- Western blotting analysis of human vimentin using mouse monoclonal antibody VI-RE/1 on lysates of MOLT-4 cell line (low expression), U87 cell line (positive) and Raji cell line (negative control) under non-reducing and reducing conditions. Nitrocellulose membrane was probed with 2µg/mL of mouse anti-vimentin Monoclonal antibody (Product # MA1-19319) followed by IRDye800-conjugated anti-mouse secondary antibody. A specific band was detected for vimentin at approximately 55kDa.

- Western blot analysis was performed on Whole cell extracts (30 µg lysate) of HeLa (Lane 1), A-431 (Lane 2), SHSY-5Y (Lane 3), Hep G2 (Lane 4) and NIH/3T3 (Lane 5). The blot was probed with Anti-Vimentin Monoclonal Antibody (Product # MA1-19319, 1:2000 dilution) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.25 µg/ml, 1:4000 dilution). A 54 kDa band corresponding to Vimentin was observed across all the human cell lines positive for Vimentin (Lanes 1 and 3) but not mouse cell line (Lane 5), while this band was absent in the cell lines which do not express Vimentin protein (Lanes 2 and 4).

- Immunofluorescence analysis of Vimentin was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Vimentin Mouse Monoclonal Antibody (Product # MA1-19319) at 5 µg/mL in 0.1% BSA and incubated overnight at 4 degree Celsius and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic, cytoskeletal and nuclear localization. Panel e represents negative control, A-431 cells. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

- Figure 4 HMLE-Snail cells gain CD31 expression and promote acquisition of mesenchymal traits by admixed MCF-7 cells. RFP/luciferase-labeled MCF-7 cells (0.5 x 10 6 ) were co-mixed with 0.5 x 10 6 MCF-7, HMLE-vector, or HMLE-Snail cells, and orthotopically implanted into female NOD/SCID mice. Ten weeks post implantation, the tumors were harvested and processed for immunofluorescent staining. n = 5 mice per group. ( A , B ) Tumor core sections were co-stained with antibodies directed against RFP (red) and either E-cadherin (A) or vimentin (B), both pseudo-colored green. Nuclei were counterstained with DAPI (blue). Right panels are merged images of individual channels. Note the progressive reduction of E-cadherin expression, commensurate with the attenuation of the honeycomb-like membrane staining pattern across these tumor cores and the inversely-correlated augmented vimentin staining. ( C ) Sections from the tumor cores were co-stained with antibodies directed against the SV40 large-T antigen (green) and human CD31 (red). Nuclei were counterstained with DAPI (blue). Right panels are merged images of individual channels. Arrows indicate SV40 large-T antigen/CD31 double-positive cells lining the lumens of vascular structures in tumors formed by admixed MCF-7/HMLE-Snail cells. Boxed areas represent high-magnification images of selected encircled areas. Scale bars, 100 mum. Representative images are shown.
