Hello everyone,

Please allow me to kill two off-topic birds with one email ‘stone’:  

1) Can anyone suggest where I can lay hands on the pREP4-GroESL plasmid for 
bacterial co-expression of GroEL and GroES? I’ve checked with the original 
author (Philip Cole), but it’s been decades since he published on this, and 
he’s not sure he can find the plasmid. However, I see recurrent (and recent) 
references to the plasmid in the literature, so I guess that it’s loose in the 
wild…

2) We’re looking for a contract research organization to do some Bac-Mam 
expression for us (we’re in a hurry to get some results, so we’d like to farm 
it out rather than get the technology going in-house). Can anyone recommend a 
group (ideally in the US, for logistical ease)?

Thanks for any help.

Cheers,

Pat
