Anti-PKR antibody [Y117] - BSA and Azide free

• ICC/IF

Unknown

Immunocytochemistry/ Immunofluorescence - Anti-PKR antibody [Y117] - BSA and Azide free (AB239817)

ab32506 staining PKR in MCF-7 (human breast carcinoma) cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. Samples were incubated with primary antibody at a dilution of 1/100. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody. ab7291 and ab150120 were used as counterstains for primary antibody ab32506 and secondary antibody ab150077 respectively and DAPI was used as a nuclear counterstain.

Negative control 1 : Rabbit primary antibody and anti-mouse secondary antibody (ab150120)
Negative control 2 :  Mouse primary antibody (ab7291) and anti-rabbit secondary antibody (ab150077)

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32506).

• Flow Cyt (Intra)

Unknown

Flow Cytometry (Intracellular) - Anti-PKR antibody [Y117] - BSA and Azide free (AB239817)

Intracellular Flow Cytometry analysis of MCF-7 (human breast carcinoma) cells labeling PKR with purified ab32506 at 1/20 dilution (10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor^® 488) (1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32506).

• IHC-P

Unknown

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PKR antibody [Y117] - BSA and Azide free (AB239817)

Immunohistochemical analysis of paraffin-embedded human colon carcinoma using unpurified ab32506 at 1/100 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32506).

• ICC/IF

Unknown

Immunocytochemistry/ Immunofluorescence - Anti-PKR antibody [Y117] - BSA and Azide free (AB239817)

Immunofluorescent staining of HeLa cells using unpurified ab32506 at 1/250 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32506).

• IHC-P

Unknown

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PKR antibody [Y117] - BSA and Azide free (AB239817)

ab32506 staining PKR in human liver carcinoma 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 1/100. 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.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32506).

• ICC/IF

Unknown

Immunocytochemistry/ Immunofluorescence - Anti-PKR antibody [Y117] - BSA and Azide free (AB239817)

ab32506 staining PKR in wild-type HAP1 cells (top panel) and PKR knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab32506 at 1/400 dilution and ab7291 at 1ug/ml concentration overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to Mouse IgG (Alexa Fluor® 594) (ab150117) at 2ug/ml (shown in pseudo-color red). Nuclear DNA was labelled in blue with DAPI.

This product also gave a positive signal under the same testing conditions in HAP1 cells fixed with 4% formaldehyde (10 min).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32506).

• IP

Unknown

Immunoprecipitation - Anti-PKR antibody [Y117] - BSA and Azide free (AB239817)

ab32506 immunoprecipitating PKR. 10μg of cell lysate was incubated with primary antibody at a dilution of 1/40 and VeriBlot for IP Detection Reagent (HRP) (ab131366) at a dilution of 1/10000.

Lane 1 : HEK293 (human embryonic kidney) whole cell lysate (10ug)
Lane 2 : HEK293 (human embryonic kidney) whole cell lysate
Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab32506 in HEK293 (human embryonic kidney) whole cell lysate

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32506).
