Glasgow Caledonian University runs a week long molecular biology course (In Glasgow Scotland)

If you are interested I think the best person to contact would be Dr. Adrian Pierroti email: A.Pierotti@gcal.ac.uk
I don't know what the cost is but they take in quite a few industry and hospital staff to train up in molecular biology techniques as well as providing a similar course for all their undergrads and grad students.
I don't know what other unis do them - but I've done this course and its good if you want the basic principals and hands on experience.
They tend to run this course during the summer vacation period I think
Hope this helps
