Sample GSM7111770 Query DataSets for GSM7111770
Status Public on Feb 17, 2025
Title H3WT_hemi__P3
Sample type SRA
 
Source name Human tissue GBM
Organism Homo sapiens
Characteristics age: 8 days old
tissue: pediatric high grade glioma
Extracted molecule polyA RNA
Extraction protocol Smart-seq2 protocol, 10X Genomics protocol
Smart-seq2: Library was performed according to the manufacter’s instructions (single cell 3’ v2 protocol). Briefly: RNA was purified with Agencourt RNAClean. Oligo-dT primed reverse transcription (RT) was performed using Maxima H Minus reverse transcriptase (Life Technologies) and a template-switching oligonucleotide (TSO; Qiagen). For the reverse transcription step, Maxima RNaseH-minus RT (200 U/ml) was used as the RT enzyme at 2U/ml. The RT step was performed at 50 Celsius degree for 90 minutes followed by 85 Celsius degree for 5 minutes. In the PCR pre-amplification step, an ISPCR primer was used at 0.2 mM and PCR was performed for 21 cycles. ). PCR purification was performed using AMpure XP beads at 0.8X. Libraries were enriched with dual indexes using Illumina Nextera XT Library Prep kits
10X Genomics: The isolated single cells (T cells, Myeloid cells, or tumor cells) were loaded into separate channels of a Single Cell Chip A with reverse transcriptase reagent mixture and 50ul gel beads according to the manufacturer’s protocol.Chips were next loaded into the 10X Genomics Chromium Controller for single-cell partitioning, immediately followed by emulsion recovery from the chip and incubated in a Thermocycler for the RT reaction. cDNA isolation and library preparation were completed as per the manufacturer’s protocol. Isolated cDNA was amplified (13 cycles). cDNA was allocated for preparation of a gene expression library or TCR enrichment/library preparation with the Chromium Single Cell V(D)J TCR kit (10X Genomics)
