Dear Scott and the board, Sorry for the email not intended for all. This is a really useful protocol for S2s; we so use slightly different ways of making protein in S2. My students will takes notice of this! Best, Engin On 12/23/16 5:56 AM, Engin Özkan wrote: Hi guys, Here is a protocol

Hi guys, Here is a protocol about use of S2s and SeMet labeling from the ccp4bb (the crystallographers' friendly bulletin board for knowledge exchange). I suggest you read the thread starting from the bottom to follow the logic. There will be useful information there. Best, Engin On 12/23

Nothing specific about S2 cells to contribute... However, S2s usually grow fine in other insect media, such as those intended for lepidopteran cell lines like the Sf9 and High Five. Protocols established for those cell lines, for example, check out those using the medium ESF-921, would probably

[ccp4bb] Why TLS refinement may go wrong and why it is so often the case (was: Re: [ccp4bb] Calculation of generalised R-factor?)

2016-12-22 Thread Pavel Afonine
Dear Ethan, thanks for comments. I do remember we talked about it last year in Argonne at CCP4 school and we did not seem to agree indeed. Let me bring my arguments as you stated yours. Refinement is an optimization problem that involves model, data and fitting tools (such as target function and

Hi All, Brings back a lot of memories about what can go wrong - some of them lessons hard learned transporting crystals in collaboration with Gloria! I’d echo Gloria’s advice and go further recommending the Hampton Research capillary cutter, Tygon tubing that fits the end of the capillary, a s

I would recommend just mounting them in capillaries without loops, as this will travel better. Put slugs of mother liquor on either side, seal with wax and then coat wax and onto the end of capillary glass lightly with fingernail polish. We have had terrible luck with FedEx delivering damaged crys
