CDNA SIZE FRAC COLUMNS 3 COLUMNS，18092015，Invitrogen

cDNA Size Fractionation Columns offer an efficient and convenient method for size-fractioning double-stranded cDNA (1).

• Pre-packed, disposable columns efficiently remove small (<500 bp) cDNAs-including residual adapters, linkers, or other fragments that could interfere with ligation of cDNA to the vector
• Columns size-fractionate cDNA >500 bp

Performance and Quality Testing: Wash time, drop volume during elution of fragments, and the ability to clearly and cleanly separate a mixture of dyes, including xylene cyanol and bromophenol blue, are evaluated.
