Which orientation should the index sequences have? (barcode sequences)

Demultiplexing service is included by default for all sequencing run types for standard barcodes. If you would like us to demultiplex, please provide barcodes in the libraries table in the COREOMICS submission system. Unfortunately, we cannot demultiplex inline barcodes. Required

When is a genome suitable for Bionano Optical Genome Mapping?

To check if the genome of your species of interest is suitable for Optical Genome Mapping on the Bioanao Saphyr, you should check the distribution of labeling sequence motifs. For this purpose, Bionano provides in silico digestion tools with the

Which DNA isolation protocols do you recommend for Illumina sequencing?

We recommend DNA isolations with spin-column kits/protocols that should include an RNase digestion step. Spin column kits have the advantage that they will reliably generate clean DNA samples that are fully dissolved and have fragment sizes longer than 10 kb

How should I QC my genomic DNA samples before sequencing?

DNA Sample Integrity: For Illumina short-read sequencing: DNA sample integrity should best be QC-ed by agarose gel-electrophoresis and ethidium bromide staining. “Safe” gel-stains such as Gel-Red work just as well. These stains will make both DNA and RNA visible. RNA

How to submit samples for Labchip GX RNA-QC and fragment analysis?

Assessing the integrity of RNA samples with the Bioanalyzer can be time-consuming and expensive since each run takes an hour and only 12 RNA can samples can be run. To make RNA QC more convenient and affordable we will be

Can I submit samples of lower integrity than recommended?

The sample integrity requirements are chosen to ensure the generation of high-quality data.  Please contact us before submitting such samples. It may be possible to use an alternative protocol that tolerates some sample degradation. When working with samples of lower integrity

Can you run samples with less than the recommended input material?

The sample amount requirements are chosen to ensure both, high-quality data and efficient processing. Most of the library prep protocols will generate sequenceable libraries with lower input amounts than request, often requiring additional PCR cycles. Processing often low-input samples often

How to purify DNA samples for long-read sequencing (PacBio, Nanopore)? How to remove polysaccharides?

DNA samples for long-read sequencing library preparations or also 10X genomics linked-reads have to be exceptionally pure. Please see the sample requirements.  For difficult DNA samples, especially all plant DNA samples with hard-to-remove contaminants (e.g. some polysaccharides), we recommend to carry out
