I know a few people other than myself were looking for the concentrations of the Solexa v1.5 kit (and well all of them in my case) adapters. I spoke with a tech support person from Illumina and they told me the concentrations of the stock solutions before any of the dilutions were as such:

3' sRNA Adapter v1.5 = 5µM
SRA 5' Adapter = 5µM

Other oligos:

SRA RT primer = 100µM
Primer GX1/2 = 25µM

Hope that helps!

Hi - I am a bit confused about the Illumina Paired end adaptors..

Are they a Y adaptor (illustrated below) where you have 2 primers which are complementary at the end you ligate to your library (ie i should only synthesise 2 oligos)

5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCT-3'
                      |||||||||||||
3'-GAGCCGTAAGGACGACTTGGCGAGAAGGCTAG-PO4-3'

or are they two sets of fully complementary primers, so i should order 4 oligos? this is what it seems to illustrate in post #7

5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCT-3'
   ||||||||||||||||||||||||||||||||
3'-TGTGAGAAAGGGATGTGCTGCGAGAAGGCTAG-PO4-5'
and
5'-PO4-GATCGGAAGAGCGGTTCAGCAGGAATGCCGAG-3'
       ||||||||||||||||||||||||||||||||
   3'-TCTAGCCTTCTCGCCAAGTCGTCCTTACGGCTC-5'

Cheers!

Hi all,
thank you for all the replies. It was very helpful.
I have another question regarding MME cleavage. I use this protocol for library preparation(with MMEI cleavage): http://keck.med.yale.edu/microarrays...04241_RevA.pdf

I'm experiencing trouble with the MME cutting procedure as it doesnt! cleave. Has anyone experienced this problem in the library preparation process. I use MME from NEB
and tried various concentrations but without improvement...

Thanks,

Hilah

[kmcarr]

frozenlyse,

You would only synthesize the two oligos as in your first figure. Look at this thread http://seqanswers.com/forums/showthread.php?t=1169 (in particular the PDF attachment)

Genomic PCR Oligo Mix

so it's friday evening, and i was supposed to be amplifying my library before going home tonight however my coworker used all of our amplifying PCR Primers 2.1 and 1.1 for SE sequencing and I can't find an accurately labeled figure of the sequences for these SE PCR primers that Illumina sends out. I'm finding PE sequences everywhere though.

clarification?

Thanks.

You can get the SE and PE PCR primer sequences from the supplementary info of Bentley et al 2009 (http://www.ncbi.nlm.nih.gov/pubmed/18987734). I pulled these and did a comparison of PE and SE primers/adapters (p 9 of attached pdf).

[der_eiskern]

thanks greigite!

[tgdeering]

I am looking into making my own SE primers and noticed in the Bentley et al 2009 paper that they used phosphorothioate modified primers. Does anyone else who uses their own primers do this? Also, what purification for the oligos is needed? Standard desalting, PAGE, etc?

[der_eiskern]

i just got HPLC purified phosphorothioate primers today in the post. I'll try to post how happy i am with them.

i've run into problems after gel purifying the ligated adaptors with inefficient amplification, hopefully this helps...

we'll see.

[der_eiskern]

tgdeering, phosphorothioate fixed my problems. before i could barely see a band after amplification but with phosphorothioate primers i got maximal amplification with iProof.

New to this so my knowledge-base is still quite limited so be gentle in reply, please
We will prepare miRNA-Seq library and send it out for sequencing on a GAII. Can anyone confirm that these adapter/Primer sequences first reported by ECO have (can) been used successfully on the GAII (and presumably GAIIx)?

Was (is) there a GAI instrument? Does it require different Adapter/Primer sequences? Can't find any evidence of a GAI version on Illumina website.
Thanks in advance

[Samodha]

Hi,
I am New to Illumina sequencing. This is a great resource!!! I was wondering if anyone has figured out the sequences of the multiplexing adaptors.

Thanks

[bp79]

Thanks for all the helpful stuff on here. A quick newbie question: are all these adapter sequences etc definitely unchanged across the various incarnations of Illumina (GAI, IIe, IIx) - I think so but not certain?
Thanks
bp

[der_eiskern]

i can say the SE adaptors worked on my GAIIx SE sequencing runs last August with the latest kits at the time.

merging MAQ map files exceed limits

Dear all,

I have 45M (25M in pairs) aligned Solexa reads of 62 bp length in several map files after running Maq map. I have removed the duplicates and now I want to merge them, but get an error message that says that the size of the merged file becomes to big (> 2.1G). How I can get around this?

Are there scripts available that allow me to split the mapfiles according to chromosome number?


Kind regards
