PurityImmunogen affinity purified
Purification notesThe antibody was purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated Inhibitor-2. The final product is generated by affinity chromatography using an Inhibitor-2 -derived peptide that is phosphorylated at threonine 72.
Our Abpromise guarantee covers the use of ab27850 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000. Predicted molecular weight: 23 kDa.|
FunctionInhibitor of protein-phosphatase 1.
Sequence similaritiesBelongs to the protein phosphatase inhibitor 2 family.
modificationsPhosphorylation on Thr-73 by GSK3 activates PP1 by dissociating the PP1-PPP1R2 complex (By similarity). Phosphorylation on Ser-44 by ATM activates PP1 by dissociating the PP1-PPP1R2 complex.

Immunocytochemistry/Immunofluorescent analysis of A431 cells treated with Nocodazole for 24 hours, staining Protein phosphatase 1 inhibitor subunit 2 at 1/250 dilution, followed by Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate at 1/2000 dilution (green). Cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X 100 for ten minutes, and blocked with 1% BSA for one hour at room temperature. Nuclei were counterstained with DAPI (blue). F-actin was stained with Rhodamine Phalloidin (red).
Negative controls are untreated A431 cells (e) and a secondary only antibody control (f).
Immunocyutochemistry/Immunofluroescence analysis of HeLa cells staining Protein phosphatase 1 inhibitor subunit 2 with ab27850 (green). Cells were grown on a chamber slide and fixed in cold 10% trichloroacetic acid for 10 minutes, rinsed in TBS and permeabilized with 0.1% Triton-X-100 for 15 minutes.
