TSKgel OligoDNA-RP
TSKgel OligoDNA-RP is specifically designed for the purification of oligonucleotides, and RNA and DNA fragments (up to 500-mer). TSKgel OligoDNA-RP columns can provide excellent separations of samples with very similar sequences. The packing is prepared by monomeric binding of octadecyl silyl groups to 5 μm spherical silica gel with 25 nm (250 Å) pores. This packing is not endcapped and it has a relatively low carbon content of 10%.
