Thanks for the reply. actually we do not use any lysis buffer just suspend
our e.coli cells in water and perform sonication thereafter we centrifuge at
140000 rpm to collect the inclusion bodies and these are contaminated with
host cell proteins too.

as mentioned by artem, i just wanted to know if we centrifuge at 5000 - 6000
rpm then will the cell debris not settle down. kindly guide.

as such i shall try the method and revert back. thanks for the reply
