Design Notes

Users can change the 15 bases at the 5 'end according to their own needs, and replace them with the sequences that their machines want to recognize. The length of oligoT of DW_lineW can be appropriate, but it should not be too long or too short. The length of 5 'recognition sequence can also be designed according to the demand, but the data show that the total length of recognition sequence of lineL and lineW should not exceed 40 nt and should not be shorter than 20 nt. On average, the sequence of lineW recognition region should be 10 to 20 nt. Otherwise, the 19 bases at the 3' end are not recommended to change.


Source

The 5' end 15 nts sequence of DW_lineW is comes from a detection site of N gene of SARS-CoV-2.
