    Thermo Fisher tritonx 100
    The effect of common buffer components on the LRET assay. Common buffer components were tested for their ability to alter the interaction 10 nM Tb-core with 20 nM F-σ70 after a 1-hour incubation at 22°C. The average value of A 520 /A 490 for three replicates was determined and normalized to a no-treatment control with a buffer containing 50 mM Tris-HCl pH 7.9, 5% glycerol, and 100 mM NaCl. The error bars represent the normalized standard deviation for a sample size of 4. A) Common solvents (DMSO, ethanol, and methanol) were tested in a range of 0–50% (v/v). B) The non-ionic detergents <t>TritonX-100</t> and Tween-20 were tested from 0–5% (v/v). C) Glycerol was tested from 2.5–50% (v/v). The minimum glycerol level (2.5%) was due to the glycerol in the buffer of the proteins. D) Bovine serum albumin (BSA) and MgCl 2 were tested from 0–1000 µg/mL and 0–500 mM, respectively.

    Membrane expression and functionality of hLDLR expressed by the CHO-hLDLR-EGFP cell line. (A) Representative confocal photomicrographs of immunostained CHO-hTfR-EGFP (negative control) and CHO-hLDLR-EGFP cells (green) with an anti-LDLR antibody diluted at 1/100 (red) following triton <t>X100</t> permeabilization of the cell membrane. Cell nuclei are labeled with Hoechst#33258 at 0.5 μg/mL (blue). Co-labeling appears in yellow in the merged pictures. Only the cells with stable expression of the hLDLR-EGFP construct express the membrane receptor. (B) Representative confocal photomicrographs of CHO-hTfR-EGFP and CHO-hLDLR-EGFP cells (green) after a 10 min incubation period with DiI-LDL 15 μg/mL (red). Cell nuclei are labeled with Hoechst#33258 (blue). Co-labeling appears in yellow in the merged pictures. DiI-LDL is essentially bound to the CHO-hLDLR-EGFP cells indicating that the hLDLR-EGFP chimera receptor binds its ligand. (C) Western blots performed on cell membrane preparations of CHO cells expressing hLDLR-EGFP, rLDLR-EGFP and mLDLR-EGFP compared to CHO WT, using anti-hLDLR (1/800) and anti-rat and mouse LDLR antibodies (1/1000). These bands are also labeled with an anti-EGFP antibody. Bands of 140 kDa and 190 kDa correspond respectively to the immature and mature LDLR-EGFP fusion proteins (arrows). Actin was used to check loading of equal amounts of protein.

B) The non-ionic detergents TritonX-100 and Tween-20 were tested from 0–5% (v/v). C) Glycerol was tested from 2.5–50% (v/v). The minimum glycerol level (2.5%) was due to the glycerol in the buffer of the proteins. D) Bovine serum albumin (BSA) and MgCl 2 were tested from 0–1000 µg/mL and 0–500 mM, respectively.

    Effect of Triton X-100 on the migration of single stranded DNA in polyacrylamide gels. The gel illustrates the smearing of single stranded DNA when loaded on polyacrylamide gels in the presence of Triton X-100. The DNA sample was the same in all lanes and contained a labeled single stranded circle of 235 nucleotides. Two minor bands that show no smearing most probably correspond to contaminating double stranded DNA, as smearing was always observed with many different single strands. Three different brands of Triton-X100 denoted T1–T3 were tested at a final concentration of 0.05%: T1 and T2 were ordinary grade, T3 was highly purified, oxidant-free Triton-X100, sold in glass ampules sealed under nitrogen (Pierce). Lane 1: control, no Triton-X100 added; lane 2: deionized T1; lane 3: T1, untreated; lane 4: T1, heat-treated; lane 5: T1, SDS added at a concentration of 0.005%; lane 6: T3, untreated; lane 7: T1, washed with a 5M NaCl solution; lane 8: T2, untreated. Note that addition of SDS to the samples before loading the gel was a very efficient way to suppress smearing (lane 5).

    IFITM3 expression inhibits SFV capsid release . A) SFV (200 pfu/cell) was bound to cells for 1 h at 4°C prior to incubation at 37°C for the indicated times. At each time point the cells were fixed and permeabilized with 0.1% Triton‐X100 and labeled with serum against the SFV capsid, which was detected with AF594. Confocal sections are displayed. Following internalization, virus particles were detected in cells, indicated by the typical punctate association of virus with endosomes. By 40 min after warm‐up diffuse cytosolic fluorescence was seen in A549 cells, indicating release of the viral capsid protein to the cytosol. In A549 cells treated with 10 µ m monensin, and in OS‐IFITM3‐HA expressing cells, the staining remains associated with puncta and the cytosolic staining was not observed even at 60 min after warm‐up. Nuclei were detected with Hoechst staining. Scale bar represents 15 µm. B) Quantification of cytosolic fluorescence and significance testing is described in Materials and Methods . The data are from three independent infections with 3–7 images taken at each condition, with a total of at least 60 cells analyzed per cell line, per condition. Data presented is the average fluorescence intensity, normalized to the background intensity at 0 min of warming. *p

    Article Snippet: Immunofluorescence staining and microscopy and flow cytometry Immunofluorescence staining and microscopy was performed as previously described with the exception that 0.1% Triton‐X100 (Tx100, Sigma) was used for permeabilization in experiments to detect the SFV capsid protein.

    Membrane expression and functionality of hLDLR expressed by the CHO-hLDLR-EGFP cell line. (A) Representative confocal photomicrographs of immunostained CHO-hTfR-EGFP (negative control) and CHO-hLDLR-EGFP cells (green) with an anti-LDLR antibody diluted at 1/100 (red) following triton X100 permeabilization of the cell membrane. Cell nuclei are labeled with Hoechst#33258 at 0.5 μg/mL (blue). Co-labeling appears in yellow in the merged pictures. Only the cells with stable expression of the hLDLR-EGFP construct express the membrane receptor. (B) Representative confocal photomicrographs of CHO-hTfR-EGFP and CHO-hLDLR-EGFP cells (green) after a 10 min incubation period with DiI-LDL 15 μg/mL (red). Cell nuclei are labeled with Hoechst#33258 (blue). Co-labeling appears in yellow in the merged pictures. DiI-LDL is essentially bound to the CHO-hLDLR-EGFP cells indicating that the hLDLR-EGFP chimera receptor binds its ligand. (C) Western blots performed on cell membrane preparations of CHO cells expressing hLDLR-EGFP, rLDLR-EGFP and mLDLR-EGFP compared to CHO WT, using anti-hLDLR (1/800) and anti-rat and mouse LDLR antibodies (1/1000). These bands are also labeled with an anti-EGFP antibody. Bands of 140 kDa and 190 kDa correspond respectively to the immature and mature LDLR-EGFP fusion proteins (arrows). Actin was used to check loading of equal amounts of protein.

    Article Snippet: In order to detect the Fc conjugates in tissues of injected mice, organs (liver and adrenals), were mechanically dissociated in PBS 0.1% Triton X100, snap frozen, thawed and sonicated 10 x 10 s. Protein content in membrane and tissue extracts were quantified using the BioRad DC Protein Assay (Bio-Rad, Hercules, CA, USA) following manufacturer’s instructions.
