: "The resin used in Magic Minipreps is a Celite slurry suspended in 7M Guanidine
: Hydrochloride-1M KOAc buffer, pH 5.5.....Note: ( Promega recently modified
: their original Celite resin -- or Magic miniprep resin and are currently
: selling a derivatized Celite under the name of Wizard....)"

: This information comes from an internet posting, although I received it from a
: graduate student in the lab in which I work. Also outlined in the report is 
: several plasmid prep protocols using diatomaceous earth (celite) resin in the 
: purification. I can't find a source of the report, but I'm sure it is still
: posted out there somewhere on the net.

: Let me know if you're interested...I will try to dig up the original posting.
