Now I am looking for some software to test primers with. I always used to eye-ball a sequence, and based on that pick some good looking sequences, put it into the Mac program: Amplify. This program then visualizes how specific and efficient the priming is on the target sequence by virtual pcr products. BUT changed workplace, no Amplify.. I am trying to find it on the net though. Does anyone now other programs which can handle the task? PC or Mac operatable? I know of primer3 from MIT, but I don't like it..
