cDNA size selection columns

[Bruno Cenni]

Hi all,

I want to remove dNTPs and adaptors from a cDNA-pool/library for its
subsequent cloning into a vector. I don't really want to select for large
cDNAs, but simply efficiently remove the other "small" stuff. I know of the
CL-4B protocol in Maniatis, but would like to use premade columns. Does
anyone know which to use or rather not to?

TIA

Bruno
