sequencing 1000 amplicons on miseq

Hi,

We are developing an amplicom sequencing project where the consensus primers for enrichment can be designed with amplicons between 800 to 1100 bp only. However, there is another catch, we do...

Nextera XT vs TruSeq PCR free

I have previously used the TruSeq DNA kit (only once) and now need to move on to use either Nextera XT or TruSeq PCR free kits and perform the whole library prep alone for the first time.
I would...

Barcode mismatch R1 and R2

Hi,

We are demultiplexing some in house barcodes, 5 nt in length as mentioned in a previous post for 2 x 150 Miseq runs
When this is done, there is a very high frequency of mismatch between R1...

Unhappy De-multiplexing, carryover from sample with highest reads?

Hello,
I use in house indexes (5nt) to tag my amplicons and pool 10 such samples and subject the pooled "sample" to library prep on TruSeq without fragmentation.

After demultiplexing for Illumina...
