% CO 2 ).
They were then immunolabeled as described previously (Dong et al. 2017 , Aulestia et al. 2018) . The correct localization of apoaequorin-GFP to the mitochondria was confirmed by the co-localisation of GFP and TOM20 signals. TOM20 is a 20 kDa translocase of the mitochondrial outer membrane (Eliyahu et al. 2010) . TOM20 was detected using the rabbit anti-TOM20 antibody (Santa Cruz Biotechnology, at a 1:100 dilution). To enhance the EGFP signal, samples were also labeled with a mouse anti-GFP antibody (Roche; at a 1:1,000 dilution). The secondary antibodies (Alexa Fluor-488 goat anti-mouse IgG and Alexa Fluor-555 goat anti rabbit IgG; Molecular Probes, Invitrogen, Eugene, OR, USA) were both used at 1:1,000 dilution. Images of immunolabeled cells were acquired with a Leica TCS SP5 II laser scanning confocal microscope mounted on a Leica DMI 6000 microscope using a Leica HCX PL APO 40/1.25 N.A. oil immersion lens. EGFP fluorescence was captured using 488 nm excitation and 510-550 nm detection; TOM20 fluorescence was captured with 561 nm excitation and 570-620 nm detection; and DAPI fluorescence was captured using 405 nm excitation and 430-480 nm detection.

HEK 293T cells in 35 mm diameter wells were transfected using Lipofectamine 2000 (Thermo Fisher Scientific). Twenty four hours posttransfection, cells were rinsed with PBS and resuspended in 400 μl NP buffer (50 mM Tris–Cl pH 7.5, 150 mM NaCl, and 1% Nonidet P40) with protease inhibitor mix (Roche Diagnostic), PMSF (0.1 mg/ml), and RNase A (10 ng/μl). After vortexing for 30 s, cell extracts were clarified by centrifugation at 20,000g for 10 min at 4 °C. The soluble extract was then incubated with 1.2 μg of a mouse anti-GFP antibody (Roche Diagnostic, Cat. Nr. 11814460001) for 1 h at 4 °C and next with 30 μl of protein G Sepharose beads (Cytiva). Beads were washed four times with washing buffer (50 mM Tris–Cl pH 7.5, 150 mM NaCl, and 0.1% Nonidet P40) before resuspension in Laemmli buffer for SDS PAGE analysis. UHMK1 was revealed with the rat monoclonal antibody 3B12 (11 ) (hybridoma supernatant at 1:20 dilution). GFP-fusion proteins were detected with a rabbit anti-GFP antibody (Santa Cruz SC8334, 1:1000). Primary antibodies were then detected with IRDye680 or IRDye800 secondary antibodies (Li-Cor). Western blots were imaged with Typhoon infrared laser (Amersham, GE Healthcare). Alternatively, gels were imaged using Pro-Q Diamond (Thermo Fisher Scientific) and imaged on the laser scanner at 532 nm. Gels were then restained with Coomassie Blue before scanning at 680 nm.

Fractions (16 s) were collected from a polysome profiling experiment of either exponential or PBS stressed DHH1-YFP tagged cell lysate (60 OD260 cell extract per gradient). Ten microlitres of every third fraction was mixed with 2x Laemmli buffer, denatured at 95 °C for 2 min, loaded on a 10% SDS-PAGE gel, and run for 1 h at 160 V. The gel was transferred onto a nitrocellulose membrane (Amersham Biosciences) and blocked for 1 h in 1x PBS containing 0.1% Tween-20 in 5% nonfat dry milk. The membranes were incubated with mouse anti–GFP antibody (1:1000, Roche; cat. number: 11814460001) at 4 °C overnight. After washing (3 × 10 min each with 1 x PBS, 0.1 % Tween-20) horseradish peroxidase conjugated secondary antibodies were added for 1 h at room temperature (1:3000; Roche). The membranes were washed as before and results were visualized using an enhanced chemiluminescence SuperSignal West Femto Maximum Sensitivity Substrate (ThermoFisher Scientific).

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.
