Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Fibronectin antibody [EP-5] - BSA and Azide free (AB281576)

This data was developed using ab281574 the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of paraffin-embedded Human colon cancer tissue labeling Fibronectin with ab281574 at 1/100 (10.52 ug/ml) dilution followed by a ready to use LeicaDS9800 (Bond® Polymer Refine Detection) . Positive staining in stromal cells of human colon cancer.The section was incubated with ab281574 for 30 mins at room temperature.The immunostaining was performed on a Leica Biosystems BOND® RX instrument Counterstained with Hematoxylin.

Secondary antibody only control : Secondary antibody is a ready to use LeicaDS9800 (Bond® Polymer Refine Detection) .

Heat mediated antigen retrieval with Citrate buffer (pH 6.0, epitope retrieval solution 1) for 20 mins

Western blot - Anti-Fibronectin antibody [EP-5] - BSA and Azide free (AB281576)

This data was developed using 281574, the same antibody clone in a different buffer formulation.

Blocking and diluting buffer and concentration : ntercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS

The expression molecular weight observed is consistent with what has been described in the literature (PMID : 28367057).

Lanes 1-3 : Merged signal (red and green). Green - ab281574 observed at 285kDa. Red - loading control ab52901(Rabbit monoclonal [EP1331Y] to beta Tubulin) observed at 50 kDa.

Lanes 1-2 : ab281574 Anti-Fibronectin antibody was shown to react with Fibronectin in HAP1 cells in Western blot. Loss of signal was observed when Fibronectin knockout sample was used. Wild-type and Fibronectin knockout samples were subjected to SDS-PAGE.

ab281574 and Anti-beta Tubulin antibody [EP1331Y] - Loading Control (ab52901) were incubated at 4℃ overnight at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 680CW) preadsorbed (ab216777) and Goat anti-Mouse IgG H&L (IRDye® 800RD) preadsorbed (ab216772) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.
