All lanes : Anti-Interferon alpha 2 antibody [EPR19074] (ab196221) at 1/5000 dilution
Lane 1 : HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) transfected with an empty vector, containing a GFP-Myc-tag, whole cell lysate
Lane 2 : HEK-293T transfected with Interferon alpha 2 expression vector containing a GFP-Myc-tag, whole cell lysate
Lysates/proteins at 10 µg per lane.
Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution
Developed using the ECL technique.
Predicted band size: 22 kDa
Observed band size: 50 kDa why is the actual band size different from the predicted?
Exposure time: 3 secondsBlocking and dilution buffer: 5% NFDM/TBST.
The molecular mass observed is due to the presence of the GFP epitope tag on full length IFN alpha 2.

Interferon alpha 2 was immunoprecipitated from 0.35 mg of HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate using ab196221 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab196221 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10,000 dilution.
Lane 1: HEK-293T (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate 10 μg (Input).
Lane 2: ab196221 IP in HEK-293T (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab196221 inHEK-293T (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 1 second.The molecular mass observed is due to the presence of the GFP epitope tag on full length IFN alpha 2.

Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol-permeabilized HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag cell line) cells labeling Interferon alpha 2 with ab196221 at 1/600 (red) compared with Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730)(black) and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (blue).
Goat Anti-Rabbit IgG H&L (Alexa Fluor® 647) (ab150079), at 1/2000 dilution was used as the secondary antibody.

Immunocytochemical analysis of agarose-embedded HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) (transfected with Interferon alpha 2 (pcDNA3.1 (+)-EGFP-Myc)) cells labeling Interferon alpha 2 with ab196221 at 1/1000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use secondary antibody. Positive staining on HEK-293T cells transfected with Interferon alpha 2 (pcDNA3.1 (+)-EGFP-Myc) (image A); and no staining on HEK-293T cells without transfection (image B). Counterstained with hematoxylin.
Secondary antibody only control: Used PBS instead of ab196221, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use.

Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) (transfected with either GFP-tagged Interferon alpha 2 expression vector or empty GFP expression vector) cells labeling Interferon alpha 2 with ab196221 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 647) (ab150079) secondary antibody at 1/1000 dilution. Confocal image showing cytoplasmic staining in HEK-293T cells transfected with GFP-tagged Interferon alpha 2 expression vector.
The nuclear counterstain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) at 1/200 dilution (red).
Secondary antibody only control: Used PBS instead of ab196221, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 647) (ab150079) secondary antibody at 1/1000 dilution. -
