Hi Jason, Thanks a lot for the information. I would very much like to attend one of your courses, if you guys are having one in Europe. We plan on doing some protein sequencing in our lab in the next few months, so I'm sure the course will be worth it.
Thanks again for your time, Panos On Tuesday, 5 June 2018 19:08:20 UTC+3, Jason Winget wrote: > > Hi Panos, > From your questions it seems like you would get a lot of benefit from the > TPP 5-day course.
