    This data was developed using ab275390, the same antibody clone in a different buffer formulation.

    Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HepG2 (human hepatocellular carcinoma epithelial cell) cells labelling COL18A1 with ab275390 at 1/50 dilution, followed by ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) antibody at 1/1000 dilution (Green). Confocal image showing cytoplasmic staining in HepG2 cells.  Negative control: U937 cell (PMID: 15451191). is observed. ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor® 594) was used to counterstain tubulin at 1/200 dilution (Red). The Nuclear counterstain was DAPI (Blue).

    Secondary antibody only control: Secondary antibody is ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) at 1/1000 dilution.

    Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol-permeabilized U-937 (human histiocytic lymphoma monocyte, Left) / HepG2 (human hepatocellular carcinoma epithelial cell, Right) cells labelling COL18A1 with ab275390 at 1/500 dilution (Red) compared with a Rabbit monoclonal IgG (ab172730) isotype control (Black) and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue).

    A Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.

    COL18A1 was immunoprecipitated from 0.35 mg Huh7 (human hepatocellular carcinoma epithelial cell) whole cell lysate with ab275390 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab275390 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP)(ab131366) was used at 1/5000 dilution.

    Western blot was performed with the immuno-precipitate of ab275390, probed with ab275390 at 1/1000 dilution (Panel A) or ab207162 at 1/1000 dilution (Panel B). The 23- and 28-kDa fragments were recognized by ab207126, suggesting that these fragments are part of the C-terminal non-collagenous domain containing endostatin.
