ALPHA ADN

*The relations between different units for oligo quantification are calculated by a computer, but as an approximation for a 20-base long oligo, 50 nmole equals approx. 10 OD units (at 260 nm wavelength) or 300 micrograms. Example: An 8-mer oligo CTACTAGC is ordered at the 100 nmole scale; the final DNA quantity delivered to the customer is 71 nmole (71000 pmole), which for this particular oligo equals 168 micrograms and 5.3 OD units. Our guaranteed minimum is either 6 OD or 25 nmole. The delivered product does not have 6 OD (it is only 5.3 OD units), but at 71 nmole, it is almost three times more than the guaranteed 25 nmole; therefore, the actual yield is considered sufficient (higher than the guaranteed minimum). The above table is for desalted oligos without additional purifications or modifications. The guaranteed minimum for oligos with additional purification is usually 40% of the guaranteed minimum for desalted oligos. Oligos with additional modifications may yield less than the..
