重组Anti-Sumo 1抗体[Y299] - ChIP Grade (ab32058)

Chromatin was prepared from SK-OV-3 (Human ovarian cancer cell line) cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 5µg of ab32058 (red, and 20µl of Anti rabbit IgG sepharose beads. 5μg of rabbit normal IgG was added to the beads control (grey).  The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).

ChIP was performed according to the literature (PMID: 23770046).

Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: Empty
Lane 3: Sumo 1 knockout HAP1 whole cell lysate (20 µg)
Lane 4: Empty

Lanes 1 - 4: Merged signal (red and green). Green - ab32058 observed at 16 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab32058 was shown to react with Sumo 1 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when Sumo 1 knockout samples were used. Wild-type and Sumo 1 knockout samples were subjected to SDS-PAGE. Samples were incubated with ab32058 and ab8245 (Mouse anti GAPDH loading control) overnight at 4°C at a 1/1000 dilution and 1/10000 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 1/10000 dilution for 1 hour at room temperature before imaging.

Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. Samples were incubated with primary antibody at a dilution of 1/500. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000. ab195889 was used as a counterstain for primary antibody ab133645 at 1/200. DAPI was used as a nuclear counterstain and PBS as a negative control.

ab32058 staining Sumo 1 in mouse kidney tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and antigen retrieval was by heat mediation in a EDTA buffer. Samples were incubated with primary antibody at a dilution of 1/250. A goat anti-rabbit IgG H&L (HRP) ab97051 was used as the secondary antibody at a dilution of 1/500.

Negative control 1: PBS in place of primary antibody.

Cells were fixed with 4% paraformaldehyde and the sample was incubated with the primary antibody at a dilution of 1/20. A goat anti rabbit IgG (Alexa Fluor^® 488) at a dilution of 1/2000 was used as the secondary antibody.
