Keeps cropping up this one; a photocopy just arrived in our lab called "an
inexpensive alternative to Glassmilk for DNA purification", it's Trends In
Genetics 11:pg 8, the technical tips section. Apparently you use silica from
Sigma (S-5631), wash it in PBS and resuspend in NaI. Anyway it's all there.
They also describe a wash buffer which is presumably similar to NewWash, that
other old chestnut: 50mM NaCl, 10mM Tris HCl pH7.5, 2.5mM EDTA, 50% v/v
