1/250 - 1/500. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. (heat up to 98 degrees C, below boiling, and then let cool for 10-20 min.)
1/100 - 1/1000. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
For unpurified use at 1/100 - 1/250
Organizes filamentous actin into bundles with a minimum of 4.1:1 actin/fascin ratio. Plays a role in the organization of actin filament bundles and the formation of microspikes, membrane ruffles, and stress fibers. Important for the formation of a diverse set of cell protrusions, such as filopodia, and for cell motility and migration.
Belongs to the fascin family.
Composed of four beta-trefoil domains.
Phosphorylation on Ser-39 inhibits the actin-binding ability of fascin.
Immunocytochemistry/Immunofluorescence analysis of U87-MG (human glioblastoma) labelling Fascin with purified ab126772 at 1/500. Cells were fixed with 100% methanol. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG (ab150077) at dilution of 1/1000 was used as the secondary antibody. Nuclei couterstained with DAPI (blue).
Secondary Only Control: PBS was used instead of the primary antibody as the negative control.
Overlay histogram showing HeLa cells stained with ab126772 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab126772, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
