Hi -- I was wondering if anyone has had any luck with making 40kb jumping libraries using a Fosmid kit. I was looking at this NxSeq 40kb mate pair cloning kit . But really I have no idea what a good kit would be-- the whole process seems like there's a lot of room for mistakes. It will be for Illumina sequencing. Thanks!

What are you sequencing? You might be better off using long reads (PacBio or Moleculo), which won't be 40Kb but given the recent successes (such as assembling an entire Drosophila chromosome arm)
This is the only kit like it on the market, and it is indeed an involved protocol -- you are first making a cosmid library and then converting it to a sequencing library. -
I'm using Illumina technology for sequencing. I looked into PacBio, but the genome I'm trying to sequence is 1.6 GB, far too expensive for PacBio currently even only at 1X coverage. I might just try to find a company that does Fosmid libraries...Comment

Do you anticipate having difficulties (repeats, ploidy considerations etc)? Is there a related genome available?
Depending on how "finished" you want the genome to be, you may be able to get a lot done with normal libraries.Comment

The genome of interest is highly repetitive (estimated 21% tandem repeats, 42% repetitive). Unfortunately, there isn't a related genome available. I wanted to be able to do structural rearrangement analysis and comparative genomics between different species, which I would think requires a high degree of genome completion.Comment

Well .. in light of that your choice is going to be limited. Hopefully you can at least do a few SMRTcells on PacBio or other nanopore based technologies would become more generally available this year.
I know that oomycete genomes have been done (and they were certainly problematic back in the day).Comment

I might just wait until PacBio or SMRTcells become more affordable... as of right now it's about $6k to do 1X coverage of PacBio for a 1.6 GB genome.Comment

Hi jwag,
Doing a project search on Genohub for exactly 1x coverage on a 1.6 Gb genome yields the following PacBio service providers:
Genomax -- we're hoping too that nanopore tech comes online this year. By chance, are you one of the lucky few that has early access to the MinIon ?

I do not work in the lab but I know at least one person locally who was turned down. So not everyone who applied probably made it.Originally posted by Genohub View Post
Perhaps we should do an anonymous poll and see how many on SeqAnswers got selected?Comment

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...
