Serum starved SR cells either untreated (positive control, filled histogram), or treated with 4,5,6,7-Tetrabromobenzotriazole (TBB) (negative control, open histogram) were fixed and permeabilized using True-Phos™ Perm Buffer Set (Cat. No. 425401) and intracellularly stained with Alexa Fluor® 488 anti-PTEN Phospho (Ser380) (clone A22005D) or Alexa Fluor® 488 mouse IgG1, κ isotype control (open histogram, dashed line) (representative histogram for either untreated or treated cells) (Cat. No. 400133).

    IHC staining with Alexa Fluor® 488 anti-PTEN Phospho (Ser380) was performed on formalin-fixed paraffin-embedded human colon adenocarcinoma tissue following antigen retrieval with Citrate buffer (Cat. No. 420902). The tissue sections were incubated with Alexa Fluor® 488 mouse IgG1, κ isotype control (panel A) or with Alexa Fluor® 488 anti-PTEN Phospho (Ser380) (clone A22005D) (panel B). Nuclei were counterstained with DAPI (Cat. No. 422801) (overlay in panels A and C). Scale Bar: 50 µm

Description

PTEN is a tumor suppressor gene which encodes a phosphatase that preferentially dephosphorylates phosphoinositide substrates and thereby modulates cell cycle progression and cell survival. PTEN is an important negative regulator of the PI3K/AKT/mTOR signaling pathway by dephosphorylating PIP3. PTEN is commonly mutated in human cancer, hence, loss of expression/function of PTEN due to mutations have been observed in prostate cancer, glioblastoma, endometrial, lung and breast cancers. Other non-cancerous clinical disorders associated with PTEN mutation are Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, and proteus-like syndrome. PTEN is phosphorylated at several residues and some lead to increase in activity while others lead to loss of function and degradation. Specifically, phosphorylation at serine 380 residue by casein kinase 2 (CK2), leads to degradation of PTEN in the proteasome.

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µL volume. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 1.0 - 10.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.

Application Notes

We recommend using True-Phos ™ Perm Buffer (Cat. No. 425401) for fixation/permeabilization for use in intracellular staining for flow cytometry (ICFC).

For use in immunohistochemistry on FFPE tissues (IHC-P), either Tris-EDTA pH 9.0 Buffer (Cat. No. 422703) or Citrate buffer (Cat. No. 420902) can be used for antigen retrieval.

Antigen Details

Structure
PTEN is a 403 amino acid protein with a predicted molecular weight of 55 kD. It has a tyrosine phosphatase domain and a C2 domain
Distribution

Cytoplasmic (Inner cellular membrane) and nuclear

Function
PTEN functions as a lipid and protein phosphatase. It is negatively regulated by phosphorylation at the C-terminal domain which leads to proteasomal degradation.
