EMD Millipore 42412 Centrifugal Filter Units, 100k NMWL, 24/pk, blue

Ideal for dilute (ng/mL to µg/mL range) protein solutions. Low-binding ultracel-YM regenerated cellulose membrane available with different molecular weight cut-offs. Used in standard 1.5 mL tube fixed-angle rotors. Applications include concentrating and purifying proteins, antibodies and nucleic acids (alternative to EtOH precipitation), desalting and buffer exchange, and removal of primers, linkers and unin-corporated label.
