Are you using GeneClean or something similar? I've noticed that some
glass fines often come along with the eluate, then they settle out
after strorage (or you could spin them out). They would likely inhibit
other enzymatic steps, if present.

Alternatively, you could switch to a purification kit that has the
silica in a solid support.
