Multiplex (12-plex) Illumina Adapter/Primer Sequences

Hi,

Has anyone got the multiplex oligo sequences that Illumina use in their Multiplex (12-plex) kits? (And their concentrations if they're known.)

Hi all,

Thanks for the technical details on this. Anyone got some information about bioinformatics on adapter contamination detection and removal. I tried using adapter sequences with eland to check for contamination, but less than 1% reads aligned. I expected more as less than 10% reads aligned to actual reference.

I know of a file one can specify in GA pipeline, to exclude sequences -- could someone point more details on the same? (i tried bioinformatics thread, but did not hear back )

thanks!

novoalign has 5' and 3' removal of adapter sequences prior to alignment. works well.

Hi,

I run the site you got the sequences from and am happy to see that you have posted the info here as well. I will attempt to keep the list up to date as new sequences are released. If there is any additional info you would like, let me know and I'll post it if possible.

Cheers,

Brent

Hey Brent,

Nice to have you, thanks for being willing to share with the community. I'm sure everyone would appreciate any info you have.

Adapter sequence

i know that the overhanging T is used to ligate with the added A from the DNA library, but thy is there a one base pair overhang on the other side? If you see how the sequence anneal there is an overhang on both ends. Both adapter sequences are 33 bases. If you only wanted the T overhang, why wouldn't you have 32 bases on one strand and 33 on the strand with the T overhang?

which adapters to use

Hi all,
I have a question:
I've prepared a cDNA library for solexa (double stranded) with 5' end after enzymatic cleavage by MMEI (see below). I would like to perform a single read from 5' (the left side with the MME sticky end). GEX2 adapter fits this site. My question is which adapter do I need for the 3' side to perform a single read of the 5' side (left side)?

5'_________? 3'
adapter Gex 2 3'___________
(MMEI side) which adapter on this side?

Can anyone answer this???

[hilahg]

the figure came out wrong... I hope you can still understand my question above....

Do pages 17 - 20 of this help?

[hilahg]

yes it helps, thank you

Perhaps the sequences are shown in Figure 2 and table S3 of this paper by Craig et al (http://www.nature.com/nmeth/journal/...th.1251.html)? I notice one of the authors has an Illumina affiliation and the paper describes 6 bp error corrected tags. Of course, they don't tell you outright which ones are the best but my guess is the 13 tags showing less than 2-fold difference in index frequencies between runs (Fig 2).

comparison of SE and PE sequences

Hi all
I put together a comparison of SR and PE sequences to get a quick look at regions of sequence similarity. Thought it might be useful for others (let me know if you spot errors). As far as I can tell, the SR and PE read 1 sequencing primers are identical, as are the SR and PE adapters with the T overhang. Seems to me that given this, it should be fine to run a PE library on an SR flowcell using SR reagents. Comments?
All the sequences are from the Bentley et al. nature paper supplementary info last year.

Hi!
I am trying to add adapters onto a cDNA pool by PCR. Has anyone done this before? I not sure how to design and orient my primers. I am currently looking to use the adapters for "Genomic DNA oligonucleotide sequences"
Thanks!

Does anyone happen to know the concentrations of the PR 5' adapter and the 10x v1.5 sRNA 3' adapter in the small RNA cloning kits?
