We used WB to detect ApoE positive fractions collected from the heparin binding columns. Fractions were diluted in 10 μL RIPA buffer (Cell Signaling Technology), 4 μL DTT (1 M, Sigma Aldrich) and 10 μl Laemmli buffer (Boston Bioproducts) to a final volume of 40 μl and denatured 5 min. at 60°C. Samples were separated electrophoretically for 1h at 70 V using 4–20% pre-cast gradient gels (Mini-PROTEAN® TGX™, Bio-Rad) and SDS-Tris-Glycine buffer. Proteins were transferred to nitrocellulose membranes (VWR; 27376–991) for 1 hour at 70 V. Membranes were blocked 1 hour with Odyssey Blocking Buffer (LI-COR Biosciences, Lincoln, NE), and probed either 1 h room temperature (R.T.) or over-night at 4°C with anti-his tag antibody (rb, 1:5000, Novus biologicals), and 1 hour R.T. with IRDye 800CW donkey anti-rabbit (1:10000, LI-COR Biosciences) antibodies. Immunoreactive bands were visualized using the Odyssey Infrared Imaging System and visualized on the Image Studio version 2.1 (LI-COR Biosciences). A composite of individual gels was used to generate Figure 2. All western blotting reported in Figure 2 are representative of two independent experiments.

Unless otherwise stated, cells for western blot analysis were treated for 72 hours before being lysed. Cells were lysed using RIPA buffer (Cell Signaling Technology, Danvers, MA, USA) and protein concentration measured using the bicinchoninic acid (BCA) assay kit (Thermo Fisher Scientific, Inc Waltham, MA, USA). A total of 10‐20 μg of protein was separated by 4‐20% Mini‐PROTEAN TGX precast gels (Bio‐Rad, Hercules, CA, USA) and transferred to Immobilon™‐FL PVDF transfer membranes (Thermo Fisher Scientific, Inc). Membranes were dried overnight, wetted with methanol, and blocked with Odyssey Blocking Buffer (LI‐COR Biosciences, Lincoln, NE, USA) for 1 hour prior to incubation with primary antibodies, mouse anti‐RUNX1 (sc‐365644), mouse anti‐p‐RUNX1 (sc‐293146), mouse anti‐JNK (sc‐7345) mouse anti‐p‐JNK (sc‐6254) (Santa Cruz Biotechnology) and rabbit anti‐β‐actin antibody (4970S, Cell Signaling Technology) for 4 hours at room temperature (RT). Membranes were subsequently washed with TBST and incubated with secondary antibodies (IRDye 680RD donkey anti‐rabbit and IRDye 800CW donkey anti‐mouse (dilution 1:4000) (LI‐COR Biosciences). After rinsing twice with TBST, immunoreactive bands were visualized using the Odyssey Infrared Imaging System, and band intensities normalized to β‐actin were quantified using Image Studio version 2.1 (LI‐COR Biosciences).

Astrocyte and Neuron Protein Extraction

Protein was extracted from primary murine astrocyte and neuron co-cultures using MPER while TPER was used to extract protein from human hippocampal tissue (Thermo Scientific, CA, USA). Bradford protein assay determined protein concentrations of MPER- or TPER- soluble fractions. Protein extracts were subsequently immunoblotted with the following antibodies: GLT-1 (a kind gift from Dr. Jeffrey David Rothstein, Johns Hopkins University), IL1-β (Biovision, CA, USA), tubulin and GAPDH (Abcam, MA, USA) were used to control for protein loading or to confirm no cross-contamination of each fraction. Band intensity was measured using the Odyssey Image station and Image Studio (version 2.1, Li-Cor Biosciences, NE, USA) and normalized by corresponding loading control protein.

Mouse lungs were fixed in zinc-buffered formalin, processed, embedded in paraffin, cut into 5-μm sections, and mounted on glass slides. Citrate-mediated antigen retrieval was performed, and then the following antibodies were used for detection: anti-β-catenin (Cell Signaling Technology), anti-AQP5 (Calbiochem), anti-Ki67, (Abcam), anti-BrdU, anti-CC10, anti-Cyclin D1, anti-SPC, anti-NKX2.1 (also known as TTF-1) (Santa Cruz Biotechnology), and c-MYC (Epitomics).

Fifty-microgram aliquots of cell proteins were probed with antisera against c-MYC (Epitomics), Cyclin D1, p-ERK1/2 (pT202/PY204), total ERK1/2 (Cell Signaling Technology), and anti-β-actin (Sigma).

Immunopreciptated 3XFLAG-syntaxin 6 and 3XFLAG-syntaxin 6 ΔYGRL were incubated with Sphingostrips (S-6000) or PIPstrips (P-6001) (Echelon Biosciences Inc., Salt Lake City, UT). Briefly, 3XFLAG-syntaxin 6 and 3XFLAG-syntaxin 6 ΔYGRL were immunopreciptated from HeLa cells as described above. Protein eluates were quantitated and 8.4 or 2.5 μg of protein was incubated for 24 h in Tris buffered saline (TBS) (50 mM Tris, pH 7.4, and 150 mM NaCl) with Sphingostrips or PIPstrips, respectively. Unbound proteins were removed by washing three times with TBS-0.1%Tween-20. The strips were then processed by blotting with mouse anti-FLAG M2 primary antibody and goat anti-mouse IRDye 680LT-conjugated secondary antibody in TBS. Images were taken using the Odyssey CLx and processed with Image Studio version 2.0 (LiCor Biosciences). Protein input for sphingostrips and PIPstrips was analyzed by SDS-PAGE and Western blot as described above. Fold increase in syntaxin 6-lipid binding was determined by normalization of densitometry as described below.

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.
