Our Abpromise guarantee covers the use of ab14824 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: 1/250 - 1/1000. Predicted molecular weight: 42 kDa.
IHC-P: Use at a concentration of 4 µg/ml.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionEnzyme with a broad specificity. Negatively regulates TGF-beta signaling through dephosphorylating SMAD2 and SMAD3, resulting in their dissociation from SMAD4, nuclear export of the SMADs and termination of the TGF-beta-mediated signaling.
Sequence similaritiesBelongs to the PP2C family.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: PPM1A knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: Jurkat cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab14824 observed at 42 kDa. Red - loading control, ab18251, observed at 52 kDa.
ab14824 was shown to specifically react with PPM1A when PPM1A knockout samples were used. Wild-type and PPM1A knockout samples were subjected to SDS-PAGE. ab14824 diluted to 1/250 and ab18251 (loading control to alpha Tubulin) diluted to 1/10000 were incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
Western blot analysis of mouse liver cytosol extract using ab14824 at a dilution of 1/250. Proteins were visualised using a goat anti-mouse secondary antibody conjugated to HRP and a DAB detection system.

Ab14824 staining human colon. Staining is localised to cytoplasm.
Left panel: with primary antibody at 4ug/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 antigen retrieval 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.
