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 (~400 bp fragments). 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?

Hi Hambone,
Internally, the development team has been using PCR products with ~100 to 500 ng of material. They are starting with the End Repair step of the 454 Rapid Library Preparation protocol and with good success.
I hope this helps,

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...05-06-2024, 07:48 AM -
The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...04-22-2024, 07:01 AM
