150 of these are quoted rather than priced live. They are modifications our manufacturer can make but has not published a list price for. You can still put them in an order: the line goes into your basket marked Quoted, and the price comes back within one business day — you are not asked to start a separate enquiry.
Dye and quencher combinations are checked against published spectral ranges in the configurator, at the moment you pick them: you see the emission maximum, the quencher's absorbance range, and how much margin there is between them.
More than four modifications on one oligo, or something not in this table? That is a design-help case, not a dead end — send us the requirement and you get a design and a price within one business day.
