MODIFIER PRICING

There are three factors in determining the cost of a modified oligo:

 

The Synthesis Cycle to be Used:

Determining the cost of a modified oligo begins with selecting the scale of the synthesis and then calculating the setup charge and the per- residue charge for that scale. A normal DNA setup charge is used unless there is an RNA or 2'-O-methyl RNA residue at the 3' end for which those setup charges would apply. A normal DNA per-residue charge is used for the modified residues unless those modifiers are RNA or 2'-O- methyl RNA. Please see our price schedule and Oligo Cost Calculator for normal setup and per-residue charges.

Most of our specialy reagents are ordered from Glen Research. Glen offers only 0.2 micromole and 1.0 micromole columns for initiating syntheses with 3' modified residues (40 nanomole columns are not available). Therefore, the Normal 0.2 µm and Normal 1.0 µm synthesis cycles are used for all syntheses with modified 3' residues.

The LV (low volume) 40 nm, LV 0.2 µm, or Normal 1.0 µm cycles are used for all syntheses with unmodified 3' DNA residues. The LV cycles use approximately 70% less reagent than the Normal 0.2 µm synthesis cycle.

The Wide Pore 1.0 µm cycle is used for all 1.0 µm oligos over 50 bases in length.

Phosphorothioate linkages will be charged at $5.75 per linkage ($6.61 for non-Yale orders) to cover additional labor in setting up and maintaining the synthesizer.

 

The Number of Additions per Bottle:

Glen generally offers specialty reagents in 50 micromole, 100 micromole, and 0.25 gram bottles.

The number of additions available per bottle varies with each cycle and is displayed below:

50 micromole bottle

LV 40 nm cycle:

7 additions

LV 0.2 µm cycle:

5 additions

Normal 0.2 µm cycle:

2 additions

Normal 1.0 µm cycle:

0.25 g Bottle

The number of additions per 0.25 g bottle varies with molecular weight. E-mail us at oligos@yale.edu for more information.

Pre-mixed 0.25 g "N" amidite (3.0ml)
or 3ml doped mixture

LV 40 nm cycle:

48 additions

LV 0.2 µm cycle:

45 additions

Normal 0.2 µm cycle:

17 additions

Normal 1.0 µm cycle:

17 additions

 

The Prices of Specialty Reagents:

In addition to the set-up and per-residue charges, the Glen Research or other company's list price +15% for the needed amount of specialty amidites and/or columns along with any ancillary reagents will be applied.

To eliminate issues of stability of the unincorporated monomers, we special-order the reagent for your oligos and discard any leftovers. We will work with you to group your orders so as to minimize your cost by maximizing the utilization of expensive monomers. If you prefer, we will work our way down a list of oligos until a specialty reagent is exhausted.

Generally, we will incorporate ANY commercially available modifier, not just those listed below, as long as it is particulate-free. To avoid issues of improper storage and handling, we recommend allowing us to order the modified phosphoramidite/column. However, if you would like to provide us with a phosphoramidite/column that you purchased or synthesized, a $250 surcharge for each different modification will apply. This surcharge covers the additional labor costs of modified phosphoramidite/column handling and storage, synthesizer programming, oligo processing and e-mail correspondence. Also, since we are not supplying the modified phosphoramidite/column, our usual quality guarantee does not apply and the oligos must be accepted "as is".

The following is a list of commonly ordered specialty reagents and columns. Remember, we will incorporate ANY commercially available modifier, not just those listed below, as long as it is particulate-free.
