Hi, I'm an undergraduate student currently learning biochemistry. I have seen a gel filtration simulation and a peptid sequence analysis simulator for PC. Does anyknown know where to find such simulators for mac? Best wishes / Tobias L Tobias Lehtipalo, b94tle at student.tdb.uu.se Adress: Sturegatan 23B 1tr, 75314 Uppsala; Tel. 018/50 39 78
