Starting Material
| Sample Type | Specificity | Comments |
|---|---|---|
| Genomic DNA (gDNA) | No specific treatment required | Standard material recommended |
| DNA extracted from FFPE tissue blocks | A restoration step will be performed in the laboratory prior to initiating the standard protocol (Illumina Infinium FFPE Sample Restore procedure). | |
| DNA extracted from Whole Genome Amplification (WGA) | Recommended Technologies : – REPLI-g (Qiagen) – OmniPLex (Rubicon Genomics) | Please contact the Client Management Office to validate project feasibility. |
Requirements – Quality and Quantity
Samples must be eluted in TE 1X buffer (10 mM Tris pH 8.0 / 1 mM EDTA) or in nuclease‑free ultrapure water.
Note that a fluorometric quantitative analysis is performed upon sample reception to validate DNA concentration.
| Minimum Volume | Minimum Concentration | Maximum Concentration |
|---|---|---|
| 20 uL | 30 ng/ µL | 200 ng/µL |
Concentration Verification
- Recommended method: Qubit or equivalent fluorometric method.
Note: Spectrophotometric methods such as Nanodrop are not recommended for measuring DNA concentration because they tend to overestimate the DNA concentration
Quality Verification
| Sample Type | Integrity | Recommended Method |
|---|---|---|
| Genomic DNA (gDNA) | Fragments >2 kb | Electrophoresis |
| DNA extracted from FFPE tissue blocks | N/A | N/A |
Purety Verification
- Recommended method: Nanodrop or equivalent spectrophotometric method.
- Target optical density ratios:
- 260/280 between 1,8 et 2,0
- 260/230 between 2,0 et 2,2.
Identification, Layout and Required Containers
Identification
The name written on the plate must be unique, legible, concise, and strictly identical to the name provided in the sample submission form.
Layout
Samples must be randomized by row prior to submission.
Samples from FFPE blocks must be processed independently: they should not be integrated into a standard genomic DNA plate and must be randomized separately.
For plates containing human samples, reserve one well for the addition of an internal positive control:
- Full plate: leave well H12 empty.
- Partially filled plate: leave the first well following the last sample empty, while respecting the required sample multiple for the array.
Required Containers
| Recommended 96‑well PCR Plates | Unaccepted 96‑well Plates |
|---|---|
| Full‑skirt PCR plates: – BioRad Hard-Shell 96-Well PCR Plates, skirted, Cat# HSP9601 – BioRad Microseal PCR plates 96-well clear, Cat# MSP9601 – Eppendorf twin.tec, Cat# 951020401 – Corning Thermowell GOLD, Cat# 3752 – Axygen 96-well PCR Microplate, Cat# PCR96FSC | – 96‑well cell culture plates – Opaque PCR plates – No‑skirt PCR plates |
| Recommended adhesive films: – Adhesive PCR Films; Thermo Fisher Scientific, Cat#AB-0558 – MicroSeal ’F’ Foil; Bio-Rad, Cat# MSF-1001 |

Transmission of Results
An automated message from Nanuq is sent to the project contacts upon completion of the project.
Analysis files are directly accessible through the Nanuq web application, under the Genotyping Reports section, as well as within the Documents, Analysis Reports, and Downloadable Data tabs.
All samples are retained for three (3) months following the project completion date.
