Hi,
I wanted to ask how to calculate the expected depth coverage in 454 if I know the size of the sequenced genome?

Your local sequencing center should be able to tell you how much raw sequence data a plate (or half a plate, 1/4, 1/8 or even 1/16 of a plate) would give you (in base pairs), so divide this by the estimated genome size. That will will give you an upper bound on the coverage assuming uniformity of coverage, linear amplification, no contamination, etc.
If you want more practical comments, I suggest you tell the forum what kind of organism it is and the estimated genome size. The GC% might also be important... -
GC content
Why is GC content important? how to consider it?Last edited by dina; 10-03-2009, 06:27 AM.Comment

Well, not directly, but extreme GC values could cause trouble at several steps.Comment

GC
So, what would you sugggest? I have to check the GC content of the whole genome before the sequencing? and if it is high , what can I so?Comment

If you have any genes or ESTs already sequenced you should be able to guess the GC%, or even look at related organisms. If it is extreme then some background reading of the literature might be in order - but you'll probably be fine.Comment

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 -
Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.
We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing...
