Dear Gloria, I think that the most economical biotinylation manner is in vivo, by co-expression of a tagged protein with BirA. One can PCR amplify the BirA cDNA from E. coli and clone it into plasmids for any expression system and sub-cellular localization needed. Ready to use BirA expression

[ccp4bb] E. coli BirA biotin ligase expression/purification

2019-10-21 Thread Gloria Borgstahl
Dear friends in crystallography, I know this seems unrelated, but it really isn't ... please forgive me. We are trying to use the Avitag/BirA system to specifically biotinylate target proteins in an economical manner. Are any of you purifying the BirA enzyme in your lab for biotinylation and if

Re: [ccp4bb] off topic: microscope in glove box

2019-10-21 Thread Artem Evdokimov
Short version: It should be OK, especially since the vacuum is transient and not particularly 'strong*' :) Long version: if this is an older microscope there may be further delamination of optically bonded components if air is already admitted between glass planes (i.e. the optical cement is worn

Dear all, I want to put one of our microscopes into the glove box. Does anybody know whether some parts of the microscope optics do not like vacuum in the air lock ? Thanks and best regards, Guenter To unsubscribe
