Liposomes (prepared in PBS with lipid A, phosphatidylcholine (PC) and cholesterol) containing synthetic di-palmitoyl PtdIns(4,5)P2.
This antibody clone is manufactured by Abcam.
For testing in lipid dot blot assay, follow the protocol used in Thomas et al. Biochem Soc Trans 27:648-52 (1999) (PMID: 10917659, please see the References tab).
Our Abpromise guarantee covers the use of ab11039 in the following tested applications.
|IHC-P||Use a concentration of 1 - 5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
|ICC/IF||Use a concentration of 1 - 5 µg/ml.|
|ELISA||Use at an assay dependent concentration.|
|Neutralising||Use at an assay dependent concentration.|
|IP||Use at an assay dependent concentration.|
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.
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.
