*Only customers with accounts in good standing are
eligible for this scale. Generally speaking, the best way to ensure that
the account is in good standing (especially for customers that are not from
North American educational institutions) is to use credit or debit card for payment.
We accept VISA, Master Card, and American Express credit cards, as well as
VISA and Master Card debit cards. All orders at the 100 nmole 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). 100 nmole (0.1 micromole) synthesis scale will yield
typically 0.040-0.150 micromole (40-150 nmole) final product for a regular
size, standard purity oligo. Guaranteed minimum 5 OD260. 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, 50 nmole equals approx.
10 OD260 units or 300 microgram.
