| Title |
primary melanocyte C18_1 |
| Sample type |
genomic |
| |
|
| Source name |
primary melanocyte
|
| Organism |
Homo sapiens |
| Characteristics |
disease: Melanocyte
tissue: SKin
|
| Growth protocol |
Primary melanocyte cultures were grown in Dermal Cell Basal Medium (ATCC® PCS-200-030™) supplemented with Melanocyte Growth Kit (ATCC® PCS-200-041™) and 1% Amphotericin B/Penicillin/Streptomycin (120-096-711, Quality Biological) at 37°C with 5% CO2, and trypsinized with Trypsin/EDTA Solution (R-001-100, Cascade Biologics) as well as Trypsin Neutralizer Solution (R-002-100, Cascade Biologics). Media was changed every 2-3 days when necessary.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was isolated from primary melanocyte cultrue using Gentra Puregene Cell Kit (158745, Qiagen)
|
| Label |
C-Bio and A-DNP
|
| Label protocol |
200ng of genomic DNA, quantitated using Quant-iT™ PicoGreen dsDNA Reagent (ThermoFisher Scientific, Waltham, MA, USA) is denatured and neutralized, then isothermally amplified by whole-genome amplification. The amplified product is enzymatically fragmented, then precipitated and re-suspended.
|
| |
|
| Hybridization protocol |
Resuspended samples are denatured, then hybridized to locus-specific 50-mer oligonucleotides which are attached to 1-micron beads on the BeadChip. These 50-mer probes stop one base before the location of interest. Enzymatic single-base extension of the oligos on the BeadChip, using the captured DNA as a template, incorporates tagged nucleotides on the BeadChip, which are subsequently fluorophore-labeled during staining. The fluorescent label determines the genotype call for the sample.
|
| Scan protocol |
The Illumina iScan scans the BeadChips at two wavelengths to detect the fluorescent label, creating image files that are converted into genotype calls based on the detected fluorescence.
