PHYSICAL DATA

The physical data table contains information which is unique to each monomer phosphoramidite. The molecular weight (MW) is the formula weight of the fully-protected monomer phosphoramidite. The MW is used to calculate the volume of solvent required to dilute 0.25g of the monomer to give a final 0.1M concentration. This figure is also shown in the table. The unit molecular weight (Unit FW) is the formula weight of each monomer once inserted into an oligonucleotide with all protecting groups removed. To obtain the molecular weight of a specific oligonucleotide, the following formula is used:

Oligonucleotide MW = Sum of Unit FW - 61.96
