How do you find out what CD markers are on a cell?

How do you find out what CD markers are on a cell? You would think that there's nothing you can do nowadays that has never been done before, right? But that's not the case. That's not true. So there are databases that will tell you this and that is expressed on a certain cell type. But if you want to make certain that that's actually the case and if you have an idea for a certain type of treatment, then I would strongly advise to go back to the original data and perform your own analysis and confirm that that's actually the case or not the case. And that's how we've done it in the past. So we've come up with a hypothesis and we said this could be a good target and then we went back and analyzed and performed a lot of analysis and just basically confirmed what the exact picture looked like. So there are data, but they're not always completely reliable.
