Modification by group: Modified backbone
Position of modification: internal
Phosphorothioates contain the exchange of one oxygen in the phosphate bond with sulfur. By exchanging oxygen for sulfur, the resistance of the oligonucleotide to nucleases increases.
pure phosphorothioates: substitution is made in all phosphate linkages in the chain
mixed phosphorothioates: substitution is only made on selected phosphate bonds.
Phosphorothioates are used for antisense applications where a 10 μmol scale is usually selected.

General Terms and Conditions
gb Easy PCR Master Mix gb Easy PCR Master Mix consists of hot-start Taq DNA polymerase, reaction buffer, dNTP and MgCl2. The Taq polymerase is chemically modified DNA polymerase from Thermus aquaticus. This polymerase is completely inactive at room temperature but it is rapidly activated during the initial denaturation step of PCR. The product falls into a group of TaqMan Real-Time PCR Master Mixes to provide probe-based qPCR.
Why choose alternative dyes instead of "genuine" dyes? First, they are cheaper, and second, they can give the same results. Another reason is that the number of suppliers who can provide modified oligonucleotides is restricted - only a patent or a licence owner is usually allowed to produce them.
