I am planning to deep sequence material from 13 samples. For this, I am isolating RNA from various organs, reverse transcribing with a gene specific primer and performing a multiplex PCR (all products are ~400 bp). Then, I will ligate a barcode to the PCR product from each sample and sequence. Since I am jumping into the middle of the standard 454 prep, can someone please tell me how much starting material I need for each sample for a full 454 plate?

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...Yesterday, 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
