Need fast mini-prep protocols

[Andreas Ruppert]

To screen large numbers of E. coli colonies, we employ microtiter filter 
plates and a suction chamber from Eppendorf for mini-preping according to the 
alkaline lysis method. By replacing any centrifugation step by filtration we 
can handle up to 96 colonies in parallel. For restriction analysis we pool 
up to 5 DNAs. To split the pool, no further mini-preping is necessary, we just 
repeat the digestion with the separate DNAs (Anal. Biochem. 230, 130-134, 1995)
