Microscopic Imaging of α-Tubulin in MDA-MB-231 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
MDA-MB-231 cells (2.4 × 104 cells/well) were grown on an 8-well chamber slide (Lab-Tech, Waltham, USA) for 24 h prior to treatment with reagents. Cells were treated for 24 h with compound 5 or DMSO as a control for 24 h. Cells were fixed in 4% paraformaldehyde in PBS and permeabilized with 0.5% Triton X-100 in PBS. Fixed cells were labeled with mouse monoclonal antibody to α-tubulin (B5-1-2, Sigma, St. Louis, MO, USA) followed by FITC-conjugated antibody to mouse IgG (Sigma) [31 (link)]. Nuclei were labeled with DAPI (Sigma). Fluorescence labeled cells were observed using confocal microscope (LSM700, Zeiss, White Plains, NY, USA) controlled by ZEN (black edition) software (Zeiss). Confocal images were stacked and merged using ZEN (black edition) software. Final images were prepared using Adobe Photoshop.

MDA-MB-231 cells were seeded in the 8-well chamber slide (Lab-Tech) 24 h prior to treatment with compounds. After 24 h treatment, cells were fixed with 4% paraformaldehyde in PBS followed by permeabilization with 0.5% Triton-X100. Cells were then probed with antibody to α-tubulin (B5–1-2, Sigma) followed by FITC-conjugated antibody to mouse IgG (Sigma). Nuclei were labeled with 4′,6-diamidino-2-phenylindole (DAPI) (Sigma). Microtubules were detected using a confocal microscope (Zeiss, LSM700) controlled by ZEN software (Zeiss). Final images were reconstructed from 12−18 sections acquired at 0.6−1 μm intervals and merged using ZEN (black edition) software. Experiments were repeated at least twice for each compound at each concentration. Final images were prepared using Adobe Photoshop CS6.

Immunofluorescent Staining of Cytoskeletal Structures

KB-VIN cells were seeded in an 8-well chamber slide (Lab-Tech) at a density of 1 × 105 per mL and incubated overnight. After 24 h of treatment with tested compounds, the cells were fixed with 4% paraformaldehyde in PBS for 10 min followed by permeabilization with 0.5% Triton X-100 in PBS for 5 min at room temperature. Cells were then blocked with 5% normal goat serum in 1% BSA in washing buffer (0.01% Tween 20 in PBS) for 30 min. Cells were labeled with monoclonal antibody to α-tubulin (T5168, clone B-5–1-2, Sigma-Aldrich) for 2 h followed by fluorescein isothiocyanate (FITC)-labeled anti-mouse IgG secondary antibody (F5262, Sigma-Aldrich) for 1 h. F-actin was stained with tetramethylrhodamine (TRITC)-labeled phalloidin (P1951, Sigma-Aldrich) for 30 min while DNA was stained with 4’,6-diamidino-2-phenylindole (DAPI) (D9542, Sigma-Aldrich) for 5 min. Stained cells were mounted with Vectashield (H-1000, Vector Laboratories). The images were captured by confocal fluorescence microscope (Zeiss LSM700) (Laser lines: 405 nm for DAPI, 488 nm for FITC, and 555 nm for TRITC) operated by ZEN software (Zeiss). Final images were analyzed by ZEN light and processed with Photoshop 7 (Adobe).

Immunocytochemical Analysis of Microtubule and Mitotic Markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunocytochemical analysis was performed as previously described [26 (link)]. KB-VIN cells were grown on an 8-well chamber slide (Lab-Tech) for 24 h prior to treatment with the compound at a concentration of three-fold IC50. CA-4 was used at 0.2 μM (Figure 2A and Supporting Information, Supplementary Figure S1). After treatment of cells with the agent for 24 h, cells were fixed with 4% paraformaldehyde in PBS and permeabilized with 0.5% Triton X-100 in PBS. Fixed cells were labeled with mouse monoclonal antibody to α-tubulin (B5-1-2, Sigma) and rabbit IgG to Ser10-phosphorylated histone H3 (p-H3) (#06570, EMD Millipore), followed by FITC-conjugated antibody to mouse IgG (Sigma) and Alexa Fluor 549-conjugated antibody to rabbit IgG (Life Technologies). Nuclei were labeled with DAPI (Sigma). Fluorescently-labeled cells were observed using a confocal microscope (Zeiss, LSM700) with ZEN (black edition) software (Zeiss). The 15~20 optical sections acquired at 0.5~1 µm intervals were stacked and reconstructed using ZEN (black edition) software. Experiments were repeated at least twice for each compound. Final images were prepared using Adobe Photoshop CS3.

Cells (1 × 104/well) were seeded on 8-well chamber slides (Lab-Tech) after transfection. The cells were fixed, permeated and blocked. Then, they were incubated with the following antibodies: anti-VIM (1:200, Abcam), anti-ITGAV (1:1000, Cell Signaling Technology), anti-ITGB1 (1:1000, Cell Signaling Technology), anti-ITGB3 (1:500, Cell Signaling Technology) or anti-CD47 (1:200, Abcam). The secondary antibody, Alexa Fluor 488-conjugated goat anti-mouse IgG or anti-rabbit IgG (1:500, Invitrogen), was applied for 1 hour. Slides were mounted with antifading solution containing 4′-6′-diamidino-2-phenyl-indole (Vector Laboratories). Images were taken using a confocal microscope (Zeiss). All experiments were conducted in triplicate.

The expression levels of carbonic anhydrase 9 (CA9), vimentin, and pan-keratin were compared by using immunofluorescence. Cancer cells and normal cells from patients were cultured in 8-well chamber slides (Labtech, East Sussex, UK). Each cell was seeded for 5 hours after trypsin treatment and removal of Matrigel. Cells were fixed with 4% paraformaldehyde solution for 10 minutes and then washed with PBS. Cells were then permeated in 0.5% Triton X-100 in PBS for 5 minutes, blocked in 5% bovine serum albumin (BSA) in PBS for 20 minutes, and incubated with diluted primary antibodies to CA9 (1:100; Novus Biologicals, Littleton, CO, USA), vimentin, and pan-keratin (Cell Signaling Technology, Danvers, MA, USA) in 5% BSA at 4℃ for 16 hours. Cells were washed with PBS and then incubated with secondary antibodies tagged with Alexa Fluor 488 or 594 (Molecular Probes, Eugene, OR, USA) at 25℃ for 1 hour (1:200). Images were acquired by laser scanning confocal microscopy (laser scanning microscope [LSM] Meta 700; Carl Zeiss, Oberkochen, Germany) and analyzed with LSM Image Browser software.

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.
