Two of the proteins I am researching are known to interact. However, I would like to know if they interact with other proteins as well, and possibly form a pathway. Which analytical technique(s) I should use to determine this if I did all in silico analysis already? Any suggestion is welcome.

I am using a nematode C. elegans in my research, and RNAi is not an option, as I have already performed it.

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once.

  • $\begingroup$ This question is far too broad. From the help center: Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much. The field of protein-protein interactions is quite wide, and there are numerous techniques to consider. This is not the place to list all of them. $\endgroup$ – MattDMo Jan 14 '17 at 19:54

There are plenty of methods to use. Here is a overview and background of some common methods as written by ThermoFisher:


There is also phage display if you want to find binding partners, which is a very interesting method to narrow down binding partners from an entire interactome. It simple to set up in a lab and you can perform it all in a 96-well plate using ELISA and several rounds of phage selection. And of course there are also e.g. yeast-2-hybrid (Y2H) or co-immunoprecipitation (Co-IP).
