Immunoprecipitation - KAP1 antibody (ab10484)

Detection of Human KAP1 by Western Blot and Immunoprecipitation. Samples: A. Whole cell lysate (50 ug) from normal 293T cells (E) or 293T cells transiently transfected with a human KAP1 construct (T). B. Whole cell lysate (0.5 mg) from normal 293T cells. Antibodies: ab10484 used at 1 ug/ml for WB (A) or 2 ug/0.5 mg lysate for IP (B). Immunoprecipitated KAP1 was detected using a KAP1 antibody from another source. Detection: Chemiluminescence with a 10 minute (A) or 1 minute (B) exposure.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)-KAP1 antibody(ab10484)

Ab10484 staining normal human spleen. Staining is localized to the nucleus.
Left panel: with primary antibody at 2 ug/ml. Right panel: isotype control.
Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS), then incubated with primary antibody for 20 minutes, and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Immunocytochemistry/ Immunofluorescence-KAP1 antibody(ab10484)

ICC/IF image of ab10484 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab10484, 1µg/ml) overnight at +4ºC. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - KAP1 antibody (ab10484)

ab10484 staining KAP1 in murine coronal brain tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with paraformaldehyde and permeabilized using 1% Triton. Samples were then blocked with 5% serum for 1 hour at 25ºC followed by incubation with the primary antibody at 2µg/ml for 16 hours at 4ºC. An Alexa-Fluor 488-conjugated donkey anti-rabbit polyclonal was used as secondary antibody at a 1/1000 dilution.
