Our Abpromise guarantee covers the use of ab95230 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 53 kDa (predicted molecular weight: 57 kDa).

  • Anti-Angiopoietin 1 antibody (ab95230) at 1 µg/ml + E10 Mouse Embryo Brain Tissue Lysate at 10 µg

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 57 kDa
    Observed band size : 53 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 95 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 20 minutes
    The band observed at 53 kDa could potentially be a cleaved form of Angiopoietin 1 due to the presence of a 19 amino acid signal peptide. Abcam recommends using milk as the blocking agent. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
  • ICC/IF image of ab95230 stained MEF1 cells. The cells were 4% formaldehyde 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 (ab95230, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 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) at a concentration of 1.43µM.

Thank you for contacting us.

I have attached the results of the sequence alignment between mouse and human angiopoietin 1.

The link to our IHC-P protocol is as follows:

Thanks again for the additional data. I think there are a few confounding factors here that make the western blot data difficult to interpret confidentally: 1. I agree with you that the intense 40kDa band is likelyb-actin in both blots, but we can not ...

Thanks for the additional information. A couple more questions... 1. Are one or more of the samples from the blot considered a negative control, in that it is known to not express Angiopoietin 1? 2. After stripping but before reprobing, was it determin...

Thanks for providing the western blot images as well as the protocol and sample preparation details. I just have a few additional questions: 1. Was any other antibody usedsuccessfully in western blotting with these same samples? 2. How much protein was...
