Sorry did not mean to go off topic. Original question was requests for suggestions of cleavable c-term tag vectors. I only meant to provide info on one type recommended by another. Others may have further suggestions for Flavio. From: CCP4 bulletin board on behalf of Karla J. F. Satchell Date

Hi Gerard, indeed, thank you for your clarification, I'm rusty since I'm on something else now. Anisotropy might not be the right word, as it does mean the opposite of isotropy. I meant 2 phenomenon at play: lack of completeness in the high resolution shells, and different intensity falloff

Hi everyone— Thought I might chime in. This technology was developed in my lab based on our studies of toxins and we have methods papers and two patent. The CPD-tag works great for production of protein with minimal residual residues on the protein. Our studies indicate that it can help solubil

Hi Flavio While i am not aware of any commercial vector with cleavable c terminal tag, you can easily make your own by introducing protease cleavage site of your choice. However this strategy will results in quite a few extra residues from protease site. An alternative, which is

Dear Vincent, Thank you for chipping in as you did, with so much useful feedback about the difficulty of re-using PDB depositions containing anisotropic data. It is a very useful picture of what is definitely a "bleeding edge" on the "R" side of the wwPDB's "FAIR" ideal. It would be mos

Hi Clemens and all, I've been following with a lot of interest of course, anisotropy has taken a lot of space in my membrane-protein crystallography life. I remember the many exchanges we've had with you and Global Phasing, as well as many other software developpers over the years. I would li
