[ccp4bb] Isothermal titration calorimetry

2013-03-23 Thread Sameh Soror
Dear All, I am sorry for the off topic question. I am going to buy ITC to study protein-protein protein-ligand interactions I am comparing microcal, GE and nanoITC, TA instrument.. any suggestions, recommendations, good experiences or bad experiences. is there a better system. Thank in

I would recommend the Microcal ITC 200, hands down. Not only is it an amazing instrument with the optional automated sample loader (which is worth every penny), but we were able to do experiments (multiple) using FULL-LENGTH p53 binding to a weak cognate protein. I believe this was the first

It might be worth to consider the question more in detail. Do you want to study thermodynamics of the interaction, or a KD would do? If the former, you need ITC. If the latter, and you want to study things at the level of KD only, maybe investing on a plate reader, thermophoresis, or some

Dear colleagues, We are planning to replace our crystallisation hotel, a CrystalPro system that has already done its job. We are undecided about what new system to choose and would much appreciate hearing your experiences with your own systems. We are looking for a unit with a capacity of

George, would you please explain your comments? We've found the TA Instruments analysis software very robust and user friendly. We have the low volume nanoITC from TA instruments and get equivalent #'s in our comparison tests to the Microcal instrument. Cheers, Chris -- Christopher L.
