Sample GSM7040830 Query DataSets for GSM7040830
Status Public on Sep 21, 2023
Title Patient_P1299_Pre_Treatment_ATAC-seq
Sample type SRA
Source name Primary CD138+ MM cells
Organism Homo sapiens
Characteristics patient number: P1299
time point: Pre
cell type: Primary CD138+ MM cells
library preparation: 10X Genomics Single Cell ATACseq v1 Chemistry
Growth protocol Primary CD138+ MM cells were obtained from the BM aspirates of MM patients at the time of diagnostic procedure, using positive selection with CD138 microbeads (Miltenyi Biotech, Auburn, CA) and accordingly to manufacturer’s instructions. CD138+ fractions were subsequently analyzed by flow cytometry in order to confirm the sample’s purity. HEK293T cells were cultured in Dulbecco’s Modified Eagle’s Medium (DMEM) supplemented with 10% FBS, 100 U/mL penicillin and 100 g/mL streptomycin. All of the listed cells above were cultured at 37°C and 5% CO2.
Extracted molecule genomic DNA
Extraction protocol For single-cell library preparation for ATAC-seq the desired number of nuclei were targeted and processed according to 10X Genomics Reagent Kits User Guide (CG000168). The Nuclei Isolation was performed ad indicated in the nuclei Isolation protocol for Single Cell ATAC Sequencing (10x Genomics). Based on the starting number of cells and desired final nuclei concentration primary MM cells were washed, lysed and re-suspended in appropriate volume of chilled Diluted Nuclei Buffer. The resulting nuclei were then immediately used to generate scATAC-seq libraries. ScATAC-seq libraries were prepared according to 10X Genomics Reagent Kits User Guide. Briefly, the desired number of nuclei were combined with ATAC Buffer and master mix to form transposed Nuclei. Single-cell GEMs were then generated, amplified and subjected to bead clean-ups. Indexed sequencing libraries were constructed using Chromium i7 Sample Index and the barcode sequencing libraries subjected to a final bead clean-up prior to quantification.
