If you wanted to test a peptide you designed, you can do a [phage display][1] or a [yeast display][2] experiment to assess binding affinity. What are the trade-offs between these two methods? I've heard anecdotally that yeast display is more sensitive and closer to human cells? [1]: https://en.wikipedia.org/wiki/Phage_display [2]: https://en.wikipedia.org/wiki/Yeast_display
