Western blot was performed on triplicate infections carried out in confluent HFF in 6-well plates at the indicated MOI and treatment conditions. Sonicated whole-cell extracts in lysis buffer containing phosphatase and protease inhibitors were prepared as previously described (44 (link)). The gel-loading buffer contained 2% SDS and 100 mM beta-mercaptoethanol. The proteins were fractionated on freshly made 8% SDS-PAGE Tris-glycine gels prior to transfer to Amersham Protran 0.45-μm nitrocellulose membranes (GE Healthcare Life Sciences 10600002). HCMV IE1-72 and IE2-86 were detected by murine monoclonal antibody MAB810 (EMD Millipore, 1:1,000 dilution). Host actin was detected with polyclonal rabbit anti-actin antibody (Sigma-Aldrich, A2066, 1:4,000 dilution). Primary antibodies were detected with peroxidase AffiniPure F(ab’)2 fragment goat anti mouse IgG (Jackson ImmunoResearch, 115-036-006) at 1:40,000 dilution and goat anti-rabbit IgG (whole molecule)–peroxidase antibody (Sigma-Aldrich, A0545) at 1:40,000 dilution. Blots were imaged and analyzed using the iBright FL1500 Imaging System (Invitrogen).

To test the quality and specificity of the sera produced against the PHB recombinant proteins, we loaded 20 μg of protein from different purification samples and mixed with 2× Laemmli sample buffer [15 ]. Samples were loaded on 12.5% PGE-SDS gels and afterwards the electrophoresis gels were stained with Coomassie blue or silver nitrate [16 (link)]. Protein bands were transferred onto a PVDF membrane (Mini ProBlott Membranes, Applied Biosystems, Foster City, CA, USA) using a Bio-Rad transblot. Membrane strips were then incubated for 2 h at 37 °C with diluted 1:50 sera and, after several washes with PBST (PBS + Tween20), they were incubated for 2 h at RT with rabbit anti-mouse IgG (whole molecule)-peroxidase antibody (Sigma Aldrich, St. Louis, Missouri, USA) for Leish r PHB1 or with goat anti-rabbit IgG (whole molecule)-peroxidase antibody (Sigma Aldrich) at 1:1,000 for Leish r PHB2. Samples were developed using diaminobenzidine tetrahydrochloride (Sigma Aldrich) as a substrate (0.05% w/v) and H2O2 (dilution 1/5000).

Protein samples were separated on home-made polyacrylamide gels and transferred to a PVDF film (Immobilon-P; Millipore) using a semi-dry method. After being blocked for 1 h at room temperature with blocking solution containing 5% milk in PBST (2.56 g/L Na2HPO4·7H2O, 8 g/L NaCl, 0.2 g/L KCl, 0.2 g/L KH2PO4, 0.1% Tween-20, pH 7.4), the film was incubated with primary antibody in PBST containing 3% bovine serum albumin (BSA; Sigma) overnight at 4 °C and then washed 3 times with PBST followed by incubation with 1:10000 dilution of Goat Anti-Mouse IgG (whole molecule)-Peroxidase antibody (Sigma) or Goat Anti-Rabbit IgG (whole molecule)-Peroxidase antibody (Sigma) in blocking solution for 1h at room temperature. After being washed 3 times with PBST, the PVDF film was developed with ECL prime (GE Healthcare) and visualized on X-ray film (GE Healthcare). The primary antibodies were anti-GFP (1:1000; Abmart), anti-Myc (1:1000; Sigma), anti-flag (1:2500; Sigma), anti-His (1:500; Sigma), anti-GST (1:1000; Cell Signaling Technology), anti-Ub (1:1000; Cell Signaling Technology) anti-CUL1 (1:1000) [42 (link)], anti-PIF3 (1:500) [10 (link)], anti-RPN6 (1:1000) [43 (link)] and anti-RPT5 (1:1000) [43 (link)].

MCF-7 and TamR MCF-7 cells, which were cultured in a 6-well plate until their confluency levels reached 40–50%, were treated for 24 h with 4-OHT at the indicated concentrations. The cells were lysed with CelLytic M cell lysis reagent (Sigma-Aldrich), and the supernatant was collected for Western blot analysis. Primary antibodies employed for Western blot analysis included those recognizing human ATF3 (Santa Cruz Biotechnology, sc-81189), YTHDF2 (EMD Millipore, Q2490423), ABCB1 (ABclonal, A11747), and AK4 (Santa Cruz Biotechnology, sc-271161). Goat anti-rabbit IgG (whole molecule)-peroxidase antibody (Sigma-Aldrich, A0545) and m-IgGκ BP-HRP (Santa Cruz Biotechnology, sc-516102) were used as secondary antibodies. Membranes were also probed with anti-GAPDH antibody (Santa Cruz Biotechnology, sc-32233) to confirm equal protein loading.

Approximately 2 × 107 cells were harvested and lysed in CelLytic M Cell Lysis reagent supplemented with a complete protease inhibitor cocktail (Sigma-Aldrich). The lysates were subjected to rotation at 4 °C for 15 min, followed by sonication using a Qsonica sonicator q125 (1/8 probe) for 15 s three times (42% amplitude, 15 s on/15 s off). After sonication, the cell lysates were rotated for another 15 min and then centrifuged at 13,000 rpm for 10 min at 4 °C. The supernatant was incubated with prewashed anti-Flag M2 beads at 4 °C for 2 h. The beads were washed three times with PBS-T (PBS buffer containing 0.05% Tween 20), and subsequently boiled in 2× SDS–PAGE loading buffer to elute the captured proteins for western blot analysis.
Antibodies recognizing human XPO5 (Proteintech, #28628–1-AP; 1:2000), SOD1 (Proteintech, #10269–1-AP; 1:4000), V5 (Proteintech, #14440–1-AP; 1:2000), streptavidin (Thermo Scientific, #S911), and lamin B1 (Proteintech, #12987–1-AP; 1:10000) were used as primary antibodies for western blot analysis. Goat antirabbit IgG (whole molecule)-peroxidase antibody (Sigma, #A0545; 1:4000) and m-IgGκ BP-HRP (Santa Cruz Biotechnology, #sc-516102; 1:4000) were employed as secondary antibodies. Anti-GAPDH (Santa Cruz Biotechnology, #sc-32233; 1:10000) was used for internal control (GAPDH) to confirm an equal amount of protein loading.

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.
