Dear all, Could anyone tell me your experience with Biacore (any models) or a similar SPR-based technology for measuring interaction kinetics? I also want to know the price ranges to discuss with our department/facility managers. Thanks, Gang

Re: [ccp4bb] Maltose binding protein as a tag

2013-07-24 Thread Gang Dong
Dear Kostas, MBP by itself is a monomer. In most of our cases using it as a fusion tag, the yield of a target protein increases drastically (i.e. 5 to 20 folds more). However, we have seen in a couple of cases that the target proteins strongly interact with the MBP tag, which causes
