Hello, my ddRAD libraries (mean 550 pb) contain the first 5 identical bases at their ends, belonging to the partial restriction site. They will be paired-end sequenced in a MiSeq. I would like to modify the Illumina sequencing primers by adding those 5 bases at the 3 prime end of each primer. Thus, a higher diversity is expected in the first sequenced bases and also an adequate cluster generation. Does anyone have experience with this approach? and the use or not, and its PhiX concentration. Thank you. Best regards.

It could work - however you will not be able to sue the PhiX libraries as spike in since you will can't use the Illumina sequencing primers together with your extended versions. -
Thank you. It is right. So the question is what can work best. 1) Use modified primers to bypass the restriction site or 2) use a high concentration of PhiX (how much?).Comment

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...Today, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
