  • Relevance
    Phosphatidylinositol 4,5-biphosphate (PIP2) is a membrane phospholipid that has been implicated in a variety of cellular processes, including synaptic vesicle recycling and signal transduction pathways. PLCD4 hydrolyzes PIP2 to generate 2 second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3).


  • ICC/IF image of ab11039 stained human HepG2 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab11039, 5 µg/ml) overnight at +4°C.

    The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgM (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in HeLa, Hek293 and MCF7 cells.

  • IHC image of PIP2 staining in mouse normal brain formalin fixed paraffin embedded tissue section. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30mins. The section was incubated with ab11039, 1µg/ml overnight at +4°C. An HRP-conjugated secondary (Ab98679, 1/1000 dilution) was used for 1hr at room temperature. The section was counterstained with haematoxylin and mounted with DPX.

  • Immunofluorescence analysis of Human SaOS-2 (Human osteosarcoma) cells, staining PIP2 with ab11039. Cells were either unstimulated (upper panel) or stimulated with direct current (lower panel).

    Cells were fixed in formaldehyde, permeabilized and then blocked with 1% BSA for 20 min. Cells were then incubated with a primary antibody (1/200) overnight at 4°C. A FITC-conjugated anti-mouse IgG was used as the secondary antibody.
  • IHC image of PIP2 staining in a formalin fixed, paraffin embedded human normal kidney tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab11039, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.


    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for contacting us.

I personally don't have experience with using a freeze-thaw permeabilization, but from doing a quick literature search it does seem to be a good method for staining intracellular membrane proteins.

Thank you very much for your reply.
Since PIP2 seems to be ubiquitously expressed, I would expect most, if not all, cells to be positive controls. For ab11039, HepG2 may be the best positive control since the antibody has been tested in this cell ...

Thank you again for your reply and for your patience.
I have followed-up with the lab and the secondary antibody mentioned in the image caption was actually an anti-mouse IgM, not IgG. We have corrected this in the caption. Thank you very much for...

Thank you very much for your reply.
I'll need to check with the lab to confirm the type of secondary antibody that was used in this ICC/IF protocol. The anti-mouse IgG secondary antibody described in the image caption would still probably cross-re...
