For immunoprecipitation assays, cells were lysed in Lysis Buffer (50 mM Tris pH8, 150 mM NaCl, 1% NP-40, and 1 mM EGTA) supplemented with 0.1M NaF, phosphatase inhibitor cocktails 2 and 3 (Sigma) and protease inhibitor cocktail (Roche). Cell extracts were cleared at 16,000 g for 20 min at 4°C. FLAG-tagged proteins were purified using anti-FLAG M2 Affinity Agarose Gel (Sigma), whereas immunoprecipitation of Myc-tagged proteins was carried out using Protein A Sepharose (Sigma). Detection of purified proteins and associated complexes was performed by immunoblot analysis using chemiluminescence (Pierce). Western Blots were probed with mouse anti-FLAG (M2, Sigma), rabbit anti-FLAG (Sigma), mouse anti-Myc (9E10, Santa Cruz Biotechnology), rabbit anti-Myc (Santa Cruz Biotechnology), rat anti-HA (3F10, Roche Applied Science), mouse anti-Tubulin (E7, Developmental Studies Hybridoma Bank, DSHB) and mouse anti-GFP (in-house produced), rat anti-Yki [47 (link)], and rabbit [48 (link)] and guinea pig anti Sav (a kind gift from G. Halder).

Cells were harvested with RIPA buffer (Cold Springs Harbor protocols) containing protease and phosphatase inhibitors, and proteins were separated on a 4%–12% Bis-Tris gradient gels (Thermo-Fisher). and transferred to Pure Nitrocellulose Blotting Membrane (Life Sciences) or Amersham™ Hybond™ PVDF membrane (0.45 μM GE Healthcare Life Science). Membranes were blocked with 4% BSA, incubated with primary antibody overnight (1:1000–1:2000 dilution), washed, and incubated with secondary fluorescent conjugate anti-bodies or HRP, followed by a last wash. Membranes were scanned using LI-COR Odyssey CLX, Bio-rad Chemidoc™ or exposed to film.
Primary antibodies used are: Mouse monoclonal anti-p53 (Santa Cruz Biotechnology Cat# sc-126, RRID:AB_628082), mouse monoclonal anti-MDM2 (Ab-1, Millipore Cat# OP46T-10UG, RRID:AB_564805), rabbit anti-pChk2 (T68) (Cell Signaling Technology), rabbit anti-pChk1 (S317) (Cell Signaling Technology), mouse anti-tubulin (E7) (Developmental Studies Hybridoma Bank), mouse monoclonal anti-β-Actin (AC-74) (Sigma-Aldrich Cat# A2228, RRID:AB_476697).

S2 and HEK293T cells were lysed with HEPES lysis buffer (150 mM NaCl, 50 mM HEPES pH 7.5, 0.5% (v/v) Triton X-100 supplemented with protease inhibitor cocktail with EDTA (Roche) and the soluble fraction was obtained by centrifugation (16,000 × g, 20 min). For co-IP experiments cleared lysates were added to 20 μL of ANTI-FLAG M2 Affinity Gel (Sigma-Aldrich) or 15 μL of GFP-Trap agarose (ChromoTek) in 100 μL HEPES lysis buffer. The lysate and the beads were incubated for 1 h at 4 °C and washed four times with HEPES lysis buffer. Input and co-IP samples were analysed by SDS-PAGE and western blot. Primary antibodies were: mouse anti-FLAG (M2), 1/5000 (Sigma-Aldrich F1804); mouse anti-GFP (3E1), 1/1000 (Cancer Research UK); rat anti-HA (3F10), 1/2000 (Roche); mouse anti-Myc (9E10), 1/5000 (Santa Cruz sc:40); mouse anti-Tubulin (E7), 1/5000 (Developmental Studies Hybridoma Bank); mouse anti-V5 (R960-25), 1/5000 (Thermo Fisher), rabbit anti-P-TAZSer89 1/1000 (E1X9C) (Cell Signalling Technologies 59971), rabbit anti-HA 1/1000 (C29F4) (Cell Signalling Technologies 3724). Secondary antibodies were from GE Healthcare (1:5000).

Ten µg of protein from cell lysates were run on PAGE gels as we have done before[14 (link)] and transferred to a nitrocellulose membrane. The membrane was treated with blocking buffer for 1 h at room temperature, followed by incubation in 1:1000 dilution rabbit anti-cleaved Caspase-3 (Cell Signaling #9664), 1:2000 dilution rabbit anti-ISG54 (Thermo-Fisher #PA3-845), 1:1000 dilution of rabbit anti- p27Kip (Cell Signaling 3688). or 1:500 mouse anti-tubulin E7 (Developmental Studies Hybridoma Bank, University of Iowa, Department of Biological Sciences, Iowa City, IA) and then goat anti-mouse-IgG-Alexa Fluor680- (1/5000) or donkey anti-rabbit-IgG-IRDye® 800CW. The membrane was washed three times and then scanned with a LICOR Odyssey® Infrared Imaging System.

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.
