No kidding. That means the procedure worked perfectly ;-)

Seriously, those pellets are very difficult to to resuspend. I use a
probe-type sonicator and sonicate about three or four times between
incubating the samples at 50C for an hour or two between sonications.
Basically, assume it takes all day, and plan to have something else
going on at the same time to keep yourself busy.
