After 1 h blocking in 5% non-fat milk solution (Bio-Rad 170–6404) at room temperature, membranes were incubated with anti-CD63 (1:1000 dilution), anti-Bip (1:1000 dilution) (BD Biosciences 556019 and 610978, respectively), anti-CD81 (1:1000 dilution), anti-Rab27 (1:1000 dilution) (Santa Cruz Biotechnology sc23962, sc74586), anti-TSG101 (1:500 dilution), anti-CD9 (1:500 dilution), anti-Syntenin (1:500 dilution), anti-Calnexin (1:2000 dilution), or anti-GM130 (1:1000 dilution) (the last five antibodies were Abcam ab125011, ab92726, ab133267, ab22595, and ab76154) overnight at 4°C. The membrane was washed 3 times for 8 min in PBST while shaking, then incubated with HRP-conjugated secondary antibody (1:10000 dilution) (Santa Cruz Biotechnology sc-2357, sc-516102) at room temperature for 1 h.

Total protein concentration in the plasma samples was determined using Pierce BCA Protein Assay (Thermo Fisher, Waltham, MA). General protein separation was carried out by electrophoresis on 4–20% gradient SDS-PAGE gels at 110 V for 1.25 h and transferred to nitrocellulose membranes (Bio-Rad Laboratories, Inc., Hercules, CA). Transfer membranes were then incubated in blocking buffer (1% BSA in TBST) at 4 °C under gentle agitation overnight. Blocked membranes were probed with primary recombinant monoclonal antibodies for trypsin (ab200997, 1:1000, Abcam, Cambridge, MA), pancreatic lipase (ab124915,1:30000, Abcam), and Transferrin (ab82411, 1:10,000, Abcam) before incubated in the corresponding secondary antibody (ab205718, 1/5000, Abcam). Membranes were incubated with Pico Chemiluminescent Substrate (Thermo Fisher Scientific) and then imaged via photo-sensitive autoradiography film (Genesee Scientific, San Diego, CA). Western blot images were digitally analyzed (gel analysis tool, Image J; NIH). The band density values for each of the western blots for trypsin and lipase were normalized to their respective transferrin values.

Quantification of Endogenous Proteins by Western Blot

Check if the same lab product or an alternative is used in the 5 most similar protocols
Western blot samples were lysed with lysis buffer [20 mM tris-HCl (pH 7.5), 150 mM NaCl, 1 mM phenylmethylsulfonyl fluoride (Sigma-Aldrich), protease inhibitor cocktail, 1% Triton X-100 (Serva), and 10% glycerol]. Lysates were analyzed with SDS–polyacrylamide gel electrophoresis gels (Invitrogen). The different time points were loaded in a random manner to avoid quantification bias (figs. S7 and S8). Proteins were transferred onto a polyvinylidene difluoride (PVDF) membrane (Millipore) by wet blotting. Detection was performed with the Pico Chemiluminescent Substrate from Thermo Scientific and a charge-coupled device camera (Intas).
In probe-expressing CD95-HeLa and wild-type HeLa cell lines that were used for time series experiments, we quantified endogenous FADD, p55, and BID concentrations using calibrated GFP fusion proteins (figs. S9 to S11). First, GFP fusion protein lysates were calibrated to recombinant eGFP (BioVision). We combined equal amounts of lysates of nontransfected cells with lysates of the fusion protein–expressing cells. This mixed lysate was combined with different amounts (0.1 and 30 ng) of GFP and then loaded onto Western blot gels. Different amounts of these calibrated fusion protein lysates were loaded onto Western blot gels along with lysates from the cleavage probe–expressing cell lines that were used for time series experiments.

Cells were lysed in RIPA buffer (20mM Tris-HCl, 0.1% SDS, 1% Triton X-100, 1% sodium deoxycholate) containing protease inhibitor (Roche). The resulting lysates were run on 10% Mini-PROTEAN® TGX™ Gel (Bio-Rad) and transferred to Amersham Hybond-P membrane (GE Healthcare). The following antibodies were used (all are from Cell Signaling Technology): rabbit anti-connexin 43 (1:500, Cat. no. 3512, RRID: AB_2294590), rabbit anti-pSMAD1/5/9 (1:1000, Cat. no. 13820, RRID: AB_2493181), and rabbit anti-GAPDH (1:2000, Cat. no. 2118, RRID: AB_1031003). SuperSignal West Femto Chemiluminescent substrate was used to detect anti-connexin 43 and anti-pSMAD1/5/9, and Pico Chemiluminescent substrate (Thermo Scientific) was used to detect anti-GAPDH.

Whole-cell lysates were obtained by resuspending cell pellets in RIPA buffer (50 mM Tris pH 7.4, 150 mM NaCl, 1% Triton X-100) with freshly added protease inhibitor (Roche).

The membrane was blocked with 5% milk at room temperature for 1 h then probed with primary antibodies overnight at 4°C. The membrane was washed with TBST and then incubated with corresponding secondary antibody for 1 h at room temperature. The targeted proteins were visualized with super signal West Pico Chemiluminescent Substrate (Thermo Scientific, USA). The anti-β-actin antibody (Sigma, Cat #A2228) was used as an internal control. Densitometry was performed using Image J (National Institutes of Health, USA). Protein levels were normalized to β-actin.

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.
