Flow Cytometry (Intracellular) - Anti-SPARC antibody [EPR20121] (AB207743)

Intracellular flow cytometric analysis of 4% paraformaldehyde-fixed A-375 (Human malignant melanoma cell line) cells labeling SPARCwith ab207743 at 1/70 dilution (red) compared with a rabbit monoclonal IgG isotype control (ab172730; black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody; blue). Goat anti rabbit IgG (Alexa Fluor^® 488) at 1/2000 dilution was used as the secondary antibody.

Immunoprecipitation - Anti-SPARC antibody [EPR20121] (AB207743)

SPARC was immunoprecipitated from 0.35 mg of A-375 (Human malignant melanoma cell line) whole cell lysate with ab207743 at 1/40 dilution.

Western blot was performed from the immunoprecipitate using ab207743 at 1/1000 dilution.

VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

Lane 1 : A-375 whole cell lysate, 10μg (Input).

Lane 2 : ab207743 IP in A-375 whole cell lysate.

Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab207743 in A-375 whole cell lysate.

Blocking and dilution buffer and concentration : 5% NFDM/TBST.

Exposure time : 3 minutes.

Western blot - Anti-SPARC antibody [EPR20121] (AB207743)

Lanes 1 - 2 : Merged signal (red and green). Green - ab207743 observed at 35 kDa. Red - loading control, ab130007, observed at 130 kDa.

ab207743 was shown to recognize SPARC in wild-type HAP1 cells as signal was lost at the expected MW in SPARC knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and SPARC knockout samples were subjected to SDS-PAGE. ab207743 and ab130007 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
