  • Function

    Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance, neuronal growth cone collapse and cell migration.
  • Tissue specificity

  • Sequence similarities

    Belongs to the DHOase family. Hydantoinase/dihydropyrimidinase subfamily.
  • Post-translational

    3F4, a monoclonal antibody which strongly stains neurofibrillary tangles in Alzheimer disease brains, specifically labels DPYSL2 when phosphorylated on Ser-518, Ser-522 and Thr-509.

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.

If there are many bands on the Western blot, I generally recommend the try to optimize the following steps

I can strongly recommend to test different blocking buffers. Blocking with milk or blocking with BSA can provide very different results (see for example the image on the datasheet of ab9385). If BSA has been used for example as blocking, I would suggest to test also milk blocking.
I can recommend also to maybe dilute the primary antibody further. High antibody concentration can lead to unsprecific staining.
It is also important to know whether the background is might coming from the secondary antibody. This can be checked by performing a “no primary” control, where the Western blot procedure is exactly the same.
In order to be sure that the protein is not in a complex or degraded, I can recommend to use denatured and reduced conditions (by heating the samples prior loading in SDS with DTT or bME) and to prepare the cell lysates freshly and with proteinase inhibitors.
Lastly, maybe the washing steps can be increased.

We are not aware of any specific issues with this antibody. I have therefore provided general tips. Please provide me however also with the protocol you have performed, so I can see whether there is any step for which I could make additional suggestions. To do so, I am attaching our questionnaire which will help you to put the information regarding the samples tested and the protocol used together. Once we receive the completed questionnaire, I will look at the protocol and see if there is any additional 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.
