Hi all, I apologize to all of you for my previous blank posting at CCP4BB; It happened accidently. I would appreciate your comments on oxidation of selenomethinone in stored pellet 1.How long one can store Seleno-met expressed protein in bacterial pellet at -80 degree C without significant

Re: [ccp4bb] About seeding in microbatch under oil crystallization

Hi Donghui, I tried the microseeding using Hampton seeding tool (http://hamptonresearch.com/product_detail.aspx?cid=18sid=157pid=448)  for under oil microbatch (without caring about wiping out seed by oil). It is possible to seed the microbatch drop this way. cheers, ravi Ravindra D. Makde
