STR mode

What’s the “STR” mode? #

Short Tandem Repeats (STRs) are regions within the genome consisting of multiple repeating DNA sequences. The STR mode is specifically tailored for designing primers to amplify regions flanking STRs or any target regions intended to be amplified in their entirety.

In scenarios where the target region’s size exceeds the maximum allowed product size, a tiling design strategy is employed with a default setting of two tubes to ensure 100% coverage of the target.

The STR mode is designed to avoid placing primers directly on the target regions, instead selecting them from the surrounding flank areas for optimal amplification.
