Example: One oligo of 20 bases at the 200 nmol scale, of which 3 backbone bonds (links) at each end are phosphorothioated:  20 x 0.39 = 7.80, plus (3+3) x 1.50 = 9.00, for the total of 16.80.  Please use asterisks to describe the phosphorothioated backbone bonds (links), for example A*T*C*AGTGACTCGTAGTG*C*T*A
