  • Function
    Probably involved in connections of major cytoskeletal structures to the plasma membrane. In epithelial cells, required for the formation of microvilli and membrane ruffles on the apical pole. Along with PLEKHG6, required for normal macropinocytosis.
  • Tissue specificity
    Expressed in cerebral cortex, basal ganglia, hippocampus, hypophysis, and optic nerve. Weakly expressed in brain stem and diencephalon. Stronger expression was detected in gray matter of frontal lobe compared to white matter (at protein level). Component of the microvilli of intestinal epithelial cells. Preferentially expressed in astrocytes of hippocampus, frontal cortex, thalamus, parahippocampal cortex, amygdala, insula, and corpus callosum. Not detected in neurons in most tissues studied.
  • Sequence similarities
    Contains 1 FERM domain.
  • Developmental stage
    Very strong staining is detected in the Purkinje cell layer and in part of the molecular layer of the infant brain compared to adult brain.
  • Post-translational
    Phosphorylated by tyrosine-protein kinases.
  • Cellular localization
    Apical cell membrane. Cell projection. Cell projection > microvillus membrane. Cell projection > ruffle membrane. Cytoplasm > cell cortex. Cytoplasm > cytoskeleton. Localization to the apical membrane of parietal cells depends on the interaction with MPP5. Localizes to cell extensions and peripheral processes of astrocytes (By similarity). Microvillar peripheral membrane protein.

  • All lanes : Anti-Ezrin antibody [3C12] (ab4069) at 1 µg/ml

    Lane 1 : Wild-type HAP1 whole cell lysate
    Lane 2 : EZR (Ezrin) knockout HAP1 whole cell lysate
    Lane 3 : HeLa whole cell lysate
    Lane 4 : MEF whole cell lysate

    Lanes 1 - 5: Merged signal (red and green). Green - ab4069 observed at 81 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab4069 was shown to specifically react with Ezrin in wild-type HAP1 cells as signal was lost in EZR (Ezrin) knockout cells. Wild-type and EZR (Ezrin) knockout samples were subjected to SDS-PAGE. Ab4069 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at 1 μg/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

  • Overlay histogram showing SH-SY5Y cells stained with ab4069 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab4069, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in SH-SY5Y cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Thank you for your enquiry. I am pleased to help answer your questions:

1. Any IHC-P testing images we have will be available on the individual online datasheets. Please let me know if there is not one available for the antibody you are interested in, and I can try to obtain this for you.

2. We have one Ezrin antibody tested in IHC-P and human samples which is prediluted:

ab18057 Mouse monoclonal Ezrin antibody [SPM244], prediluted
Tested in: IHC-P
Reacts with: Human, Monkey
https://www.abcam.com/index.html?datasheet=18057 (or use the following: https://www.abcam.com/index.html?datasheet=18057).

3. I am sorry to confirm that ab18057is not in stock at the moment, but stock will be available within to send out 1 - 2 weeksafter your order. however, please note that as you are in India, delivery after this could take more time. I can suggest to contact one of our Indian distributors for more information (please see below).

4. The recommended dilution for IHC-P is usually provided on the individual online datasheet: However, please note that this is a recommendation only and may require some individual optimization.

5. I can confirm that ab4049 is not provided in prediluted form. If an antibody is prediluted, this will be stated.

The online datasheet for ab4049 recommends to dilute at 1:50 - 1:100 for IHC-P.

6. This will depend on which particular antibody you choose, what optimized dilution of antibody you use, and how much you put on each slide.

7. As you are contacting us from India, I can suggest to contact one of our Indian distributors who will be able to provide a price for you. They will also be able to provide an estimate on how long it will take for an item to ship to you.
