How to solublize bacterial membrane

[Alex Chang]

I am working with a recombinant protein which is expressed in the 
periplasmic compartment of E. coli. Somehow, most of the expressed and 
secreted protein is stuck with the bacterial membrane. So, I need to 
solublized the membrane in order to isolate the recombinant protein.

I'd like to know if there are any detergent which can solublized the
bacterial membrane, in the same time does not do much harm to the rProtein
(I don't want to use guanidium HCl, for example). Will Triton X-100 do the
job?
