Yes, the hinge region between Fab and Fc is highly flexible. If you look at IgG by EM you will see many different conformations. Best to use Fab or scFv. Jarrod Mousa On Thu, Jun 22, 2017 at 1:39 PM, Cheng Zhang <chengzh1...@gmail.com> wrote: > Hi all, > > I have a naive

[ccp4bb] Lipid molecule

2015-04-24 Thread Jarrod Mousa
Hi all, Picture attached. I solved the structure of a membrane protein using LCP. When trying to identify the cation-binding site, I co-crystallized with Rb+. I see strong density corresponding to Rb+, and it was confirmed in an isomorphous difference map. One problem: in the native structure I

[ccp4bb] Best screens for Fabs and antibody-antigen complexes

2015-04-15 Thread Jarrod Mousa
Hi all, A little off-topic: I am beginning a post-doc in a non-crystallography lab in a month, and I am working to get a list together of screens to purchase before I arrive. Can anyone recommend screens for crystallizing antibodies (Fab fragments), and Fab-antigen complexes? Thanks, -Jarrod

[ccp4bb] RfreeRwork

2015-01-24 Thread Jarrod Mousa
Hi all, I am wondering what the conditions are when Rfree is less than Rwork. I have seen this when trying certain models to solve my structure, but I am not sure why this occurs, or if this is valid or not. Thanks, Jarrod Mousa U. of Florida

had luck using a 100 uL teflon ferrule (you have to hollow it out a bit) for this purpose. We have a machine shop here that can do the ferrule removal. I didn't have much luck doing this on my own. Hope that helps, Jarrod Mousa Graduate Research Assistant University of Florida -Jarrod Mousa On Mon

[ccp4bb] Merging Data from Multiple Crystals

2014-03-27 Thread Jarrod Mousa
Hi, I am trying to solve the structure of a membrane protein. The protein has 12 helices and I have a good molecular replacement model that seems to work for about half of the structure. I used chainsaw to convert the amino acid residues to that of my protein sequence, and the density fits the

[ccp4bb] Merging Data from Multiple Crystals

2014-03-27 Thread Jarrod Mousa
I am also trying to merge data from multiple crystals that I collected from. I have tried to reindex the data in CCP4 after indexing in iimosflm, and then put these .mtz files through sortmtz before scala, but I keep getting an error in sort mtz: From ccp4_lwbat: warning: attempt to add new

[ccp4bb] cTruncate problem

2014-03-27 Thread Jarrod Mousa
I can index my data through imosflm with no problems, but when I try to scale using aimless, the program will not run if I also run truncate (or old truncate). Here is the error message I get below. Could anyone elaborate on what this means? Thanks. P.S. I can take the scaled .mtz file from
