Recombinant Anti-alpha 1 Fetoprotein antibody [RM1011] (ab284388)

This data was developed using ab284388, the same antibody clone in a different buffer formulation.

Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% TritonX-100 permeabilized HepG2 cells labelling alpha 1 Fetoprotein with ab284388 at 1/50 dilution, followed by ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) antibody at 1/1000 (2µg/mL) dilution (Green). ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor® 594) was used to counterstain tubulin at 1/200 2.5µg/mL dilution (Red). The Nuclear counterstain was DAPI (Blue).

Confocal image showing cytoplasmic staining in HepG2 cells is observed.

Secondary antibody only control: Secondary antibody is ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) at 1/1000 (2µg/mL) dilution.

Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% TritonX-100 permeabilized Hepa1-6 cells labelling alpha 1 Fetoprotein with ab284388 at 1/50 dilution, followed by ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed antibody at 1/1000 2µg/mL dilution (Green). ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor® 594) was used to counterstain tubulin at 1/200 (2.5µg/mL) dilution (Red). The Nuclear counterstain was DAPI (Blue).

Confocal image showing increased cytoplasmic staining in Hepa1-6 cells treated with Brefeldin A (300 ng/ml) for 24 h is observed.

Secondary antibody only control: Secondary antibody is ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed at 1/1000 (2µg/mL) dilution.

Immunohistochemical analysis of paraffin-embedded Human hepatic carcinoma tissue labelling alpha 1 Fetoprotein with ab284388 at 1/2000 (0.231 µg/mL) followed by a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Positive staining on human hepatic carcinoma. The section was incubated with ab284388 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument Counterstained with Hematoxylin.

Secondary antibody only control: Secondary antibody is a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection).

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.

Negative control: No staining on human liver.

Immunohistochemical analysis of paraffin-embedded Human liver tissue labelling alpha 1 Fetoprotein with ab284388 at 1/2000 (0.231 µg/mL) followed by a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). The section was incubated with ab284388 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument Counterstained with Hematoxylin.

Secondary antibody only control: Secondary antibody is a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection).

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.

Blocking and diluting buffer and concentration: 5% NFDM/TBST

Negative control: MDA-MB-231.

Exposure time: Lane 4-5: 26 seconds ; Others: 5 seconds

Flow cytometric analysis of 4% paraformaldehyde fixed 90% methanol permeabilized HepG2 (Human hepatocellular carcinoma epithelial cell) cells labelling alpha 1 Fetoprotein with ab284388 at 1/500 dilution Right (Red) compared with a Rabbit monoclonal IgG (ab172730) / Left isotype control. A Goat Anti-Rabbit IgG (Alexa Fluor® 488, ab150081) at 1/2000 dilution was used as the secondary antibody.

Flow cytometric analysis of 4% paraformaldehyde fixed 0.1% Tween-20 permeabilized Hepa1-6 (Mouse hepatoma epithelial cell) treated with 300ng/ml BFA for 24h (Right) / Untreated control (Left) cells labelling alpha 1 Fetoprotein with ab284388 at 1/500 dilution. A Goat Anti-Rabbit IgG (Alexa Fluor® 488, ab150081) at 1/2000 dilution was used as the secondary antibody.

alpha 1 Fetoprotein was immunoprecipitated from 0.35 mg HepG2 (Human hepatocellular carcinoma epithelial cell) whole cell lysate 10ug with ab284388 at 1/30 dilution (2 µg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab284388 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP)(ab131366) was used at 1/5000 dilution.
