hi all,
Does anyone knows about illumina data downloadble from any published papers?
many thanks

I wanna do mRNA-seq on poplar, I review a bunch of literature without finding a single paper using pair-end sequencing, most of them use 454 sequencing. Does that mean pair-end sequencing does not work on poplar? Any suggestion?
What genome size? How many groups work on poplar sequencing?
Best results for de novo assembly from 454, of course. But for resequencing why not use pair-end read?

Nobody ever answered the original question, so here goes:
The fluorescent bases are 3'-O-azido dNTPs with fluorophores linked to the bases. The azide group on the 3' O blocks addition of another nucleotide, and you can use a phosphine (TCEP) to chemically cleave the azide from the 3' O and allow the next nucleotide to be added. I believe TCEP also cleaves the fluorophore from the base.
It's very clever, but unfortunately 3'-O-azido dNTPs are not available commercially. They would be fun to play with.

question... so paired end reads... are they from the same strand or the opposite??

Wrong thread. You'll get more eyes & brains on your question if you post in a more appropriate area (and say how many samples you are working with & what sort of species this is for)

Hello, I´m new in NGS. I want to sequence target regions using human genomic DNA. My purpose is to sequence de coding regions of 400 genes (around 1Mb). Which is the best approach?
In addition could you recommend me what software can be easily used to analyze data from exome assays.
Thank you.

I have a question about the software I can use to analyze the Illumina sequencing data. I'm doing targeted resequencing of long PCR fragments to find some EMS mutations. I'm waiting for my run to finish right now and meanwhile I'm looking for a suitable software. Any suggestion would be of great help to me. Thank you.

Is this material applicable to Illumina's systems today, or does it need updating?

Bridge Amplification
Hi All,
I'm new to this whole NGS business. I will be using an Illumina GAII. In a recent article from Bio Techniques, I read that longer (about 600bp) fragments can increase the uniformity of coverage across a targeted region. In the paper, amplicons were fragmented to 200bp prior to adaptor ligation and subsequence sequencing. Does anyone know why this would increase uniformity? Also, does anyone know if it is possible to successfully generate clusters during bridge amplification with fragments larger than 200-300 bp? And if so, how large?
THANKS!!

hello all I am very,very, very new to NGS. trying to learn as much as I can

There a small mistake on the picture. If we saw sequences of adaptors, primers and oligonucleotides
(Accurate whole human genome sequencing using reversible terminator chemistry.
David R. Bentley, Shankar Balasubramanian etc.
Nature, Vol 456 | 6 November 2008 | doi:10.1038/nature07517)
--- we can see that fragment links with oligonucleotide on the surface of flow cell not with adaptor but with additional sequences in primers, added by PCR.

Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...-

During the COVID-19 pandemic, scientists observed that while some individuals experienced severe illness when infected with SARS-CoV-2, others were barely affected. These disparities left researchers and clinicians wondering what causes the wide variations in response to viral infections and what role genetics plays.
Jean-Laurent Casanova, M.D., Ph.D., Professor at Rockefeller University, is a leading expert in this crossover between genetics and infectious...-
