*Only customers with accounts in good standing are
eligible for this scale.
For this scale (25 nmol), we accept only VISA, Master Card,
or American Express credit/debit/gift cards. No other payment methods
are acceptable for this scale (however, other payment methods are
acceptable for all other synthesis scales). The card must be working at the time of shipping,
when it will be charged. All orders at the 25 nmol scale must be placed
by e-mail, using our special order form in Microsoft Excel format, please
e-mail us your request for the form
(the forms are not available for download from this site, because they
differ by country/province, language etc., and because not everyone is
eligible). The order form will automatically calculate the price of
each oligo, and the total for your order. 25 nmol (0.025 micromole) synthesis scale will yield
typically slightly more than 2 OD or 10 nmol final desalted product for a
20-mer oligo. Guaranteed minimum 2 OD260 (longer oligos) or 5 nmol (shorter oligos) for desalted non-modified oligos; modified
or additionally purified oligos
may yield less. Standard purity includes free desalting. All oligos are quantified
and three different units of measure are provided to the customer.
The relation between these three units is calculated by a computer, but
as an approximation for a 20 base long oligo, 10 nmole equals approx.
2 OD260 units or 60 microgram.
