The problem with our Ft4 kits is down to the magnetic particles, some of
which will either not resuspend no matter how long or hard they are mixed,
or else a clump resuspends which cannot be broken up. This occurrence is
random in the sense that one or more 50 test packs within a 5 pack kit may
be affected and yet the kit may also include a pack which will suspend as
normal. We are told that this is possibly a transport problem. I would ask
other FT4 kit users to look at their kits and check whether all the packs
suspend correctly. This problem now appears to be present in a variety of
lot numbers.
Please let me know, even if you do not have the problem.
