Anti tenascin c antibody

After electrophoresis of total cell proteins, samples were immunoblotted as previously reported^{82 (link),83 (link)}. Membranes were then incubated overnight at 4 °C with the following polyclonal antibodies [dilution, -fold]: anti-VCAM1 antibody (Abcam,) [5000], anti-E-Cadherin antibody (BS Transduction Laboratories) [1000], anti-tenascin-C antibody (Santa Cruz Biotechnology, Santa Cruz CA) [500], anti- NPHS2 antibody (Abcam) [5000], anti-nephrin antibody (Abcam) [5000] and anti-tubulin (Sigma–Aldrich, Saint Louis, MO [5000]. Anti-vimentin (Santa Cruz Biotechnology) [1000], anti-cofilin-1 (Santa Cruz Biotechnology) [1000], anti-vinculin (Santa Cruz Biotechnology) [1000], anti-ILK (Santa Cruz Biotechnology) [1000], anti-β-catenin (Santa Cruz Biotechnology) [2000].
Coomassie staining (Sigma) of the membrane was used as an internal loading control. Blots were analyzed by densitometric scanning with Image J. Western blot studies in cultured cells were performed in at least three independent experiments, and a representative figure is shown.

SCC13 cells (1 × 10⁶ cells) were admixed with HDFs (5 × 10⁵ cells) with shRNA-mediated silencing of PDCD4 or control in 150 μl of growth factor-reduced matrigel (BD Bioscience) and intra-dermally injected into the back skin of 6-week-old NOD/SCID mice (Taconic Farms Inc.) as previously described [30 (link)]. For the ear injection, SCC13 cells (1 × 10⁵ cells) were admixed with equal numbers of HDFs with shRNA-mediated silencing of PDCD4 or control. Cells were resuspended in 3 μl of Hanks’ balanced salt solution and then injected intradermally into the left and right tip of the ear dermis of 10-week-old NOD/SCID mice using a Hamilton microsyringe fitted with 33 gauge needle as performed in [3 (link)]. Mice were sacrificed 3 weeks after injection and tumors were removed for analysis.
Tissue immunofluorescence was performed as before [2 (link), 3 (link)]. Anti- ki67 antibody, anti-Vimentin antibody (Abcam), anti-p63 antibody (Santa Cruz Biotechnology), anti-Involucrin antibody (Sigma), anti-Periostin antibody (Abcam), anti-Tenascin C antibody (Santa Cruz Biotechnology), and anti-αSMA antibody (Santa Cruz Biotechnology) were used. Quantification of all images of tissue immunofluorescence staining was performed using ImageJ and Adobe Photoshop software.
All animal studies were performed following the approved Institutional animal protocol procedure (IACUC-MGH).
