How to generate a Sample Sheet from sample/index data in BaseSpace

If you are using BaseSpace for sample entry but demultiplexing your data manually, you may have been frustrated that there is no facility to download your sample names and index tag data from BaseSpace as a sample sheet. This means you have to enter the same data twice – with the possibility of errors creeping […]

How to Import data for libraries with index tags into BaseSpace

In this blog we describe how to import lists of sample data with defined index tags into BaseSpace, and provide templates for TruSeqLT and TruSeqHT libraries. We have found this saves a lot of time and eliminates errors associated with manual entry. The Illumina NextSeq500 sequencer requires all users to complete sample data entry on […]

Illumina adapter and primer sequences

Illumina Adapter and Primer Sequences Illumina libraries are normally constructed by ligating adapters to short fragments (100 – 1000bp) of DNA. The exception to this is if Nextera is used (see end of this post) or where PCR amplicons have been constructed that already incorporate the P5/P7 ends that bind to the flowcell. Illumina Paired […]
