HIGHLIGHTS
Porous silica with 25 nm (250 A) pore size
C18 bonded phase in TSKgel OligoDNA RP suited for
Oligonucleotides
C1 bonded phase in TSKgel TMS-250 suited for proteins
TSKgel TMS-250 is exhaustively and repeatedly reacted with trimethyl
silyl groups. Standard nomenclature designates the bonded phase as
C1. This wide-pore column is recommended for the analysis of proteins.
TSKgel OligoDNA RP contains a monomeric C18 bonded phase that
is not endcapped and has a relatively low carbon content of 10%.
It is ideal for the purification and analysis of oligonucleotides (up to
500-mer), RNAs, and DNA fragments. It possesses high-resolving
power for octamers of similar sequence.
Applications
TSKgel TMS-250
TSKgel TMS-250 is ideal for the separation of proteins which
exhibit sharp peaks relative to wide-pore C8 or C18 columns. It can
accommodate even large proteins, such as aldolase (158 kDa). The
resolution of proteins on TSKgel TMS-250 columns is shown in Figure 3.
TSKgel OligoDNA RP
The semi-preparative isolation of a 49-mer oligonucleotide from the
crude synthetic reaction mixture using a 7.8 mm ID TSKgel OligoDNA-RP
column is shown in Figure 4. The purity of the isolated oligonucleotide
was subsequently verified on an analytical 4.6 mm ID TSKgel OligoDNA-
RP column.
