I have been injecting Xenopus oocytes with a commercial restriction
enzyme. Apparently, some component of the enzyme's storage buffer is
toxic to the oocytes (I think it's the glycerol). Does anyone know of a
good way to exchange the storage buffer with one that might be less
toxic? No, the company won't do it for me. The real killer here is that
I only want to clean up a small amount of enzyme (which is about 27 kD),
so methods such as dialysis may be problematic in that they might leave
the enzyme in a large volume.
