Quality

Your QC record

Your reference and the email you ordered with. The record is tied to the order, not to a link — so your sequences never sit on a page anyone can open.

What is on it, and what is deliberately not

Two of these come with any synthesis. The other two usually do not, and they are on the record because you need them before you can use the material.

Identity, on every oligo

Deconvoluted ESI-MS, free, on every item. We print the measured figure and the deviation, not just the word “pass”.

Delivered amount, in both units

The record carries the A260 yield as OD and as nmol, converted with the extinction coefficient of your own sequence rather than a flat 33 µg/OD rule. A 25-mer and a 60-mer do not hold the same nmol per OD — across real orders the spread runs to 24% — so the figure you resuspend against is the one for your sequence, not an average.

Purity, only if you ordered it

A UPLC or CE report is charged per oligo and has to be asked for — tick it in the order builder and the price is in your total before you commit. If you did not order it, the page says so rather than leaving a blank you might read as a pass.
