Sample GSM3680734 Query DataSets for GSM3680734
Status Public on May 14, 2019
Title d9_1mM_Input
Sample type SRA
Source name d9 1mM_Glucose
Organism Mus musculus
Characteristics strain: C57BL/6
tissue: spleens and peripheral lymph nodes
cell type: CD8 T cells
days of glucose restriction: 5
genotype: OT-I
chip antibody: none (input)
Treatment protocol After 3 days, cells were switched to 1 mM glucose for 1 or 5 days (referred to as d5 and d9 respectively). 1 day before analysis, cells maintained in 1 mM glucose were treated with or without 5 mM sodium acetate (Sigma). Starting from day 2, and every day, cultured cells were harvested, washed, counted and plated at a concentration of 10^6 cells/ml in fresh medium with rhIL-2.
Growth protocol OVA peptide-specific T cells were isolated from spleens and peripheral lymph nodes of OT-I transgenic mice and activated with the ovalbumin peptide SIINFEKL (OVA257-264, 100 ng/ml, New England Peptide). T cells were cultured in RPMI 1640, added with 10% heat-inactivated fetal bovine serum (Gibco, lot n. 1640960), glutamine (4 mM), penicillin/streptomycin (1%), β-mercaptoethanol (55 μM) and glucose (concentrations indicated in the text). Cells were grown at 37° C, in 5% CO2, atmospheric O2, in a humidified incubator. Briefly, cells were activated on day 0 with OVA257-264, with rhIL-2 (100 U/ml, Peprotech) in medium containing 25 mM glucose.
Extracted molecule genomic DNA
Extraction protocol Fixed cell pellets (1% paraformaldehyde, 10 minutes, RT) were processed for multiplex RELACS (Arrigoni et al., 2018) and sequenced by the staff at the Deep-sequencing Facility at the Max-Planck-Institute for Immunobiology and Epigenetics.
