Target

  • Function

    Ligand for members of the frizzled family of seven transmembrane receptors. Probable developmental protein. May be a signaling molecule which affects the development of discrete regions of tissues. Is likely to signal over only few cell diameters.

  • Tissue specificity

    Expressed in brain in the thalamus, in fetal and adult lung and in placenta.

  • Sequence similarities

    Belongs to the Wnt family.

  • Cellular localization

    Secreted > extracellular space > extracellular matrix.
  • Information by UniProt

  • Database links

    • Form

      The WNT gene family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis.

    Question

    Thanks for getting back in touch.
    I compared muscle stem cells from two metabolically distinct muscles – I found that these populations stained differently for Wnt2, with one population having more intense nuclear staining that the other. I have attached images for you to see the difference. In the image with the darkest staining (nuclear), you can see that there are also cells which are negative for the stain, which suggests that it not therefore indiscriminately staining all nuclei. There is some light staining of the cytoplasm also for both populations which I don’t know if this is as expected or due to too high Ab conc.

    OK. I use the Vecta stain Elite ABC kit
    - Grow cells as monolayer and fix in 70% ethanol, wash 2x pbs, 1x water, store in water until staining

    - Block in 1% normal horse serum 30 mins

    - Remove NHS and add primary antibody – Wnt2 (AB109222) 1/200 dilution in PBS (range on data sheet 1/100- 1/250)

    - Inc 1 h at room Temp on rocker

    - Wash 3x pbs

    - Add secondary antibody – biotinylated anti-rabbit (1%), inc as before.

    - Wash cells 3x pbs

    - Add 1% A+B reagent as Vecta protocol states for 30 min

    - Was cells 4x pbs

    - Add substrate – peroxidase (VIP substrate kit) ˜5 mins

    - Wash 3x pbs

    - Wash 1x water, store in water.

    - done

    I look forward to your comments.

    Kind regards

    Answer

    Thank you very much for providing the images and protocol info.

    I have checked different publications and databases; all show cytoplasmic staining. The links to the few are attached below;

    http://www.nature.com/cgt/journal/v16/n4/full/cgt200878a.html

    The following Abcam antibody also show cytoplasmic staining

    https://www.abcam.com/WNT2-antibody-ab27794.html#WNT2-Primary-antibodies-ab27794-3.jpg

    I would suggest tweaking a protocol and then checking if the result improve

    - Fix cell in acetone for 10 minutes, or 4% icecold PFA or icecold methanol
    - Use 5 - 10% NHS for blocking (1hour)
    - Try the normal ICC/IF procedure using fluorescent secondary antibody
    - Use PBST (0.1% Tween) instead of PBS
    -Try no primary control also

    The other question I have is
    - Have you stained nucleus by any DNA dye?

    I hope the results will improve after following these suggestions. Please let me know if you have any feedback or would like to discuss this further.

    Answer

    Thank you for contacting us.

    I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

    I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody.

    I look forward to receiving your reply.

    PS: Please either fill in the attached questionnaire or attach the protocol you have been using.

    Question

    What is epitope site of this antibody, even the general region would be helpful? Also do you know if this antibody will react with other WNT family members?

    Answer

    Thank you for contacting Abcam. The peptide maps between amino acids ********* of human Wnt2 (UniProt:  P09544). We have not yet tested whether this antibody will react with other WNT family members, but I did Blast the immunogen sequence and it did not pull out any other Wnt family members. If there is anything else I can help you with, please let me kno
