The membrane was blocked for 1 hour in buffer containing PBS-T (0.1% Tween-20) + 5% milk then incubated 16 h with the appropriate antibody (1∶1000) in the same buffer.
The membrane was blocked with 5% nonfat dry milk overnight and then incubated with either procaspase-9 alone or procaspase-9 in the presence of ATP and 1% BSA for 1 hour in Buffer A (20 mM HEPES-KOH, pH 7.5, 10 mM KCl, 1.5 mM MgCl2, and 1 mM each of EDTA, EGTA, and DTT) at room temperature.
One microgram of GST-mIF4E was incubated for 1 hour with 25 µl of m7GTP-Sepharose beads in buffer A. After washing, the beads were incubated for 1 hour in buffer A, containing 1 mg/ml of BSA, 0.5% Igepal with one, two or ten micrograms of GST-Sg4E-BP, GST-Sg4E-BP 4xE or GST-SgIF4G.
One microgram of GST-mIF4E was incubated for 1 hour with 25 µl of m7GTP-Sepharose beads in buffer A. After washing, the beads were incubated for 1 hour in buffer A containing 1 mg/ml of BSA, 0.5% Igepal with one microgram of GST, GST-Sg4E-BP, GST-Sg4E-BP YALA, GST-4E-BP 4xA, GST-Sg4E-BP 4xE, GST-Hu4E-BP, GST-Hu4E-BP YALA or GST-Hu4E-BP 4xE.
After deparaffinisation in Xylene, the tissue microarrays were autoclaved for at least one hour in buffer S1699 or S2367 (Dako Norden A/S, Denmark) or Borgs Decloaker pH9 buffer solution (Biocare Medical, CA, USA) (Table 2).
Proteins were separated by SDS-PAGE (Bio-Rad Laboratories), tranitrocellulosetrocellulose membranes (Thermo Scientific), blocked for 1 hour in buffer containing 5%% nonfat dry milk (Lab Scientific) or 5%% bovine serum albumin, and incubated with the appropriate primary antibody overnight.
Cryosections were re-hydrated in PBS, permeabilized with 0.3% Triton X-100 in PBS for 15 min, and incubated for 1 hour in blocking buffer (goat serum dilution buffer).
After the external and gut homogenates were prepared and incubated 24 hours in buffered peptone water (BPW), each one of the growth from BPW was inoculated in seven primary media (Mac-Conkey, Sheep Blood Agar, Chocolate agar, SS agar, Desoxycholate Citrate Agar-DCA, Xylose Lysine Deoxycholate- XLD and Mannitol Salt Agar-MSA) to grow most gram positive and negative bacteria [ 6, 14].
Membranes were washed 3x in TBST before adding secondary antibodies conjugated to peroxidase for 1 hour in milk buffer.
Blots were pre-hybridized for 1 hour in hybridization buffer at 45°C and then hybridized with probes overnight at 45°C.
Non-specific labelling was blocked by incubation for one hour in blocking buffer (1% (w/v) bovine serum albumin in PBS) at room temperature.
