Sample submission guidelines

Get your samples ready for success.

Our portfolio covers genomics, transcriptomics, metagenomics, epigenomics, single-cell sequencing, genotyping and more. Quality nucleic acid input is what makes quality data output possible. These guidelines cover packaging, labeling, shipping and the minimum sample requirements for every service, so your project starts on the right foot.

Samples reach us pseudonymised: we receive a code, never a patient identity. Data is hosted in the European Economic Area, and GENXMAP holds a health data hosting addendum with its hosting provider, HDS-certified by BSI, for the projects that require it.

Sample requirements by type

Detailed requirements are set out on four dedicated pages, one per sample family. Quantitative PCR and proteomics are covered further down this page.

DNA sample requirements for sequencing

Minimum input, concentration, purity and integrity for whole-genome and exome sequencing, targeted panels, long-read platforms and epigenomics…

RNA sample requirements and RIN values

Minimum input, concentration, RIN and purity for bulk RNA-seq, small RNA, single-cell and spatial workflows. Including what we accept from…

Sample shipping and packaging

How to package, label and send your samples so they arrive in the condition they left in: dry ice and ambient shipments, tube and plate formats…

Sample collection protocols, by sample type

Blood, fresh and frozen tissue, FFPE blocks, saliva, swabs, stool, cell culture: how to collect, stabilise and store each one, and how much to…

Quantitative PCR & Genotyping platform

qPCR, digital PCR & genotyping samples

Covers the Quantitative PCR & Genotyping platform: qPCR, digital PCR (dPCR), SNP/CNV genotyping and pathogen-detection assays. Sample prep is lighter than full sequencing, and turnaround is fast.

Typical inputs. Genomic DNA or cDNA at 1–50 ng per reaction, depending on target abundance and assay design. Exact input is confirmed once your target and platform (qPCR vs. dPCR) are scoped. SNP genotyping and pathogen-detection assays generally follow the same DNA quality bar as our sequencing services (OD260/280 close to 1.8–2.0, no degradation). For RT-qPCR from RNA, use the same RNA quality thresholds as RNA sequencing (A260/280 ≥ 1.8, RIN ≥ 6 where applicable).

For SSR genotyping and HLA typing sample amounts, see the DNA sequencing table above: those assays share the same submission format.

Proteomics platform

Protein & proteomics samples

Our Proteomics platform covers in-house Western blot and biomarker panels, plus mass-spectrometry proteomics delivered through our specialized partner network.

Typical inputs. Western blot / biomarker panels: 10–30 µg of total protein lysate per lane is a common starting point, though this varies by target abundance and antibody sensitivity. Mass-spectrometry proteomics input (depth-dependent, from targeted panels to deep shotgun profiling) is confirmed directly with our partner lab once your project is scoped. For any protein workflow, keep samples cold (4 °C short-term) or snap-frozen at −80 °C, and avoid repeated freeze/thaw of lysates.
