Sample GSM7040844 Query DataSets for GSM7040844
Status Public on Sep 21, 2023
Title Patient_P1608_Pre_Treatment_scRNA-seq
Sample type SRA
Source name Primary CD138+ MM cells
Organism Homo sapiens
Characteristics patient number: P1608
time point: Pre
cell type: Primary CD138+ MM cells
library preparation: 10X Genomics Single Cell RNAseq v2 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 polyA RNA
Extraction protocol Single-cell library preparation for RNA-sequencing primary MM cells were processed according to 10X Genomics reagent Kits User Guide (CG00052 v2 Chemistry). Cells were partitioned into nanoliter-scale Gel Bead-In-Emulsions (GEMs) using 10X GemCode Technology. Primers containing (i) an Illumina R1 sequence, (ii) a 16 bp 10x barcode, (iii) a 10 bp Unique Molecular Identifier (UMI) and (iv) a poly-dT primer sequence were incubated with partitioned cells resulting in barcoded, full-length cDNA from poly-adenylated mRNA. Silane magnetic beads were used to remove leftover biochemical reagents/primers, then cDNA was amplified by PCR. Enzymatic Fragmentation and Size Selection was used to optimize cDNA amplicon size prior to library construction. R1 (read 1 primer sequence) were added during GEM incubation, whereas P5, P7, a sample index (i7), and R2 (read 2 primer sequence) were added during library construction via End Repair, A-tailing, Adaptor Ligation and PCR.
